How does Parma Research and Extension Center compare with other water systems in Canyon County?
By EPA's size categories, Parma Research and Extension Center is a very small system (500 people or fewer). Canyon County has 140 active public water systems. Its population served is well below the county average of 1,527 people per system, and accounts for less than 0.1% of the 213,824 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 Parma Research and Extension Center 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 Parma Research and Extension Center?
EPA lists Parma Research and Extension Center 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. 123 of the 140 active systems in Canyon County (88%) are also privately owned.
Does Parma Research and Extension Center have drinking water violations?
EPA's records list 8 violations for this system; 4 are health-based, and the most recent began in October 2011. The violations listed here began between July 1996 and October 2011. By type: 4 contaminant level above the legal limit, 3 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 4 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.
