Summary

Brackish groundwater (BGW), defined for this assessment as having a dissolved-solids concentration between 1,000 and 10,000 milligrams per liter is an unconventional source of water that may offer a partial solution to current (2016) and future water challenges. In support of the National Water Census, the U.S. Geological Survey has completed a BGW assessment to gain a better understanding of the occurrence and character of BGW resources of the United States as an alternative source of water. Analyses completed as part of this assessment relied on previously collected data from multiple sources, and no new data were collected. One of the most important contributions of this assessment was the creation of a database containing chemical [...]

Purpose

This dataset was compiled for the purpose of assessing the geochemistry of brackish groundwater across the United States and its territories. Please note that there is a related dataset (https://doi.org/10.5066/F72F7KK1) containing dissolved-solids data that was used for assessing the distribution of brackish groundwater across the United States and its territories.
