Building Your Geoprofessional Network: From Conference Small Talk to Lasting Business Relationships

/in /by

For many geoprofessionals, networking events can feel like the furthest thing from anything we have been educated or trained for.  Instead of focusing on technical concepts within our disciplines, we need to socialize, engage in some level of small talk, and work to establish valuable professional connections. And just like our technical work, sometimes you find success immediately, and sometimes the task is harder than we would like.

However, the key to networking in the geoprofessional world is that it’s not about collecting business cards like soil samples (though some people seem to think it is). It’s about building genuine relationships with people who understand why you get excited about what you do and why doing it well brings you joy.

The Conference Conundrum

If you haven’t been there yet, you will be or should plan to be.  Standing there in a hotel ballroom with a lukewarm coffee, surrounded by people wearing name tags and that slightly desperate look of someone trying to figure out how to start a conversation with a stranger. The key is remembering that everyone else is in the exact same situation; they just may be better at hiding their networking dread.

The secret weapon? Ask about their work, not their business. “What’s the most interesting project you’ve worked on lately?” beats “What does your company do?” every single time. People love talking about cool projects, unusual site conditions, or (just like you) whatever gets their blood pumping while they’re working. These stories are what make our industry fascinating, and they’re infinitely more memorable than another elevator pitch about the comprehensive services your firm can provide.

The Art of the Follow-Up That Doesn’t Feel Stalky

So, you’ve had a great conversation about contaminated groundwater plumes or the challenges of drilling a tough site. You’ve exchanged business cards. Now what? This is where most networking attempts often fail, despite good intentions and business cards left forgotten in laptop bags.

The best window for follow-up is 48-72 hours after the event, while the conversation is still fresh in both your minds. Send a brief LinkedIn connection request or email that references something specific from your conversation. “Great meeting you at the conference, I’d love to hear how that remediation project turns out” is a personal and memorable way to follow up. “Nice meeting you, let’s stay in touch” is what everyone sends and gets immediately forgotten.

Beyond the Business Card Shuffle

Real networking happens in the time between formal presentations. The best conversations often occur in the hallway between sessions, during the coffee break, or at the hotel bar after the reception winds down (my favorite). These informal moments are where people let their guard down and share their real stories.  Stories about the projects that went sideways, the regulatory challenges that were skipped during the presentations, and the lessons they’ve learned the hard way.

Don’t just attend the main sessions and disappear. Stick around for the round table discussions, join the dinner groups, and participate in the field trips if they’re offered. Some of the most valuable connections happen when you’re able to connect with a peer or prospective client outside of the normal conference agenda.

The LinkedIn Strategy That Actually Works

LinkedIn is like the digital equivalent of a professional conference that never ends. It can be incredibly valuable or completely overwhelming, depending on how you approach it. The key is being genuinely helpful rather than constantly promotional.

Share interesting articles about industry trends, repost an interesting post from someone else, and comment thoughtfully on it if you choose to.  You can share your own project experiences (within confidentiality limits) and step outside our typical geoprofessional comfort zone to celebrate some of the great things we do from time to time. When someone in your network posts about a challenge they’re facing, you might offer helpful insights if you have them, maybe through a direct message. This positions you as a knowledgeable resource rather than just another person trying to sell something.

And please, for the love of all that’s geoprofessional, personalize your connection requests. “I’d like to add you to my professional network” tells me nothing about why you want to connect or how we might help each other. You can be much more personal than that.

The Long Game of Professional Relationships

The best business relationships develop slowly, like groundwater contamination, but in a good way. That geologist you met at last year’s conference might not have any immediate project opportunities, but they could be the perfect collaborator for a proposal six months from now, or they might refer a client to you next year when they’re too busy to take on new work.

Keep track of your connections beyond just adding them on LinkedIn. Make notes about their specialties, their company’s focus areas, interesting projects they mentioned, or personal details they shared (kids, hobbies, professional goals). This information becomes invaluable when you’re looking for the right person for a specific project or when you want to make a meaningful referral.

The Referral Economy

As most of us realize, there’s a big part of geoprofessional consulting that isn’t taught in schools. The missing class we should have taken would have taught everyone that a significant portion of consulting work comes through referrals and professional relationships. That geotechnical consultant who specializes in the education market might need a geologist for geologic hazard report. The environmental firm that’s too busy to take on a new project might refer it to someone they trust.

The key to becoming someone who receives referrals is becoming someone who makes them. When you hear about opportunities that aren’t a good fit for your firm, refer them to appropriate colleagues. When clients ask for recommendations for services you don’t provide, have a list of trusted professionals to refer them to. This kind of helpfulness gets remembered and reciprocated.

Conference Survival Guide for Introverts

Not everyone is naturally comfortable working a room full of strangers (shocking, right?). If the thought of networking events makes you want to hide at the back of the room, you’re not alone.

Start small. Set a goal of having one meaningful conversation per event rather than trying to meet everyone in the room. Attend smaller, more focused events where you’re more likely to meet people with a similar focus or interests. Volunteering for conference committees or helping with registration gives you an easy conversation starter and a reason to interact with attendees.

Remember that quality always beats quantity. One genuine connection is worth more than a stack of business cards from people you’ll never remember, or that won’t remember you!

