The Regional San Environmental Laboratory has been in operation at the Sacramento Regional Wastewater Treatment Plant (SRWTP) since 1982. The laboratory employs trained, professional environmental scientists and technical staff committed to providing quality services to meet both routine and challenging analytical needs for studies or monitoring programs.
Our goal is to consistently provide our customers with reliable, high‑quality environmental laboratory services. In order to achieve this objective, we maintain close working relationships with our customers and offer manageable solutions tailored to meet individual customer or program needs.
In addition to providing the standard services (including trace metals, organics, conventional chemistry, bacteriological, microbiological and toxicological analysis), the laboratory also conducts field monitoring and sample collection of ground waters and monitors the water quality of the Sacramento and American Rivers around the Sacramento metropolitan area. To accomplish this task, the laboratory owns the Guardian, a 27-foot, all-weather aluminum boat. At least once a week, a laboratory boat crew travels the river, collecting water samples and performing water quality measurements of the river at various locations.
