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.美国地质调查局（United States Geological Survey, USGS）国家水质计划（National Water Quality Program, NWQP）下属东南溪流质量评估（Southeastern Stream Quality Assessment, SESQA）项目采集了过滤后的水样，样本来自美国4个州内城市土地利用程度各异的流域中的59个常年性可涉水源头溪流点位（基流条件下宽度小于10米、水深小于1米）。本数据集包含采样点位位置及相关信息、分析方法信息、水样药物浓度与汇总统计数据，以及对应流域的土地利用与覆被数据和数据字典。
