Every five years teams supporting U.S. Environmental Protection Agency’s National Aquatic Resource Survey—consisting of tribal, state, and federal partners—collect samples from over 2000 river and stream reaches throughout the United States. CSS analytical chemists support this effort by processing the samples and then analyzing them for various chemicals to help characterize their water quality.  The data are available at the U.S. EPA National Aquatic Resource Survey website where more information is provided on this program.

Assisting with Design and Validation of Mobile Chemical Analysis Laboratory

Portable High-throughput Integrated Laboratory Identification System (PHILIS) is the Environmental Protection Agency’s (EPA) suite of mobile laboratories designed to provide on-site analysis of chemical agents. CSS employee owners support the PHILIS team with on-site responses and chemical analysis. CSS PHILIS teams recently supported the technical design and integration of state-of-the-art emergency response mobile laboratory units engineered for the rapid detection and quantification of hazardous materials. CSS PHILIS teams in…

Installing Environmental Monitoring Stations

Our field crews installed/updated two environmental monitoring stations in remote locations in the Pacific Northwest. Multiple types of sensors were installed including air and soil temperature, precipitation, soil moisture and soil redox potential. These stations provide data for designing and evaluating soil remediation projects for U.S. Environmental Protection Agency’s Office of Research and Development. Installing…
