Field and laboratory environmental measurement methods

The U.S. Geological Survey (USGS) Toxic Substances Hydrology Program develops field methods to measure a wide range of environmental properties, and develops approaches and protocols used to assess or characterize contamination.

The Program also develops laboratory analytical methods to measure a wide variety of chemicals in environmental media.

Processing samples in a lab
Laboratory processing of solar-distilled plant water to remove constituents that can interfere with subsequent tritium analysis. Interference removal is accomplished by passing the plant water through a filter and a graphite-based solid-phase extraction column -- from the Detecting Tritium in Plants Photo Gallery
