How does Oasis Property Owners Association compare with other water systems in Kern County?

By EPA's size categories, Oasis Property Owners Association is a very small system (500 people or fewer). Kern County has 327 active public water systems. Its population served is well below the county average of 3,140 people per system, and accounts for less than 0.1% of the 1,026,649 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active community water system reports serving 6,703 people, so Oasis Property Owners Association is well below that figure.

What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. California has 2,997 active community water systems, 40% of the state's 7,479 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.

The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 263 of the 327 active systems in Kern County (80%) are also privately owned.

Does Oasis Property Owners Association have drinking water violations?

Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in October 2024. The violations listed here began between January 2017 and October 2024. By type: 10 contaminant level above the legal limit, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Arsenic (10 of them). EPA lists 10 as archived and 2 as unaddressed.
