How does Town of La Grange compare with other water systems in Goshen County?
By EPA's size categories, Town of La Grange is a very small system (500 people or fewer).

Across Wyoming, the 775 active systems average 838 people each. Nationally, the average active community water system reports serving 6,703 people, so Town of La Grange 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. Wyoming has 332 active community water systems, 43% 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 Town of La Grange?

Does Town of La Grange have drinking water violations?
Of the 12 most recent violations in EPA's records, 7 are health-based, and the most recent began in December 2011. The violations listed here began between September 1991 and December 2011. By type: 7 contaminant level above the legal limit and 5 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (12 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.
