Groundwater means the system draws its water from wells or springs fed by underground aquifers. 461 Arkansas systems (54%) list groundwater as their primary source.

Does Carthage Water and Sewer have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in April 2026. The violations listed here began between April 1996 and April 2026. By type: 5 monitoring and reporting, 3 public notice, recordkeeping or other, 2 contaminant level above the legal limit, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (10 of them). EPA lists 8 as archived, 2 as unaddressed and 2 as resolved. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
