The demand for brackish groundwater is likely to grow as fresh groundwater resources are depleted, especially in parts of the country that are projected to have hotter and drier climates in the future.  The most recent national assessment of brackish groundwater resources in the United States was conducted by the U.S. Geological Survey (USGS) in the 1960s on the basis of data from about 1,000 wells (Feth et al., 1965).  Since that time, substantially more hydrologic and chemical data have been collected by various entities.  The USGS is compiling many of those data for an updated national assessment of brackish groundwater resources.  Although brackish groundwater occurs at depth nationwide, its availability and value depend on a combination of physical and chemical characteristics of the resource.  Chemical factors include chemical requirements of the proposed use, chemical characteristics of the resource, and treatment technologies to make the resource compatible with the use.  This presentation will discuss relations between these three chemical factors.