The Digital Age Networking Balance

Professional organizations have increasingly transitioned their networking online, especially since the pandemic. Virtual events, online forums, and social media groups provide new opportunities to connect with professionals worldwide. But digital networking requires a slightly different approach than in-person events.

Digital networking requires you to be more intentional about your participation in online discussions. Most of the time, you need to unmute yourself and be ready to speak at the appropriate moment. Ask thoughtful questions, share relevant experiences, help others, or provide feedback when you can. Online networking makes participation in a wide range of meetings or events a more achievable reality than it might be if they were held exclusively in person. They also actually work well for many professionals, as you are often offered the opportunity to think about your responses and participate when it fits your schedule.

Building Your Personal Board of Directors

Think of networking not just as finding clients or job opportunities, but as building what business experts call a “personal board of directors.” This is really a group of trusted peers or colleagues who can provide advice, different perspectives, and career guidance. This could include:

  • Senior professionals who can offer insight and mentorship
  • Peers who are facing similar challenges and can share strategies
  • Junior professionals who bring fresh perspectives and energy
  • Professionals in adjacent fields who can offer different viewpoints

These relationships are often the most valuable for long-term career development, even if they don’t directly lead to immediate business opportunities. Sometimes you can even find all of them in one networking organization!

The Authenticity Factor

The most important networking advice is also the simplest: always be genuine. People can sense when you’re only talking to them because you want something from them. Instead, approach networking with curiosity about other people’s work and a genuine desire to learn about them, as well as a willingness to be helpful when possible.

Share your own challenges and successes honestly. Ask for advice when you need it and offer help or feedback when you can provide it. The goal isn’t to present yourself as the perfect professional who has everything figured out!  This is a big mistake many people make, or think they need to live up to early in their careers.  Your goal should be to develop authentic relationships with people who understand your value if they are a client, and the unique challenges and rewards of geoprofessional work if they are a peer.

Making It Sustainable

Networking isn’t a race to a finish; it’s a long game that requires consistency. A steady, modest effort over time will produce better results than intense bursts followed by months of neglect. Set aside a little time each week to maintain your professional relationships. It could be as simple as congratulating someone on a new job, sharing an interesting article, or just checking in to see how things are going.

The most successful professionals in our industry aren’t necessarily the most technically brilliant (though technical competence is always important). They’re often the ones who have built strong networks of colleagues who trust them, refer work to them, and want to collaborate with them on projects.

Remember, every expert was once a beginner, every successful firm started with zero clients, and every industry leader had to introduce themselves to strangers at their first conference. The geoprofessional community is generally welcoming and supportive.  You just have to be willing to engage with it.

Now get out there and start building those relationships. Your future self (and your business development goals) will thank you.

Wastewater Discharge Testing in Food Manufacturing: Why Choosing the Right Lab Is Essential

/in /by

In the food manufacturing industry, wastewater discharge is a critical compliance issue. Whether your facility processes dairy, meat, beverages, or packaged foods, your wastewater must meet specific discharge limits before it enters municipal systems or the environment.

Accurate sampling and testing are not just best practices—they are regulatory requirements. And the quality of your compliance program depends heavily on the expertise of the environmental testing laboratory you choose.

Regulatory Compliance Is a Business Imperative

Food manufacturers are subject to a complex framework of environmental regulations, including:
– EPA’s National Pretreatment Program
– NPDES (National Pollutant Discharge Elimination System) permits
– Local POTW (Publicly Owned Treatment Works) discharge limits
– State-specific environmental compliance programs

Non-compliance can result in:
– Fines and penalties
– Permit violations and enforcement actions
– Operational disruptions
– Reputational damage

Why Lab Expertise Makes a Difference

1. Accurate, Defensible Data

A qualified lab uses EPA-approved methods and maintains rigorous QA/QC protocols to ensure your results are accurate, traceable, and defensible during audits or inspections.

2. Industry-Specific Understanding

Food manufacturing wastewater often contains:
– High BOD/COD from organic residues
– Elevated FOG from oils and greases
– Variable pH and nutrient levels
– Cleaning agents and sanitizers

An experienced lab understands these profiles and can tailor your testing plan to meet permit requirements and operational realities.

3. Expertise in Sampling Techniques

Proper sampling is just as important as accurate testing. A lab experienced in both grab and composite sampling techniques ensures:
– The correct method is used based on your permit and discharge characteristics
– Samples are collected at the right time, location, and frequency
– Chain-of-custody and holding time requirements are strictly followed

Improper sampling is one of the most common causes of non-compliance. A lab that understands the nuances of sampling in food manufacturing environments can help you avoid costly mistakes.

4. Regulatory Reporting and Support

A strong lab partner doesn’t just deliver results—they help you interpret them so you can adequately prepare your discharge monitoring reports (DMRs) and effectively respond to regulatory inquiries. This support is invaluable during inspections, audits, or permit renewals.

What to Look for in a Lab Partner

When evaluating environmental testing labs, ask:
– Are they NELAC or state-certified for the parameters you need?
– Do they have experience with testing food manufacturing wastewater?
– Can they provide sampling services and ensure compliance with your permit?
– Are they reliable and responsive?

– Do they track and measure turnaround time success and offer digital reporting tools?
– Do they maintain a robust QA/QC program and achieve high percent success on performance testing samples?

