Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 62 New Mexico systems (5.3%) list purchased groundwater as their primary source.

Does Riveras Mdwua have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in October 2023. The violations listed here began between July 1991 and October 2023. By type: 4 monitoring and reporting, 2 public notice, recordkeeping or other, 1 monitoring, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 8 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.
