Continuous Water Quality Monitoring Network
The TCEQ continuously monitors water quality parameters at stations in selected watersheds throughout Texas. Data is transmitted to the TCEQ and is reported at “near real time.” Data from these monitors are not instantaneously available, but are posted on the Web as soon as the data are received and processed. The data are preliminary until validated by agency staff.