Final Thoughts

Wastewater discharge compliance is a technical and regulatory challenge that requires precision, documentation, and expertise. Choosing a laboratory that understands your industry, your permit requirements, and the importance of proper sampling techniques is essential to staying compliant and avoiding costly disruptions.

If your facility is looking for a lab partner that delivers more than just test results—one that brings regulatory insight, sampling expertise, and industry-specific knowledge—make sure you’re working with a team that’s as committed to compliance as you are.

The Reality Check of a Project Timeline: Why Does Everything Take Longer Than You Think?

/in , /by

The Reality Check of a Project Timeline: Why Does Everything Take Longer Than You Think?

If you’re beyond “rookie” status in the geoprofessions, you’ve probably experienced that unsettling feeling when a simple two-week project stretches into its second month. Sound familiar?  Well, welcome to the club.  We meet for coffee every morning at 6:00 AM and for drinks at 6:00 PM, as those are the only times we’re not fielding calls about delayed deliverables.

There’s a sad reality in our disciplines: everything takes longer than expected. Always. In baseball, it would be like trying to deliver a perfect strike while the pitch clock is ticking down, but the mound keeps shifting under your feet and the umpire keeps changing the strike zone throughout your delivery. But here’s the thing: once you accept this universal truth, you can plan for it and look like a seasoned professional instead of recurrently apologizing for flying past your promised due date or blowing your budget.

The Basis of Geoprofessional Optimism

Let’s start with a moment of brutal honesty: we all could be better at estimating timelines. I even know of one coworker who calls estimating a W.A.G., which is a reference to a wild guess, with a special middle word that you can determine on your own. That might be a bit extreme, but the point emphasizes the uncertainty we all face with estimates. This isn’t because we’re bad at our jobs, but because we’re human beings dealing with the realities of a world that specializes in surprises and doesn’t really care about our project schedules.

When we say, “this should take about two weeks,” what we really mean is “if everything goes perfectly, we encounter zero surprises, all of our equipment works flawlessly, the weather cooperates, the lab doesn’t have a backlog, any regulatory gods involved smile upon us, or the contractor we’re inspecting keeps a schedule we anticipated, we might finish in two weeks.” But we don’t say all that because clients tend to get nervous when you mention geoprofessional gods.

The Underground Conspiracy Theory

Subsurface explorations seem to have a sense of humor, and unfortunately, it’s not the same as ours. That routine geotechnical exploration that you notified underground service alert about? Surprise! There’s a pressurized sewage line buried exactly where you planned to drill. That straightforward Phase II ESA? Nope! The contamination plume decided to take a scenic route that defies all hydrogeological logic. The bedrock that should be at 10 feet suddenly appears at 3 feet, or you suddenly have five feet of undocumented fill. It’s almost as if the earth knows when you’ve promised a client a quick turnaround and responds by throwing every possible curveball your way.

The Construction Site Slot Machine

Does anyone have the secret to predicting the timeline of the actual construction process? Contractors are building amazing things, but their schedules exist in a dimension where “we’ll be ready for testing tomorrow” can mean anything from 6 AM sharp to sometime next Thursday when the planets align.

Many of you CoMET personnel have likely experienced your staff arriving at the crack of dawn with your testing equipment, ready to sample concrete or conduct a soil compaction test, only to find that the crew is still waiting for materials that won’t arrive for a few hours, or perhaps even tomorrow. Meanwhile, you’ve faced challenges with your client in obtaining a change order for a job that was filled with delays beyond your control, despite the expectation that the budget was “not to exceed”.

The real kicker? Just when you reschedule and mobilize your team for the new “confirmed” time of 10:00 AM tomorrow, you get the call that they’ve moved up the schedule and need you there in two hours because the concrete crew can only make it today. It’s like playing a slot machine where the symbols are schedule changes and delays, contractor means and methods, and surprise change orders, and the jackpot would be completing your testing scope on the originally planned day.

The Regulatory Roulette Wheel

Then there’s our favorite wild card: regulatory agencies. We know they are doing important work, but their review timelines can sometimes exist in a parallel universe where two weeks can easily turn into two months.

You submit a perfectly prepared report one day, expecting feedback in a standard timeframe, and suddenly it’s three weeks later and you’re still waiting. Meanwhile, you have to be accountable to a client that is asking for daily updates as if you have a direct line to the regulator’s desk (spoiler alert: you don’t, and even if you did, they’re probably reviewing someone else’s report from a month before you submitted yours).

The Art of Strategic Padding

Here’s where we get into the real strategy, which is building some realistic buffers into your timelines without looking like you are just making numbers up. Remember, this isn’t about being pessimistic about the project. It’s about being professionally prepared for reality.

There are several approaches, and they might differ depending on your specific discipline or even type of project.  But you need to think about what might need to be considered for the project.  One approach is to start with your best-case scenario estimate, then add a small buffer (maybe 10% to 20% additional time, depending on project variables). For drilling projects or projects that you don’t have direct control over, you might factor in some contingency for equipment delays, unexpected weather considerations, and the inevitable “we need to go deeper” or “we didn’t expect this” moments. For laboratory work, remember that your samples aren’t the only ones they are working on, and holidays or vacations are considerations for labs as much as they are for your field or project team.

