Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 71 Arizona systems (4%) list purchased groundwater as their primary source.

Does Seba Dalkai Boarding School Bia have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in April 2025. The violations listed here began between July 2023 and April 2025. By type: 4 contaminant level above the legal limit, 3 public notice, recordkeeping or other, 2 reporting, 2 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (4 of them). EPA lists 7 as resolved, 4 as unaddressed 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
