How does Little River Inn compare with other water systems in Mendocino County?

By EPA's size categories, Little River Inn is a very small system (500 people or fewer). Mendocino County has 144 active public water systems. Its population served is well below the county average of 576 people per system, and accounts for 0.1% of the 82,868 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Little River Inn is well below that figure.

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

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. California has 1,466 active non-transient non-community water systems, 20% 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.

Who owns and regulates Little River Inn?

EPA lists Little River Inn as privately owned. 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. 98 of the 144 active systems in Mendocino County (68%) are also privately owned.

Does Little River Inn have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in September 2008. The violations listed here began between December 1983 and September 2008. By type: 10 public notice, recordkeeping or other, 1 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 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.
