Romanok, K.M., Bradley, P.M., and Journey, C.A., 2020, Concentrations of Pharmaceutical Contaminants and Their Predicted Effects from a Multi-Regional Assessment of Wadeable USA Streams: U.S. Geological Survey data release,


Human-use pharmaceutical compounds were analyzed at the U.S. Geological Survey, National Water Quality Laboratory, Denver, Colorado, in wadeable streams in 4 Regional Stream Quality Assessments: Northeast (NESQA), Southeast (SESQA), Pacific Northwest (PNSQA) and California (CSQA). Multiple (with few exceptions) samplings occurred at each site, during base flow, between 2014 and 2017. Sites were located in the headwaters of perennial, wadeable streams in urban and agricultural watersheds. Site selection and methodology for each assessment can be found in Van Meter and others (2015), Sheibley and others (2015), Van Meter and others (2017), Coles and others (2019), Van Meter and others (2016), Journey and others (2015), and Van Meter [...]

This data set provides the maximum and median concentrations for human-use pharmaceutical compounds analyzed in perennial, wadeable streams in four regions across the USA, with varying amounts of urban and agricultural land use. Reported maximum and median results were analyzed using a high-throughput screening data in Toxicity Forecaster (ToxCast tm; see supplemental information for more information). Spearman Rank Correlation statistics are also presented.
