WICHITA, Kan. (AP) — Wichita public works officials say a dozen homes in west Wichita where groundwater contamination has been found will be connected to the city’s water supply.

KAKE-TV reports the 12 homes are close enough to existing water mains to be connected immediately to city lines. A private plumber will have to install service lines into the homes. A state health department program will pay for the connections.

City officials have found about 50 homes with high concentrations of a toxic dry-cleaning solvent in their private wells. Those homes have been using bottled water since the contamination was found in March