Don’t present this as pessimism to clients, or that you are expecting the worst. You can frame it as proactive professional behavior based on your experience and your best effort to account for industry-standard variables, which will help avoid potential cost overruns for you and minimize the need for a budget amendment for them. It’s simply good business! This not only sounds much more professional than “everything always goes wrong,” but is truly a more responsible approach towards accountability to your firm, and as a business partner for your client.

The Case for Proactive Communication

The secret to good project timeline management isn’t perfect scheduling, but rather proactive communication. When you sense a delay coming (and if you haven’t experienced it already, you will learn this sixth sense), get ahead of it. Don’t wait until the day of the deadline to announce that you need another week.

A call that starts with “I wanted to give you a heads up that we’ve encountered an unexpected condition that might affect our timeline”  is infinitely better than one that starts with “So, about that report you’re expecting this afternoon…” The first makes you look professional and proactive. The second makes you look like you’ve been hiding behind your desk, hoping the problem will somehow solve itself. Which approach do you think your client is more likely to understand and appreciate?

The Long-Term Reputation Play

Here’s the counterintuitive truth that sometimes takes years to realize: clients remember professionals and firms that deliver consistently more than those that promise aggressively. It is ALWAYS better to underpromise and overdeliver than to constantly have to explain why you’re running behind. A geoprofessional should work to build a reputation of reliability and consistency, even if it means slightly longer initial timelines. The result of this approach will be a reduction in marketing effort through repeat business and referrals.

When you do finish ahead of schedule or under budget (and yes, it does happen occasionally, often when you’ve planned for everything to go wrong and nothing does), your client will see it as a welcome bonus rather than the bare minimum expectation.

Embracing the Unpredictable

The geoprofessional discipline includes project scopes that vary widely and are inherently unpredictable, and that’s actually part of what makes our work interesting. The key is to build processes and establish expectations that work with this reality, rather than against it (or you). Accept that surprises are normal, plan for variability, communicate proactively, and be as prepared as you can to take the changes in stride. After all, if geoprofessional consulting were predictable, it would probably be a lot more boring.

The Science of Testing For Mercury in Wildfire Impacted Soil and Groundwater

/in /by

THE SCIENCE OF TESTING FOR MERCURY IN WILDFIRE IMPACTED SOIL AND GROUNDWATER

California’s increasing wildfire frequency and intensity have raised significant environmental concerns, including the mobilization of toxic substances like mercury (Hg). Mercury, a persistent and bioaccumulative heavy metal, can be released from both natural and anthropogenic sources during wildfires, posing risks to ecosystems and human health.

Wildfires can significantly alter the chemical and physical properties of soil, leading to:

  • Thermal release of mercury from soil and vegetation.
  • Increased erosion of contaminated soils into waterways.
  • Enhanced methylation of mercury due to post-fire changes in organic matter and microbial activity.

Post-wildfire conditions facilitate mercury transport through:

  • Surface runoff during rain events, carrying ash and soil into streams and lakes.
  • Leaching into groundwater, especially in areas with permeable soils and shallow aquifers.
  • Bioaccumulation in aquatic food webs, affecting fish and wildlife.

The California Water Science Center has been modeling these processes to understand how mercury moves through watersheds post-fire

According to the State Water Resources Control Board, mercury has been detected in public water wells across California. Sixteen (16) out of 9,201 wells tested between 2007–2017 had mercury levels above the federal Maximum Contaminant Level (MCL) of 2 µg/L. The highest concentrations were found in Monterey, Kern, Los Angeles, and Napa counties.

While not all of these detections are directly linked to wildfires, the risk of wildfire-induced mobilization of mercury into groundwater is a growing concern.

Recent Studies Indicating Mercury Contamination from Wildfires

  1. A 2015 study in the Cache Creek and Putah Creek watersheds found that wildfires increased concentrations of methylmercury (MeHg), the most toxic form of mercury in sediments, plants, and aquatic organisms.
  1. Coastal Ranges Wildfires (2022–2023):

A study published in Environmental Science & Technology examined two burned watersheds and one reference site:

  • Initial storm runoff post-fire carried suspended solids with mercury levels up to 46 times higher than the reference site.
  • Mercury was predominantly in particulate form, associated with ash and eroded soil.
  • Rapid vegetation regrowth helped reduce mercury transport within months
  1. Camp Fire (2018, Butte County)

The Camp Fire, which destroyed the town of Paradise, released toxic metals including mercury:

  • Elevated levels of lead, zinc, and mercury were detected in air samples up to 150 miles away.
  • Structural fires contributed to the release of synthetic materials containing heavy metals.
  1. Dixie Fire (2021)

While specific mercury data is limited, the Dixie Fire prompted legal and environmental scrutiny:

  • Highlighted the role of airborne pollutants and post-fire runoff in contaminating watersheds.

• Ongoing studies are assessing the long-term impacts on water quality and ecosystem health

 

How Wildfires Cause Volatile Organic Compound (VOC) Contamination

VOCs are a group of chemicals that can easily become vapors or gases. VOCs like benzene, toluene, ethylbenzene, and xylene are commonly released during wildfires due to the combustion of vegetation, building materials, plastics (e.g., PVC, HDPE) and household chemicals, especially in areas with permeable soils and shallow aquifers

These VOCs can infiltrate soil and groundwater through direct deposition from smoke and ash, leaching from burned infrastructure and debris, suction into water systems and when pressure drops during firefighting efforts. Once in the environment, VOCs can persist in groundwater due to their chemical stability and low biodegradability.

