How does West Meadows Estates compare with other water systems in Ada County?
By EPA's size categories, West Meadows Estates is a very small system (500 people or fewer). Ada County has 87 active public water systems. Its population served is well below the county average of 5,880 people per system, and accounts for less than 0.1% of the 511,514 people reported by systems filed under the county. Across Idaho, the 1,961 active systems average 899 people each. Nationally, the average active community water system reports serving 6,703 people, so West Meadows Estates 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. Idaho has 765 active community water systems, 39% of the state's 1,961 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 15 Idaho systems (0.8%) list purchased surface water as their primary source.
Who owns and regulates West Meadows Estates?
EPA lists West Meadows Estates as privately owned. The ID state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 71 of the 87 active systems in Ada County (82%) are also privately owned.
Does West Meadows Estates have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2019. The violations listed here began between April 2000 and January 2019. By type: 8 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 8 as archived and 4 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.
