How does Oak Knoll Estates compare with other water systems in Summit County?
By EPA's size categories, Oak Knoll Estates is a very small system (500 people or fewer). Summit County has 193 active public water systems. Its population served is well below the county average of 2,390 people per system, and accounts for less than 0.1% of the 461,353 people reported by systems filed under the county.

What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. Ohio has 1,028 active community water systems, 27% of the state's 3,854 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,446 Ohio systems (89%) list groundwater as their primary source.
Who owns and regulates Oak Knoll Estates?

Does Oak Knoll Estates have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2025. The violations listed here began between October 2015 and April 2025. By type: 7 public notice, recordkeeping or other, 4 monitoring and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (4 of them). EPA lists 7 as resolved, 4 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
