Review of Trace-Element Field-Blank Data Collected for the California Groundwater Ambient Monitoring and Assessment (Gama) Program, May 2004-January 2008 - Usgs Scientific Investigations Report 2009-5220 (Paperback)

Trace-element quality-control samples (for example, source-solution blanks, field blanks, and field replicates) were collected as part of a statewide investigation of groundwater quality in California, known as the Priority Basins Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Priority Basins Project is being conducted by the U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (SWRCB) to assess and monitor the quality of groundwater resources used for drinking-water supply and to improve public knowledge of groundwater quality in California.
