USGS Publishes National Brackish Groundwater Assessment

Brackish Groundwater in the United States

USGS has published a new study that suggests brackish groundwater could help stretch limited freshwater supplies. This study found that the amount of brackish groundwater underlying the country is more than 800 times the amount currently used each year. With issues like drought, groundwater depletion, dwindling freshwater supplies, and demand for groundwater expected to continue to rise, understanding brackish groundwater supplies can help determine whether they can supplement or replace taxed freshwater sources in water-stressed areas. Although this assessment can’t answer all of the questions related to sustainable use, it represents a starting point for identifying the gaps in our knowledge and for directing research to locations where further study would be most beneficial.
