Methodology and public data sources

How Groundwater Assessment evaluates Texas aquifers, monitoring wells, and submitted driller reports.

Back to the Texas assessment

How a property is evaluated

The application locates the selected Texas property, checks mapped aquifer boundaries, and searches nearby Texas Water Development Board records. It separates repeated groundwater measurements from one-time construction records so unlike observations are not presented as the same kind of evidence.

Groundwater Database monitoring wells

GWDB records provide aquifer classifications and repeated water-level observations. An assessment is offered only when enough aquifer-specific, publishable observations support the local calculation.

Submitted Driller's Reports

SDR records may add well depth, casing, screen, pump, lithology, yield, and construction-day water-level details. Driller-submitted coordinates and attributes may not be state-verified, and a construction-day reading is not treated as a current measurement.

Aquifer boundaries and elevation

TWDB major and minor aquifer boundaries provide geologic context. Generated reports may use USGS 3DEP land elevation where needed to compare hydraulic-head evidence.

Eligibility and limitations

The address and evidence check happens before checkout. If the available public records cannot support an assessment, the payment form does not open. Results describe public-data evidence near a property and do not replace a licensed well inspection, onsite water-level measurement, pump test, water-quality test, or professional engineering or geoscience advice.
