Nationally, the average active non-transient non-community water system reports serving 430 people, so Southmill Champs 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.

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 Southmill Champs?
EPA lists Southmill Champs 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. 173 of the 254 active systems in Chester County (68%) are also privately owned.
Does Southmill Champs have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in January 2023. The violations listed here began between April 2013 and January 2023. By type: 7 monitoring and reporting, 2 contaminant level above the legal limit, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Endothall (2 of them). EPA lists 9 as resolved and 3 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.
