How does Lakeside Manor compare with other water systems in Jefferson County?

By EPA's size categories, Lakeside Manor is a very small system (500 people or fewer). Jefferson County has 92 active public water systems. Its population served is well below the county average of 2,034 people per system, and accounts for less than 0.1% of the 187,106 people reported by systems filed under the county. Across Missouri, the 2,943 active systems average 2,049 people each. Nationally, the average active community water system reports serving 6,703 people, so Lakeside Manor 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. Missouri has 1,612 active community water systems, 55% of the state's 2,943 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,521 Missouri systems (86%) list groundwater as their primary source.

Who owns and regulates Lakeside Manor?

EPA lists Lakeside Manor as privately owned. The MO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 65 of the 92 active systems in Jefferson County (71%) are also privately owned.

Does Lakeside Manor have drinking water violations?

Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2024. The violations listed here began between January 1998 and October 2024. By type: 6 monitoring and reporting, 3 contaminant level above the legal limit, 2 public notice, recordkeeping or other and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 7 as archived and 5 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.
