BSK selected for on-call contract

BSK selected for on-call contract

BSK has provided the City of Fremont with on-call materials testing and special inspection services since 2016. As part of this on-going contract, #BSK has provided support to the City’s annual pavement rehabilitation projects and also directly supplemented the City’s in-house laboratory. Our initial on-call contract with the City expired at the end of 2020 and subsequently the City solicited another on-call contract Request for Qualifications for a period of up to 5 years to which BSK responded and was selected by the City for the new agreement. BSK is thankful to have the opportunity to continue supporting the City of Fremont where typical services include onsite and offsite materials sampling and testing for earthwork, concrete, and hot mix asphalt construction.

What Are PFAS?

PFAS are man-made chemicals that include Perfluorooctanoic acid (PFOA), Perfluorooctanesulfonic acid (PFOS), GenX, and several additional chemicals. In fact, PFAS are made up of more than 3,000 man-made chemicals that are largely unregulated.

The U.S. began manufacturing these chemicals during the 1940’s. In 2006, the EPA launched the PFOA Stewardship Program which eliminated the use of several PFAS chemicals. Unfortunately, the U.S. still receives these PFAS compounds from imported goods from around the world.

PFAS are a concern because they do not break down and therefore bio accumulate over time. Furthermore, food, household products, animals, drinking water, and humans have all tested positive for PFAS. In fact, research has indicated that most people have detectable amounts of PFAS in their blood. Additionally, it is believed that everyone, even those who have not consumed drinking water that has been contaminated, will have some exposure to PFAS during their lifetime.

PFAS exposure can lead to many adverse health effects in humans including (but not limited to) thyroid hormone disruption, liver and kidney toxicity,  reproductive system and developmental damage, low infant birth weights, harmful effects on the immune system, and several different forms of cancer.

BSK Provides Testing Support After Fire Devastation

Metals analysis determines extent of soil contamination after fires.

Fires of recent magnitude have caused a danger to the environment that could potentially take years to clean up. Any building that has burned to a non-salvageable degree has the potential to cause toxic pollution. Immediate concerns include materials and finishes that were used in the construction of these buildings. Most paints used until 1978 contained lead, and from the 1940s to the 1970s, PCB’s were widely added as preservatives. And, until 1990, they also contained mercury. These heavy metals were used to improve flow, durability, flexibility and ironically, to increase resistance to fire damage and moisture. When plastic is burned it also releases toxic chemical fumes (like dioxins, furans and styrene gas) into the air that is harmful for humans and the environment. Many destroyed structures had roofs that may have been shingled in asbestos and filled with treated wood that can release arsenic and chromium when burned. An incinerated television can expose heavy metals such as cadmium and lead. Even seemingly innocuous items, such as collectible antique Fiesta ware crockery, may contain radioactive uranium. Mercury can leak from old thermometers and there may be radioactive isotopes from burned-up antique crock ware, cupboards of incinerated household cleaners, and asbestos from old siding.
Cleanup crews will be looking for things like burned bottles of bleach, melted cans of paint, and corroded car batteries, which will then be tagged and removed. Samples of the surrounding soil are collected for testing, and if needed, will scrape away layers to get to clean earth, free from oil and gasoline. Heavy metals, chemicals and biological contaminants left behind demand a cleanup of extraordinary scale, before any permanent return is safe. It is only after the properties have received certification that they have been remediated that residents can begin rebuilding.
BSK Analytical has vast experience testing soil samples after devastating fires. Our laboratory routinely analyzes soils for metals on a rush basis at very low detection levels. We have automated sample digestion and preparation equipment to achieve higher throughput of samples for this purpose. Our 6 automated systems can prepare over 400 samples overnight for analysis the next morning. In addition, our state-of-the-art autosampler provides for sample introduction that greatly optimizes fast analysis on the ICP/MS without sacrificing low reporting sensitivity.
BSK’s expertise includes the ability to analyze Mercury by ICP/MS rather than the more traditional Cold Vapor Atomic Absorption (CVAA) method. We have perfected ICP/MS mercury analysis allowing for only one digestion and one analysis for the CAM 17 metals, rather than having to perform them separately. ICP/MS is a preferred method for mercury when analyzing samples from a fire site because of the potential for the presence of volatile organics such as benzene generated by melted piping. Some volatile organics can cause positive interference for mercury when analyzed by CVAA.
We are deeply saddened by the devastation felt by those in the communities that fell victim to the fires, but we are excited for the opportunity to be part of the effort to help these communities recover and rebuild.
