How does Konocti Shores compare with other water systems in Lake County?

By EPA's size categories, Konocti Shores is a very small system (500 people or fewer). Lake County has 81 active public water systems. Its population served is well below the county average of 895 people per system, and accounts for 0.4% of the 72,454 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 Konocti Shores 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. 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.

Who owns and regulates Konocti Shores?

EPA lists Konocti Shores 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. 60 of the 81 active systems in Lake County (74%) are also privately owned.

Does Konocti Shores have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2019. The violations listed here began between October 1983 and July 2019. By type: 7 monitoring and reporting, 4 public notice, recordkeeping or other and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (5 of them). EPA lists 8 as resolved and 4 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.
