The facility data presented are refreshed weekly and the water quality monitoring data is refreshed bi-annually The WQI plots water monitoring locations and compares the values observed at these locations to a criteria or threshold.

Datasets cover drinking water quality, loan and grant information, unregulated contaminants, and more Levels listed are for the range of the total of all PFAS detected at the time of the tests and do not reflect whether a water system is treating the water to reduce levels The Water Quality Indicators (WQI) is a screening tool that makes it easy to identify pollutant hotspots based on water quality monitoring data from the U.S
USGS Groundwater News and Highlights, June 1, 2020. There are 2,394 sites that reported PFAS via UCMR 5, as of October 2024. Current and historical data presented in the WQI can be downloaded from the WQI Data Downloads Folder.

Under SDWA, EPA sets standards for drinking water quality and oversees the states, federally-recognized tribes, and territories that implement the drinking water program Drinking-water exposures to per- and poly-fluoroalkyl substances (PFAS) are a national concern, however, there is limited information on PFAS in residential tapwater at the point-of-use, especially from private-wells.