Notable Locations Indicating VOC Contamination from Wildfires

Several wildfire events in the U.S. have led to documented VOC contamination:

Paradise, California (Camp Fire, 2018): Benzene and other VOCs were found in the drinking water system, traced back to melted plastic pipes and intrusion of smoke and gases.

Santa Rosa, California (Tubbs Fire, 2017): Similar contamination was observed, with VOCs detected in water mains and service lines. The contamination was linked to the degradation of plastic pipes and the intrusion of smoke and gases into water lines during pressure loss events.

Gallinas Creek, New Mexico (Calf Canyon/Hermit Peak Fires, 2022): Post-fire monitoring showed impacts on water quality, including potential VOC presence 3.

Traditional methods for mercury analysis in soil:

Cold Vapor Mercury Analysis: Overview

As discussed, the analysis of mercury in environmental samples, such as air, water, and soil, is crucial for assessing the impact of mercury pollution and for ensuring public health and safety. The most common methods for mercury detection is cold vapor atomic absorption spectroscopy (CVAAS), which relies on the reduction of mercury ions (Hg²⁺) to mercury vapor (Hg⁰) at low temperatures. Cold vapor analysis involves two primary steps:

  1. Reduction of mercury: Mercury in environmental samples, typically present as Hg²⁺ (ionic form), is reduced to its elemental form (Hg⁰), which is gaseous.
  2. Detection of mercury: The mercury vapor is then quantified using atomic absorption spectroscopy (AAS), where the absorption of light by mercury vapor at a specific wavelength is measured, providing a direct indication of the concentration of mercury in the sample.

Cold vapor analysis is valued for its sensitivity, specificity, and relatively simple sample preparation, making it ideal for low-concentration mercury detection.

The following EPA cold vapor methods have been established for the analysis of mercury in environmental samples:

  • EPA 7470A: Mercury in Liquid Waste
  • EPA 7471B: Mercury in Solid or Semi-Solid Waste

 

Limitations and Possibilities of Interference in Cold Vapor Mercury Analysis in the Presence of Volatile Organics

While this technique has proven effective for many environmental matrices, its performance can be significantly impacted by the presence of volatile organic compounds (VOCs). Interferences stated in these methods includes “certain volatile organic materials that absorb at this wavelength may also cause interference.”

Potential Interferences from Volatile Organics in the detection of Mercury

The primary limitation in the cold vapor technique arises when volatile organic compounds (VOCs) are present in the sample matrix. VOCs are a broad class of organic chemicals that have high vapor pressure at ambient temperature, including compounds such as benzene, toluene, xylene, and various chlorinated solvents. These compounds can interfere with the cold vapor analysis in the following ways:

  1. Chemical Interference During Reduction:
    • VOCs as Reducers: Some VOCs can act as reducing agents, potentially reducing not only mercury ions (Hg²⁺) but also other elements in the sample. This can lead to a false positive result, where the mercury concentration is overestimated. For instance, VOCs containing active hydrogen atoms (such as alcohols or aldehydes) may reduce mercury ions along with other metal ions, making it difficult to distinguish mercury from other reduced species.
    • Competing Reactions: In the presence of certain organic solvents or compounds, the reaction between the sample matrix and the reducing agent (commonly stannous chloride, SnCl₂) may be disrupted. This can affect the efficiency of mercury reduction and result in incomplete or uneven mercury vapor generation, reducing the accuracy of the analysis.
  2. Physical Interference from VOCs:
    • Volatility Overlap: Many VOCs have similar vapor pressures to mercury, meaning they could be co-distilled or co-evaporated during the cold vapor generation process. This can lead to erroneous readings or contamination of the mercury signal with signals from the VOCs, complicating the analysis. In some cases, VOCs could enhance or suppress the absorption signals for mercury, leading to inaccurate quantification.
    • Matrix Effects: The presence of VOCs in the sample matrix can also alter the characteristics of the cold vapor generation system, such as the temperature or the efficiency of mercury vapor collection. Organic solvents may change the viscosity of the sample or introduce bubbles, which could interfere with the atomization or detection of mercury.
  3. Instrumental Interference:
    • Spectral Interference: Some VOCs may have absorbance or emission spectra that overlap with that of mercury. This could cause spectral interference, particularly when using atomic absorption or atomic fluorescence techniques for detection. As a result, the instrument may record signals from both mercury and the VOCs, leading to inaccurate quantification of mercury.

Analysis for Mercury by Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

Cold vapor mercury analysis remains a powerful and widely used technique for detecting mercury in environmental samples. However, the presence of volatile organic compounds poses significant challenges to the accuracy and reliability of this method. While there exists several strategies to help mitigate interferences in the cold vapor mercury analysis technique in the presence of VOCs, alternate analytical techniques should be considered.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) can be preferable to Cold Vapor Atomic Absorption Spectroscopy (CVAAS) for mercury analysis in environmental samples in the presence of volatile organic compounds (VOCs) for several important reasons. These reasons revolve around ICP-MS’s sensitivity, specificity, and ability to handle complex matrices, including those contaminated with VOCs.

