How does Millcreek Inn compare with other water systems in Salt Lake County?
By EPA's size categories, Millcreek Inn is a very small system (500 people or fewer). Salt Lake County has 77 active public water systems. Its population served is well below the county average of 19,034 people per system, and accounts for less than 0.1% of the 1,465,589 people reported by systems filed under the county. Across Utah, the 1,133 active systems average 3,458 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Millcreek Inn is roughly in line with that figure.
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 under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 14 Utah systems (1.2%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Millcreek Inn?
EPA lists Millcreek Inn 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. 45 of the 77 active systems in Salt Lake County (58%) are also privately owned.
Does Millcreek Inn have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in December 2018. The violations listed here began between November 2008 and December 2018. By type: 9 monitoring and reporting, 1 public notice, recordkeeping or other, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Nitrate (4 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.
