Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 177 Missouri systems (6%) list purchased groundwater as their primary source.

Does Clark Pws have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2021. The violations listed here began between May 1985 and July 2021. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (9 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.
