We assist our communities to protect the environment by helping those in charge of our natural resources ensure they meet the strict standards set by regulators.
Environmental Analysis
BSK is accredited by The NELAC Institute (TNI) to perform environmental analyses in California, Washington, Oregon, Nevada and Hawaii. Our TNI accreditation program (based on ISO 17025) relies on our rigorous quality system that includes more stringent and comprehensive standards than non-TNI laboratories. BSK is California ELAP accredited in all 6 fields of testing for drinking water, all 5 fields of testing for non-potable water and all 8 fields of testing for solids and hazardous waste.

Our certified inspectors work as an extension of the project team, providing independent verification that critical construction elements are installed correctly and perform as intended.
Materials Testing
BSK provides comprehensive Materials Testing services that support quality assurance and regulatory compliance for infrastructure and building projects. Our testing services verify that construction materials meet project specifications, applicable standards, and agency requirements—reducing risk and supporting long-term performance from earthwork through final construction.
Geophysical
BSK Associates provides geophysical services that help clients better understand subsurface conditions while minimizing disruption to active project sites. Using non-invasive technologies, our team collects high-quality subsurface data that supports informed engineering, environmental, and construction decisions. Whether identifying buried utilities and infrastructure before excavation, evaluating unknown subsurface features (e.g. underground storage tanks, landfills, drums, wells, etc.) or supplementing geotechnical investigations, our geophysical services improve project planning, reduce uncertainty, and help manage risk.
