How does Deer Lake Mobile Park compare with other water systems in Geauga County?
By EPA's size categories, Deer Lake Mobile Park is a very small system (500 people or fewer). Geauga County has 228 active public water systems. Its population served is well below the county average of 267 people per system, and accounts for less than 0.1% of the 60,890 people reported by systems filed under the county.

Nationally, the average active community water system reports serving 6,703 people, so Deer Lake Mobile Park is well below that figure.
What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. 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 Deer Lake Mobile Park?
EPA lists Deer Lake Mobile Park as privately owned. The OH state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 214 of the 228 active systems in Geauga County (94%) are also privately owned.
Does Deer Lake Mobile Park have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2011. The violations listed here began between September 2010 and December 2011. By type: 12 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 10 as archived and 2 as resolved. 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. 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.
