Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 142 South Dakota systems (20%) list purchased surface water as their primary source.

Does Pickstown have drinking water violations?
EPA's records list 8 violations for this system; 2 are health-based, and the most recent began in June 2014. The violations listed here began between January 1993 and June 2014. By type: 5 monitoring and reporting, 2 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (2 of them). EPA lists 5 as resolved and 3 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.
