This report summarizes major findings about water quality in south-central Texas that emerged from an assessment conducted between and by the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program.
Water quality is discussed in terms of local and regional issues and compared to conditions found in all 36 NAWQA study areas, called Study Units, assessed to date. To better understand timescales of water-quality change over short (daily to monthly) and long (seasonal to decadal) timescales, the U.S.
