Concentrations of organic and inorganic constituents in tapwater samples from California in 2020-21 (ver. 3, September 2022)

Metadata Updated: October 29, 2023

This dataset contains the trace elements, cations, anions, disinfection by-products, per- and polyfluoroalkyl substances (PFAS), pharmaceutical and pesticide concentration results for the tapwater study conducted in California, November, 2020 through May, 2021. Trace elements, cations and anions were analyzed at the U.S. Geological Survey Redox Chemistry Laboratory in Boulder, Colorado. The disinfection by-product compounds were analyzed at the U.S. Geological Survey Organic Chemistry Research Laboratory in Sacramento, California. Concentration results for PFAS, as well as surrogate percent recovery information, were analyzed at the National Water Quality Laboratory (NWQL) in Denver, Colorado, and were added in version 2.0. Conentration results for pharmaceutical and pesticide compounds, analyzed at the NWQL, were added in version 3.0.
