This USGS map shows the number of PFAS detected in tap water samples from select sites across the nation. The findings are based on a USGS study of samples taken between 2016 and 2021 from private and public supplies at 716 locations. The map does not represent the only locations in the U.S. with PFAS.

Both natural and human-related metal mobilization may affect streams. In this photo drainage from a mine enters Cement Creek, near Silverton, Colorado, adjacent to a mound of iron minerals that have likely been forming naturally for thousands of years. Detailed isotopic studies may help to differentiate natural and human-related contamination. 

Draining mines provide consistent discharge and have elevated rare earth element concentrations, potentially providing opportunities for direct metal production.

Soil cores are collected and sectioned to characterize soil properties, abundance of metals, and fallout radionuclides which can be used to characterize rates of mixing of particles in soil.
