Summary

Located in south-central Texas, the Geronimo Creek and Plum Creek watersheds have long been characterized by elevated nitrate concentrations. From April 2015 through March 2016, an investigation was done by the U.S. Geological Survey, in cooperation with the Guadalupe-Blanco River Authority (GBRA) and the Texas State Soil and Water Conservation Board (TSSWCB), to assess nitrate (as nitrogen) concentrations and to document possible sources of elevated nitrate as nitrogen in these two watersheds. Water-quality samples were collected from 20 groundwater, spring, and stream sites across the two watersheds, along with precipitation samples and wastewater treatment plant (WWTP) effluent samples from the Plum Creek watershed. Stream, spring, [...]

Purpose

The purpose of this data release is to document water-quality and chemical loading data collected for the Plum Creek Isotopes project in the Geronimo Creek and Plum Creek watersheds from April 2015 through March 2016. Water-quality data were collected from stream, spring, and groundwater sites from April through October 2015 (PlumCreek_QWData.txt). Additional data from a bulk precipitation collector and five wastewater treatment plants (WWTPs) located in the Plum Creek watershed also were collected from June 2015 through March 2016 and in April 2015, respectively (PlumCreek_QWData.txt). Quality-assurance data collected June 2015 through March 2016 also is included (PlumCreek_QAData.txt). Data on mean daily nitrate concentrations and effluent discharge values (variously dated, 2008-16) provided by the GBRA were used to calculate the effluent discharge contribution to the Plum Creek watershed (PlumCreek_WWTPLoads.txt).
