What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Texas has 862 active non-transient non-community water systems, 12% of the state's 7,078 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 1,192 Texas systems (17%) list purchased surface water as their primary source.
Who owns and regulates Nouryon Surface Chemistry?
EPA lists Nouryon Surface Chemistry as privately owned. The TX state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 127 of the 287 active systems in Fort Bend County (44%) are also privately owned.
Does Nouryon Surface Chemistry have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in May 2025. The violations listed here began between June 2004 and May 2025. By type: 7 public notice, recordkeeping or other, 2 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Public Notice (7 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
