Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 237 Arkansas systems (28%) list purchased surface water as their primary source.
Who owns and regulates Buena Vista-Ogemaw Water Association?
EPA lists Buena Vista-Ogemaw Water Association as privately owned.

Does Buena Vista-Ogemaw Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in December 2025. The violations listed here began between July 2015 and December 2025. By type: 6 monitoring, 3 contaminant level above the legal limit, 2 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 9 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. 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.
