How does Houston Sunoco compare with other water systems in Washington County?
By EPA's size categories, Houston Sunoco is a very small system (500 people or fewer). Washington County has 26 active public water systems. Its population served is well below the county average of 1,750 people per system, and accounts for less than 0.1% of the 45,508 people reported by systems filed under the county. Across Pennsylvania, the 7,217 active systems average 1,741 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Houston Sunoco is well below that figure.
What does “transient non-community water system” mean?

Pennsylvania has 4,429 active transient non-community water systems, 61% of the state's 7,217 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,632 Pennsylvania systems (92%) list groundwater as their primary source.
Who owns and regulates Houston Sunoco?
EPA lists Houston Sunoco as privately owned. The PA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 13 of the 26 active systems in Washington County (50%) are also privately owned.
Does Houston Sunoco have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2023. The violations listed here began between December 1979 and January 2023. By type: 3 required treatment not met, 3 monitoring and reporting, 2 reporting, 2 public notice, recordkeeping or other, 1 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 10 as resolved and 2 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.
