Additional Information - Organic Chemistry Branch:

The branch is responsible for analyzing environmental samples (surface and ground water, soil, sediment, UST) for semi-volatile and volatile organic compounds, including herbicides and pesticides. These organic parameters are analyzed using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) instrumentation. Detection levels are at the parts per billion and parts per trillion levels.

The branch's clients include DWR offices and programs, the Division of Waste Management's Underground Storage Tank (UST) section, universities, and federal agencies (USGS, Fish & Wildlife).