The ICP-MS method measures ions produced by a radio-frequency inductively coupled plasma. Analyte species in liquid are nebulized and the resulting aerosol is transported by argon gas into the plasma torch. The ions produced by high temperatures are entrained in the plasma gas and introduced, by means of an interface, into a mass spectrometer. The ions produced in the plasma are sorted according to their mass-to-charge (m/z) ratios and quantified with a channel electron multiplier. Below are the key advantages of using ICP-MS in such scenarios:

  1. Reduced Interference from VOCs
  • Chemical and Physical Interferences: ICP-MS is much less affected by the presence of VOCs because it uses mass spectrometry to detect ions at specific mass-to-charge ratios (m/z). VOCs typically do not interfere with the mass spectrometry detection of mercury, as their molecular masses are quite different from that of mercury (Hg, m/z 202). This makes ICP-MS a more robust method in complex sample matrices containing VOCs.
  1. High Sensitivity and Low Detection Limits
  • Detection Sensitivity: ICP-MS offers exceptional sensitivity, with detection limits in the low parts per trillion (ppt) range, which is orders of magnitude better than Cold Vapor Atomic Absorption Spectroscopy (CVAAS). In environmental samples where mercury concentrations can be very low, ICP-MS provides the sensitivity needed to detect trace amounts of mercury even in the presence of background interferences, such as VOCs. CVAAS, while sensitive, is not as effective at detecting very low concentrations of mercury when the matrix is complex or when there is significant interference.
  1. Multi-element Capability
  • Simultaneous Detection of Other Elements: ICP-MS can simultaneously analyze multiple elements in a single sample, which is highly beneficial when mercury is one of several potential contaminants in an environmental sample. For example, ICP-MS can measure mercury alongside other toxic metals like lead, arsenic, and cadmium, providing a comprehensive analysis in a single run. This is particularly useful in environmental monitoring, where multiple contaminants may be present in a single sample. Cold vapor techniques, in contrast, are focused specifically on mercury and would require separate analyses for other elements, making them less efficient in complex environmental testing scenarios.
  1. Ability to Handle Complex Sample Matrices
  • Matrix Tolerance: ICP-MS is highly versatile and capable of analyzing samples with a wide range of matrices, including those that may contain VOCs, organic solvents, and other complex chemical species. The robustness of ICP-MS in handling difficult matrices (such as those with high organic content or high salinity) is a significant advantage over CVAAS.
  1. No Need for Reduction or Distillation
  • Sample Preparation: Cold vapor analysis typically requires a reduction step (e.g., using stannous chloride or other reducing agents) to convert mercury from its ionic form (Hg²⁺) to its elemental vapor (Hg⁰). This step can introduce potential interferences, particularly in the presence of VOCs. In contrast, ICP-MS does not require such a reduction step for mercury analysis. The sample is introduced into the plasma in its dissolved state, and mercury is ionized directly. This removes the need for complex sample preparation and makes ICP-MS more suitable for rapid, straightforward mercury analysis, particularly in environmental samples with challenging matrices.
  1. Quantitative Analysis in the Presence of Organics
  • Improved Quantification: While CVAAS can suffer from matrix effects in the presence of VOCs, ICP-MS’s mass spectrometric detection is more selective and precise. Even in the presence of interfering organic compounds, the ability of ICP-MS to resolve ions based on their mass-to-charge ratio allows for accurate quantification of mercury without the confounding effects of VOCs. This makes ICP-MS a more reliable method for accurate mercury quantification in complex environmental samples.
  1. High Throughput and Efficiency
  • Speed and Automation: ICP-MS is capable of analyzing a large number of samples quickly and with minimal operator intervention. It can be easily automated, making it a high-throughput option for environmental monitoring programs. On the other hand, CVAAS is often more time-consuming and requires more frequent calibration, especially in complex sample matrices. When VOCs are present, CVAAS analysis may require extra time to address potential interferences, making it less efficient compared to ICP-MS for large-scale environmental testing.

Conclusion

Utilizing an ICP-MS method is often preferred over cold vapor atomic absorption spectroscopy (CVAAS) for mercury analysis in fire impacted environmental samples potentially containing VOCs due to its superior ability to handle complex matrices, reduce interference, and provide high sensitivity with minimal sample preparation. The mass spectrometric detection offered by ICP-MS ensures accurate and reliable quantification of mercury, even in the presence of VOCs and other interferences. Furthermore, the ability to simultaneously analyze multiple elements makes ICP-MS a more versatile and efficient tool for environmental monitoring and contamination assessment. Finally, advancements in ICP-MS technology continues while Cold Vapor technology is more static.

BSK recommends EPA method 6020B for the analysis of Mercury in soils and groundwater impacted by wildfires. Acid digestion of the soil and groundwater is required prior to filtration and analysis. The acid digest can then be analyzed for Mercury along with the other California Title 22 metals.

How to Propose Projects with Confidence: Simple Steps to Stop Underselling Your Skills

/in , /by

Proposing Work Without Underselling Your Expertise

Let’s be honest—writing proposals as a Geoprofessional can sometimes feel like a special form of torture. You’re essentially saying, “Please pick me! But also, here’s exactly how much it’s going to cost you, and yes, I know my competitor may have quoted 20% less.” It’s somewhat akin to asking someone to marry you while simultaneously negotiating the prenup.

