Does City of Alamo have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in December 2023. The violations listed here began between July 2008 and December 2023. By type: 11 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Lead and Copper Rule (5 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.
