How does Danube compare with other water systems in Renville County?
By EPA's size categories, Danube is a very small system (500 people or fewer). Renville County has 28 active public water systems. Its population served is about 12% above the county average of 398 people per system, and accounts for 4% of the 11,133 people reported by systems filed under the county. Across Minnesota, the 6,465 active systems average 820 people each. Nationally, the average active community water system reports serving 6,703 people, so Danube 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. Minnesota has 987 active community water systems, 15% of the state's 6,465 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,261 Minnesota systems (97%) list groundwater as their primary source.
Who owns and regulates Danube?
EPA lists Danube as owned by a local government. The MN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 14 of the 28 active systems in Renville County (50%) are also owned by a local government.
Does Danube have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in April 2020. The violations listed here began between October 1993 and April 2020. By type: 4 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Combined Radium (-226 and -228) (3 of them). EPA lists 4 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.
