Does Lpwd South have drinking water violations?
EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in July 2010. The violations listed here began between July 1994 and July 2010.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (2 of them). EPA lists 3 as archived and 2 as resolved.
