How does Cloverdale Montessori School compare with other water systems in Ada County?
By EPA's size categories, Cloverdale Montessori School 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 non-transient non-community water system reports serving 430 people, so Cloverdale Montessori School 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. Idaho has 242 active non-transient non-community water systems, 12% of the state's 1,961 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,861 Idaho systems (95%) list groundwater as their primary source.
Who owns and regulates Cloverdale Montessori School?
EPA lists Cloverdale Montessori School 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 Cloverdale Montessori School have drinking water violations?
EPA's records list 11 violations for this system; 5 are health-based, and the most recent began in July 2017. The violations listed here began between March 1991 and July 2017. By type: 5 monitoring and reporting, 5 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 9 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.
