Since 1982, members of our staff have supported EPA’s Office of Pesticide Programs. As part of this contract, our staff assess environmental and human health impacts on anthropogenic chemicals. The agricultural industry is critical to food and textile production, it is a large contributor to the U.S. economy. Not only does the industry provide food and materials for the U.S., it also provides products that are high-demand exports for other countries. Our dedicated staff help support this important industry by helping to ensure products used by the agricultural industry aren’t adversely impacting humans, animals, and the surrounding environment.

Our work consists of
- Evaluating pesticide residues in food and feed crops as well as livestock
- Evaluating mammalian toxicity data for agricultural and industrial chemicals
- Determining critical end-points, no-observed-adverse-effect levels and lowest-observed-adverse-effect, reference doses or reference concentrations, and cancer values
- Assessing risk and analyzing weight of evidence
- Evaluating chemical toxicity to non-target species
- Determining no-observed-adverse-effect levels and lowest-observed-adverse-effect levels
- Monitoring movement, metabolism, and degradation of chemicals in the environment
- Evaluating regulatory compliance and quality assurance
For 41 years our staff have been providing these services to EPA’s Office of Pesticide Programs, making this contract our longest client relationship!

World Seagrass Day!
Seagrasses are critical to coastal and ocean ecosystems, protecting coastlines from erosion, stabilizing ocean sediment, and improving water clarity. They provide food and shelter for aquatic life, including seahorses, turtles, thousands of species of fish, and more. In addition, they are amazing carbon sequesters, meaning they absorb atmospheric carbon reducing greenhouse gases. On World Seagrass Day, we…
Training Citizen Scientists on Identifying Harmful Phytoplankton Within their Communities
Since 2018, CSS employee owners have provided support to NOAA’s Phytoplankton Monitoring Network (PMN) program, which is managed out of NOAA’s National Centers for Coastal Ocean Science (NCCOS). NOAA’s Phytoplankton Monitoring Network provides a highly valued bridge between the public and aquatic ecosystem researchers. Through this program, citizen scientists collect water samples from their designated…
Remediating Soil Surrounding Abandoned Mines
CSS employees have been providing field, lab, and horticultural support for the Environmental Protection Agency’s efforts to develop and test methods for the remediation and revegetation of contaminated soils around selected abandoned mines in the western United States. One of the promising approaches is to incorporate biochar into the soil. Using biochar helps effectively adsorb trace metals and reduce their…
