What does “transient non-community water system” mean?
A transient non-community water system serves places where people do not stay long, such as gas stations and campgrounds, and regularly serves at least 25 people a day for at least 60 days a year. Utah has 509 active transient non-community water systems, 45% of the state's 1,133 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 898 Utah systems (79%) list groundwater as their primary source.
Who owns and regulates Hidden Lake Association?
EPA lists Hidden Lake Association as privately owned. The UT state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 53 of the 79 active systems in Summit County (67%) are also privately owned.
Does Hidden Lake Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in January 2023. The violations listed here began between January 2011 and January 2023. By type: 7 monitoring and reporting, 2 required treatment not met, 1 public notice, recordkeeping or other, 1 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 11 as resolved and 1 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.
