(KNZA)--The Kansas Department of Health and Environment has rescinded a boil water advisory for the Jefferson County community of Ozawkie.

The advisory was issued Monday because the system was unable to maintain required chlorine residual levels. Failure to maintain adequate chlorine residuals may lead to bacterial contamination.

KDHE says laboratory testing samples collected from the City of Ozawkie indicate no evidence of bacteriological contamination and all other conditions that placed the system at risk of contamination are deemed to be resolved.
