Analytical Services

BSK is your trusted source for a broad spectrum of organic and inorganic analyses for drinking water, wastewater, soils, sludges, hazardous materials and biomass fuels. 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. Our laboratory analytical services division is the preferred provider for over 950 clients including large and small municipalities, private water systems, wastewater treatment facilities, industrial dischargers, consulting engineers, biomass energy providers and private homeowners. We routinely analyze over 350 individual parameters.

BSK is accredited by The NELAC Institute (TNI) to perform environmental analyses. 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 accredited in all 6 fields of testing for drinking water, all 5 fields of testing for waste water and all 5 fields of testing for hazardous waste for Inorganics, Organics, Radiochemistry, Microbiology and Disinfection By-Products. In addition, BSK was recently certified by the U.S. Environmental Protection Agency (USEPA) to perform all analytical methods for the upcoming round of the Unregulated Contaminant Monitoring Rule (UCMR4).
