Mismatch lensAtlas TX · county intelligence, water evidence, field missions
Texas county evidence, mapped and made usable.
Atlas TX turns fragmented public records into a map-first investigation system for counties, permits, water risk, operators, and field verification. Start on the map, drill into the evidence, and carry the workflow into Android missions.

What does Atlas TX know about an address?
Type a Texas address. Atlas TX resolves it to a county and surfaces public drinking-water risk, environmental burden, regulated facilities, and governance signals. Geocoded by the U.S. Census Bureau.

Have a water test strip? Add it to the map.
Photograph any pool, well, or tap-water test strip and Atlas reads the bands client-side. Submissions populate a separate community-observation layer — never the regulated water-risk score. You stay in control of what gets shared.

Texas water system primer
Texas gets water from above-ground rivers and reservoirs and below-ground aquifers. The hard part is not just finding water — it is managing treatment, delivery, drought pressure, flood shocks, and county-to-county imbalance.

Open full guide →Where Texas water comes from
Texas runs on two main sources: surface water from rivers and reservoirs, and groundwater from aquifers like the Edwards, Trinity, Carrizo-Wilcox, Gulf Coast, and Ogallala.
How water moves
Rain refills rivers, lakes, and aquifers. Utilities and districts withdraw, treat, deliver, collect wastewater, then either discharge treated water back to rivers or reuse it.
Who manages it
Texas has no single statewide water system. TWDB plans, TCEQ regulates, and river authorities, groundwater districts, utilities, and water districts run the local supply chain.
Why risk varies by county
Water stress depends on drought, reservoir storage, aquifer levels, flood damage, treatment capacity, infrastructure age, growth, and upstream-downstream dependence — not just whether water is nearby.
Visual explainer
Surface water
Water stored or flowing above ground in rivers, lakes, reservoirs, and streams. This is the backbone for many larger Texas cities and regional systems.
Visual explainer
Groundwater
Water pumped from underground aquifers such as the Edwards, Trinity, Carrizo-Wilcox, Gulf Coast, and Ogallala. It is critical for rural systems, wells, and fast-growing edge communities.
