(KNZA)--The Kansas Department of Health and Environment (KDHE) has rescinded a boil water advisory for the City of Effingham public water supply system located in Atchison County.

The advisory was issued Monday because of a line break resulting in a loss of pressure in the system. KDHE says failure to maintain adequate pressure may result in a loss of chlorine residuals and bacterial contamination.

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