Where this answer comes from.
Each of these has its own page naming the office that publishes it, how often it updates, and what it cannot answer. Rebuilt from the ParcelOps source directory on September 9, 2026.
EPA Drinking Water (SDWIS)
Which public drinking water systems report service to a county, and what each one has been cited for.
PUCT Texas Water & Sewer Service Areas
Which Texas utility is obligated to serve a point with retail water or sewer, and whether that boundary is contested.
USGS Water Observations
USGS streamflow, stage, site, daily-value, water-quality, and groundwater observations.
Would answer this, not connected yet.
These sit in the same part of the ParcelOps directory and are not live, so they add nothing to the answer above today. They are named because a page that hides the unfinished half of itself is the thing this whole family is arguing against: FCC Broadband Availability.
Where this stops.
The part a search result will not tell you, and the part worth reading before this answer goes into a decision.
- City and zip searches fall back to the address on a system’s administrative record, which is a mailing address and is not verified as a service area. Texas publishes no city or zip rows in the geographic file at all, so county is the only reliable cut there.
- A violation is a compliance record against a system, sometimes for monitoring or reporting rather than for a contaminant. It is not a reading from a tap and not a statement about the water in one house today.
- Private wells are not public water systems and are absent from this file entirely, along with everything about their water quality.
- Lead service line inventories and the annual consumer confidence report are separate publications held by the utility, and they are the documents that describe what arrives at a tap.
What people ask next.
The system serving my county has violations. Is the water unsafe?
It depends on what kind, and the record says which. A large share of recorded violations are monitoring and reporting failures, meaning a required sample or report was late or missing, which is a compliance problem rather than a contaminant finding. Health based violations are a different category and are labeled that way. Read the violation type and the compliance period before reading the count.
How do I find out which system actually serves my house?
Look at a water bill, or call the utility or the state primacy agency. In Texas that is the environmental quality commission. This answer narrows a county to a short list of candidates with their identifiers and contacts, which is the part that takes an afternoon otherwise. Resolving the parcel to one system is a phone call this data cannot make.
Questions people ask alongside this one.
What environmental records exist for this site?
Federal environmental records are organized around regulated facilities, not parcels. Permits, inspections, violations, and emissions near an address, tied together by identifier.
Who do I call before digging?
Call 811 before you dig, in every state, free. What a public record screen can show you before that call, and why marks on the ground only come from a locate.
Is there a pipeline near this property?
Mapped hazardous liquid and gas transmission lines near a coordinate with the operator on each, plus county mileage. Why the public map is generalized on purpose.
Will a tall structure here need FAA review?
Screen a coordinate and a proposed height against published airports, runways, obstacles, and class airspace. Why a clear screen is not a determination.
What census tract is this address in?
Federal program designations are published by census tract, not by address. How to resolve an address to its state, county, tract, and block codes, and why the vintage matters.
Is this property in a flood zone?
A flood zone answer is a letter read off a specific FEMA map panel with an effective date. What each zone means, and why outside a zone is not the same as safe.
The lanes this question belongs to.
A lane page lists every source that kind of work reads, not only the ones behind this question, and states where the whole lane stops.
