Monitoring Air Quality in California’s San Joaquin Valley
CSS employee owners supported the deployment and operation of the U.S. Environmental Protection Agency (EPA) air quality monitoring trailer (WEAVE COM – Western Enhanced Air quality VEhicle for COmmunity Monitoring) in California’s San Joaquin Valley in during late fall and early winter of 2024. Elevated particulate matter (PM2.5) is frequently found throughout the valley during the wintertime when thermal inversions trap pollution. Instruments on the trailer measure criteria air pollutants, other airborne contaminants and the chemical composition of particulate matter. The mobile lab allows scientists to collect atmospheric data to fill in gaps between existing fixed air quality monitoring stations to help identify sources and types of atmospheric PM2.5. CSS staff helped set up the trailer at the deployment site, conducted daily quality control checks on multiple instruments, and supported instrument operations throughout the deployment.

Quality Assurance Audit Reports
Since 1985 we’ve supported the National Institute of Environmental Health Sciences and have provided more than 1,600 quality assurance audit reports that the client has used to assess the quality of toxicology studies they sponsor. Over the last year our employee owners reviewed several studies involving per- and polyfluorinated substances (PFAS) compounds, or “forever chemicals”,…
Organizing National Mussel Watch Program Sample Collection Missions
Established in 1986, NOAA’s National Mussel Watch Program has been systematically monitoring nearly 600 chemical contaminants (including legacy organic contaminants, trace metals, and contaminants of emerging concern) and biological indicators for the establishment of baseline contamination levels in coastal waters around the U.S., including the Great Lakes, Puerto Rico, and U.S. Virgin Islands.
