How does Hillcrest MHP compare with other water systems in Oklahoma County?
By EPA's size categories, Hillcrest MHP is a very small system (500 people or fewer). Oklahoma County has 113 active public water systems. Its population served is well below the county average of 7,828 people per system, and accounts for less than 0.1% of the 884,508 people reported by systems filed under the county. Across Oklahoma, the 1,254 active systems average 2,907 people each. Nationally, the average active community water system reports serving 6,703 people, so Hillcrest MHP 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. Oklahoma has 864 active community water systems, 69% of the state's 1,254 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 701 Oklahoma systems (56%) list groundwater as their primary source.
Who owns and regulates Hillcrest MHP?
EPA lists Hillcrest MHP as privately owned. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 93 of the 113 active systems in Oklahoma County (82%) are also privately owned.
Does Hillcrest MHP have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in October 2024. The violations listed here began between May 1998 and October 2024. By type: 9 monitoring and reporting, 1 reporting, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 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.
