Assessing Quantity & Quality

Groundwater provides a valuable source of drinking water for millions of people across the U.S. But as new contaminants are discovered and droughts continue to worsen, resulting in depleted aquifers, it is increasingly important to monitor the quantity and quality of available groundwater. The U.S. Geological Survey (USGS) recently updated Water Quality Products on the status of groundwater quality in the U.S.

What is the role of the USGS in surveying and monitoring groundwater quality and availability in the U.S.?

Questions for Proper Testing

Water treatment has evolved greatly over the past several years, from simple filters and water softeners to more complex treatment including new and different media, reverse osmosis, ultrafiltration and nanofiltration. A major reason behind this move forward is that more water testing is being done throughout the U.S. by public water systems, in addition to studies by the U.S. Geological Survey that map common contaminants in groundwater and surface waters such as lakes and streams.
