National Water-Quality Assessment Program
South-Central Texas NAWQA

The study unit comprises the Nueces, San Antonio, and Guadalupe River Basins in Texas.  The 1996–2004 assessment involved only the upper parts of the basins.  The upper parts of the basins contain the watersheds of streams that recharge the Edwards aquifer, and the Edwards and Trinity aquifers, which were the primary focus of the assessment.
