Summary

This data release documents water-quality data collected from April 2010 through December 2016 by the U.S. Geological Survey in cooperation with the San Antonio Water System from across the San Antonio segment of the Edwards aquifer with particular emphasis on nutrients and pesticides. Additional data regarding inorganic compounds and selected stable isotopes were obtained to provide a geochemical framework for characterizing source inputs and observed chemical changes during periods of hydrologic transition. Water-quality data were collected from surface-water and groundwater sites representing rural and urban land cover types. Data were obtained from unconfined wells in the recharge zone to characterize the rapid changes in water-level [...]

Purpose

The purpose of this data release is to document water-quality data collected for the Edwards Aquifer Recharge Zone project from April 2010 through December 2016. These data can be used by scientists and water-resource professionals to better understand sources, transformations and fate of natural and anthropogenic constituents in the Edwards aquifer.
