CSS scientists supporting the Environmental Protection Agency’s Office of Pesticide Programs are reviewing modeling data that evaluates the potential for transfer of chemical residues from pregnant and nursing  animals to fetuses and infants. The vast majority of data come from pharmaceuticals, but staff are reviewing some data from pesticides and other environmental contaminants as well. Staff are reviewing the data for measured concentrations in maternal blood and milk as well as fetal tissues in laboratory animals and humans. The objective of this work is to better understand the various models being developed and use this modeling data to help refine risk assessment for pesticides.

An Approach to Assessing Laboratory Space 

CSS employee owners were part of a team of scientists at the National Institutes of Health who developed an approach to evaluating new laboratory space to determine if the space will fit operational needs. This concept, titled The BaseLINE Approach, combines traditional safety processes with additional safety and environmental factors to assess before operations begin.…

Assisting With Maui Wildfire Recovery

As part of our support to U.S. Environmental Protection Agency (EPA) Region 9 Superfund Technical Assessment & Response Team (START)—for which we are subcontracted through Weston Solutions, Inc.—CSS employee owners have been on-site in three-week rotations to assist throughout the rigorous recovery process.

Over 2000 River and Stream Samples Analyzed 

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…
