Target chemical concentrations of mixed-organic compounds and microbiological indicators in tapwater, Montana, 2024
This data release reports the concentration results for organic compounds (disinfection byproducts [DBP], pesticides, per- and polyfluoroalkyl substances [PFAS], pharmaceuticals and volatile organic compounds [VOC]), cyanotoxins, microbiological indicators, as well as radon-222 analyzed in samples collected from private well and public supply sourced tapwater samples from a community in Montana. A total of 26 samples were collected, plus one quality-control field blank, from 18 residences with private wells and 8 locations who receive their water from public supply sources. Pesticide and DBP compounds were analyzed at the U.S. Geological Survey (USGS) Organic Chemistry Research Laboratory in Sacramento, California; radon-222, PFAS and VOC were analyzed at the USGS National Water Quality Laboratory in Denver, Colorado; pharmaceutical compounds were analyzed at the USGS Organic Geochemistry Research Laboratory in Lawrence, Kansas; microbiological indicators were analyzed at the USGS Michigan Bacteriological Research Laboratory in Lansing, Michigan. Estrogenicity samples were analyzed at the USGS Eastern Ecological Science Center, Leetown, West Virginia.
Trace elements and rare earth elements were also analyzed for this study. The results and associated information can be found here: Schreiner, M.L., Romanok, K.M., Bradley, P.M., Smalling, K.L., Meppelink, S.M., McCleskey, R.B., and Roth, D.A., 2024, Concentration results for inorganic constituents in discrete tapwater samples, Montana, 2024: U.S. Geological Survey data release, https://doi.org/10.5066/P1DQ7ZFQ.
