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. South Dakota has 173 active transient non-community water systems, 25% of the state's 699 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 431 South Dakota systems (62%) list groundwater as their primary source.
Who owns and regulates Beaver Lake Campground?
EPA lists Beaver Lake Campground as privately owned. The SD state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 27 of the 49 active systems in Custer County (55%) are also privately owned.
Does Beaver Lake Campground have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in April 2025. The violations listed here began between June 2001 and April 2025. By type: 4 contaminant level above the legal limit, 3 public notice, recordkeeping or other, 2 monitoring and reporting, 1 monitoring, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (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.
