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 Valley Springs?

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. 10 of the 15 active systems in Minnehaha County (67%) are also owned by a local government.
Does Valley Springs have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in November 2020. The violations listed here began between July 1976 and November 2020. By type: 7 monitoring and reporting, 3 required treatment not met and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 7 as resolved and 5 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.
