Pharmaceutical contaminant concentration and watershed geospatial land-use/land-cover data for small wadeable streams in the Piedmont ecoregion of the USA assessed during the Southeastern Region Stream Quality Assessment during April through June 2014 Filtered water samples were collected by the USGS National Water Quality Program (NWQP) Southeastern Stream Quality Assessment (SESQA) from 59 perennial, wadeable (less than 10 m width and 1 m depth at base-flow) headwater stream sites in watersheds with varying degrees of urban land use in four states. Dataset includes sample site locations and information, analytical method information, water sample pharmaceutical concentrations and summary statistics, and corresponding watershed land-use-land-cover data and data dictionary.

Bed material samples were analyzed for radionuclides (7Be, 210Pbex, 137Cs) and pesticides (bifenthrin and DDE); suspended sediment for radionuclides (7Be, 210Pbex, 137Cs): and cropland top soil was analyzed for 210Pbex and 137Cs. Data set includes only those data specifically discussed in a Journal of Environmental Management entitled, Sources and ages of fine-grained sediment to streams using fallout radionuclides in the Midwestern United States, by Allen C....
