Ascii grids of predicted pH in depth zones used by domestic and public drinking water supply depths, Central Valley, California

The ascii grids associated with this data release are predicted distributions of continuous pH at the drinking water depth zones in the groundwater of Central Valley, California. The two prediction grids produced in this work represent predicted pH at the domestic supply and public supply drinking water depths, respectively and are bound by the alluvial boundary that defines the Central Valley...

Data for Radium Mobility and the Age of Groundwater in Public-drinking-water Supplies from the Cambrian-Ordovician Aquifer System, North-Central USA

High radium (Ra) concentrations in potable portions of the Cambrian-Ordovician (C-O) aquifer system were investigated using water-quality data and environmental tracers (3H, 3Hetrit, SF6 , 14C and 4Herad) of groundwater age from 80 public-supply wells (PSWs).

Current Streamflow and Water-Quality Monitoring at Select Sites in the Animas and San Juan River Basins, Colorado, New Mexico, and Utah

The USGS monitors current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah, including areas below the Gold King Mine release area. These streamgages provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity.

Geochemical Composition of Urban Stormwater Runoff Within the Conterminous United States from Samples Collected in 2016-2017

These analyses provide the basic geochemical composition of urban stormwater runoff from rainwater/stormwater that does or has the potential to infiltrate groundwater from Green Infrastructure control measures. These measures are able to mimic the natural landscape with engineered designed systems to enhance stormwater infiltration to groundwater.

Increasing chloride in rivers of the conterminous U.S. and linkages to potential corrosivity and lead action level exceedances in drinking water

This study analyzed long-term trends (1992–2012) and the current status (2010–2015) of chloride, chloride-sulfate, and the Larson Ratio to investigate the short and long-term temporal variability in potential corrosivity of US streams and rivers.
