Versar has supported more than a dozen Maryland and Virginia Phase I and Phase II MS4 jurisdictions by providing sampling, data collection, data analysis, and report preparation. Our services are tailored to meet the specific needs of individual permits, Chesapeake Bay Program TMDL targets, and Chesapeake Trust Fund monitoring requirements. We have worked on illicit discharge detection; hotspot investigations; storm runoff sampling; storm water treatment performance assessments; geomorphic assessments; biological sampling; and annual report and required database preparation. Versar's an in-house weather center that provides accurate storm prediction to researchers, which enables cost-effective sample collection.
