How does Valco compare with other water systems in Lancaster County?
By EPA's size categories, Valco is a very small system (500 people or fewer). Lancaster County has 402 active public water systems. Its population served is well below the county average of 1,008 people per system, and accounts for less than 0.1% of the 405,283 people reported by systems filed under the county. Across Pennsylvania, the 7,217 active systems average 1,741 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Valco is well below that figure.
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. Pennsylvania has 1,026 active non-transient non-community water systems, 14% 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 Valco?
EPA lists Valco 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. 292 of the 402 active systems in Lancaster County (73%) are also privately owned.
Does Valco have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in July 2025. The violations listed here began between April 2013 and July 2025. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Trichloroethylene (6 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.
