How does Theos compare with other water systems in Summit County?

By EPA's size categories, Theos 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. Across Ohio, the 3,854 active systems average 2,767 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Theos is well below that figure.

What does “transient non-community water system” mean?

A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Ohio has 2,282 active transient non-community water systems, 59% 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 Theos?

EPA lists Theos 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. 180 of the 193 active systems in Summit County (93%) are also privately owned.

Does Theos have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in February 2026. The violations listed here began between January 2012 and February 2026. By type: 6 monitoring and reporting, 3 monitoring, 2 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 of them). EPA lists 9 as resolved, 2 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.
