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.

The software allows for the acquisition, visualization, storage, and field interpretation of aquifer test data. Because of the automated data collection, near real-time estimates of hydraulic properties of the test interval can be obtained