But here’s the thing: the proposal process doesn’t have to be a dance of desperation or one that cuts into a reasonable profit margin. With the right approach, you can waltz your way to winning work while maintaining a reasonable fee while doing it. Revolutionary concept, right?

Know Your Worth (And Then Add Your Margin)

First things first Geoprofessionals: we must stop treating our expertise like a commodity. You didn’t spend years learning the difference between clay and silt just to compete solely on price. Your geological knowledge, project experience, and that uncanny ability to spot potential problems before they become expensive disasters? That’s valuable stuff. Not to mention the amazing person you are and the way you focus on client relationships!  That’s worth something too!

When pricing your services, remember that clients aren’t just buying your time—they’re buying peace of mind, risk mitigation, and the confidence that comes from working with someone who is knowledgeable and is serving as part of their team. That’s worth more than the rock-bottom bidder who promises everything for nothing and delivers an inferior product and client experience.

The Art of Strategic Storytelling

Every proposal should tell a story, and that story should be: “Here’s why we’re the heroes you need for this particular project.” Generic proposals are like elevator music—forgettable and even slightly annoying. Instead, show that you actually read their RFP (shocking, we know), are familiar with projects like they are soliciting services for, and understand their specific challenges.

Did they mention tight deadlines? Talk about your project management approach and your team’s ability to deliver. Are they worried about regulatory compliance? Share that story about how you resolved a unique permitting situation. Concerned about budget overruns? Highlight your approach to budget management, transparency and collaboration with project scoping and estimating, and your track record of staying on or under budget.

The Goldilocks Principle of Proposal Length

Your proposal should be detailed enough to be useful, but not so complex that it overwhelms the reader. Nobody wants to read a novel about why you’re qualified to do a Phase I ESA. On the other hand, a two-page proposal for a complex remediation project is likely too brief and suggests that either you don’t fully understand the scope or you’re planning some creative scope creep later.

Aim for that middle ground where you provide enough detail to demonstrate competence without putting the reader to sleep.  Of course, be sure to cover all the necessary bases to avoid unnecessary risk or exposure. However, speaking in terms that anyone can understand and keeping the proposal concise by preventing the client from having to read 47 pages about soil sampling methodologies will be considered a valuable and welcomed approach.

Differentiation That Actually Matters

Saying you provide “quality work” and “excellent customer service” is like saying you breathe oxygen—it’s expected, not something that differentiates you. When a client contacts anyone who provides our services they expect a base level of technical expertise and customer service that should be standard for any consultant. So, focus on what makes you truly different. Maybe you’re the only firm in town with experience in a wide range of disciplines that are needed for a project. Perhaps you have a particularly efficient mobilization process that saves your clients money. Or maybe you’re just really, really good at explaining complex geological concepts in terms that non-geologists can understand.

Whatever it is, make it specific and make it relevant to them AND their project. “We’re different because we care” isn’t compelling. “We’re different because we’re the only firm in the region with a full-service Geotechnical Engineering and Geology team with a 98% first-pass state regulatory approval rate” is.

The Follow-Up That Doesn’t Feel Stalker-ish

Submitting your proposal and then never following up is like putting a bat and ball into a kid’s hands and never teaching them how to play the game of baseball. A thoughtful plan for follow-up shows you’re engaged and professional, not desperate. Send a brief email confirming receipt, offer to answer questions, and if appropriate, maybe share a relevant article or case study that supports what you have proposed.

The key is emphasizing your interest in being part of the client’s team.  Being helpful, not pushy. “I saw this article about similar contamination issues and thought it might be relevant to your project,” is professional engagement. “Have you made a decision yet? How about now? Now?” is how you get blocked on LinkedIn.

When to Walk Away (And How to Do It Gracefully)

Sometimes the best business decision is knowing when not to bid. If a project is clearly under-scoped, the timeline is impossible, or the client is shopping purely on price for work that requires significant expertise, it might be time to decline and point yourself in another direction politely. This isn’t giving up—it’s strategic resource allocation that is truly valuable to you, your team, and your company.

A departure can be made gracefully by saying “This project doesn’t align with our current capacity, but we’d love to be considered for future opportunities,” which maintains relationships while protecting your sanity and profitability. Plus, clients remember firms that are honest about their limitations, and that can lead to better-matched opportunities down the road.  There is truly nothing worse than overpromising and underdelivering, which can be a real consequence of accepting poor commissions.

The Long Game

Remember, every proposal is part of building your and your company’s reputation in the industry. Even when you don’t win, you want to be remembered as the firm that submitted a thoughtful, professional response that demonstrated real understanding of the project. Today’s runner-up can be tomorrow’s sole-source contractor. Sometimes those losses can even create opportunities to build a relationship with the client through a quality debrief!  So, regardless of the outcome, be confident in your approach and provide a quality proposal to your client.

The goal isn’t to win every project—it’s to win the right projects at the right price with clients who value what you bring to the table. The product will be an incredibly valuable  client base and book of business that will result in a much healthier business and significantly less stress.

Now go forth and propose with confidence. Your expertise is worth it, your clients need it, and your profit margins (and business managers) will thank you for it.

