Current Total Dissolved Solids 1-Hour Levels

The map below shows the current highest total dissolved solids 1-hour levels measured in milligrams per liter (mg/l) for each of the river basins across Texas where total dissolved solids is measured by the TCEQ. More detailed maps showing the current 1-hour total dissolved solids levels measured at each site in a particular basin are available by clicking on the boxes on the map. These levels are based on data measured at the TCEQ's continuous water quality monitoring stations and may include data from local governments and private monitoring networks.
