How does Lacon Water Co Op compare with other water systems in Kootenai County?
By EPA's size categories, Lacon Water Co Op is a very small system (500 people or fewer). Kootenai County has 182 active public water systems. Its population served is well below the county average of 983 people per system, and accounts for less than 0.1% of the 178,930 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 Lacon Water Co Op 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 Lacon Water Co Op?
EPA lists Lacon Water Co Op as owned by a local government. 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. 30 of the 182 active systems in Kootenai County (16%) are also owned by a local government.
Does Lacon Water Co Op have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2018. The violations listed here began between October 2005 and January 2018. By type: 5 monitoring and reporting, 5 monitoring, 1 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (6 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.
