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. Wyoming has 91 active non-transient non-community water systems, 12% of the state's 775 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 585 Wyoming systems (75%) list groundwater as their primary source.
Who owns and regulates Georgia-Pacific Gypsum LLC?
EPA lists Georgia-Pacific Gypsum LLC as privately owned. The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 9 of the 28 active systems in Big Horn County (32%) are also privately owned.
Does Georgia-Pacific Gypsum LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, 12 are health-based, and the most recent began in July 2015. The violations listed here began between July 2011 and July 2015. By type: 12 contaminant level above the legal limit. The contaminant or rule involved most often is Selenium (6 of them). EPA lists 9 as archived and 3 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.