BSK Associates’ Blood Drive: A Tradition of Giving Back and Saving Lives

/in /by

Rolling Up Our Sleeves: BSK’s Commitment to Saving Lives Through Our Annual Blood Drive

At BSK Associates, giving back isn’t just part of what we do – it’s part of who we are. One of the most impactful ways we serve our communities is through our Annual Blood Drive, a long-standing tradition that brings our team together to help save lives.

Each year, our employees step away from their desks and job sites to roll up their sleeves in partnership with the Central California Blood Center. It’s a simple but powerful act of service that reflects our ongoing mission to make a positive impact where we live and work.

A Tradition of Compassion and Community

Our blood drives span many years and reflect a deeply rooted culture of generosity. From the beginning, these events have united our team around a shared goal: to support our local community in a life-saving way.

Over time, participation has grown—thanks to returning donors, new faces, and the enthusiastic support of our internal champions who help plan and organize each event. What started as a service initiative and has become a celebration of teamwork, compassion, and connection.

We’ve also proudly contributed financial donations to the Central California Blood Center, further reinforcing our commitment beyond blood donations alone.

2025: Continuing the Legacy

This year’s Annual BSK Blood Drive takes place on Friday, August 8th at our Fresno office (691 N. Laverne Ave.) from 10 AM to 1 PM. More than tradition, the event reflects our shared values of care and community support.

We’re especially excited to introduce a new thank-you for donors: “Donate a pint, get a pint!” For the first time, participants will receive a free pint of ice cream from Umpqua Dairy as a sweet reward for their life-saving generosity. It’s a fun twist that we hope encourages even more people to join us.

Whether you’re a long-time donor or considering it for the first time, we invite you to be part of this meaningful tradition.

More Than Just a Blood Drive

BSK’s commitment to community goes well beyond this annual event. From supporting local education to environmental efforts and industry outreach, we believe in creating opportunities for employees to make a difference. Our approach includes:

  • Encouraging individual volunteerism
  • Supporting office-level initiatives like food drives and clean-ups
  • Organizing firm-wide events—like our blood drive—that have a broader impact

These efforts not only benefit our communities – they strengthen our workplace culture and remind us why our work matters.

Looking Ahead

We’re proud to continue this life-saving tradition and are grateful to everyone who helps make it a success. We hope to see even more first-time donors this year and, in the years, to come.

If you’re unable to attend, we encourage you to visit your local blood center—because one donation really can save up to three lives.

BSK Associates Donates to Odyssey Learning Center in Support of Children with Autism

BSK Associates Donates to Odyssey Learning Center in Support of Children with Autism, Thanks to Employee-Driven Sponsorship Program

What happens when a company empowers its employees to give back? Amazing changes begin to take place in local communities.

BSK Associates is proud to announce that Odyssey Learning Center has been selected as the recipient of its Second Quarter Corporate Sponsorship, thanks to the heartfelt nomination from BSK field technician Taressa Jaramillo. Through this employee-driven program, BSK donates quarterly to nonprofit organizations selected by staff via a random drawing. This allows the company’s philanthropic efforts to reflect the personal passions and values of its people.

Odyssey Learning Center, located on a five-acre campus in Orangevale, California, offers specialized education and support for children diagnosed with Autism Spectrum Disorder (ASD) or exhibiting autistic-like symptoms. The school provides a structured, individualized learning environment focused on academics, independent living, communication, and vocational training—along with therapeutic services like speech, occupational therapy, and full-time behavioral support.

For Taressa, the choice was personal and deeply meaningful.

“This organization hits close to home for me,” she said. “My niece Maliyah is severely autistic and nonverbal. When my sister was exploring school options, Odyssey stood out for its caring staff, peaceful campus, and specialized services. It was exactly what Maliyah needed—and what so many families are desperately seeking.”

Taressa also shared that she worked at Odyssey for five years—an experience she describes as both eye-opening and profoundly rewarding.

“Connecting with the kids and learning how to support them as individuals helped me grow both personally and professionally. Every day, we worked to make a difference in their lives—and they made a difference in ours.”

The sponsorship reinforces BSK’s commitment to not only technical excellence in environmental, engineering, and analytical services—but also to uplifting the communities where its employees live and work.

“We are honored to support an organization that is creating life-changing opportunities for children and families,” said Renea Rangell, CEO at BSK Associates. “Taressa’s story is a powerful reminder of why our corporate sponsorship program exists: to channel our resources where they matter most—into the hands of people making a real impact.”

These quarterly sponsorships are more than just a donation—it’s a reflection of BSK’s belief that the people closest to the work are also closest to the causes that matter. By inviting employees to nominate nonprofit organizations they are personally connected to, BSK ensures its charitable giving is guided by genuine stories, lived experiences, and a true understanding of community needs.

Furthermore, these employee-driven choices create a ripple effect—bringing visibility and financial support to organizations that may not otherwise be on a corporate radar. In doing so, BSK not only empowers its team but also strengthens its ties to the communities where its employees live, work, and care deeply. It’s a model of giving that is personal, intentional, and impactful.

From supporting local nonprofits to investing in STEM education and promoting environmental stewardship, BSK Associates is proud to build stronger communities by giving back, through action, compassion, and employee-driven initiatives.
