An authority in Charleroi was investigating a third water line rupture on a pipeline that led Tuesday to a boil-water advisory in the Mon Valley.
Monessen Councilman David Feehan said the line broke again on a major transmission line on a hill in Rostraver Township where a landslide along Route 906 was also under investigation.
The section of roadway is in Rostraver Township.
Valerie Petersen, spokeswoman for the state Department of Transportation, said PennDOT crews were monitoring the landslide, which was caused by line rupture.
Route 906 did not close due to the landslide, which required plow trucks to move mud from the roadway.
The boil-water advisory remained in place until further notice in Monessen, North Charleroi, Charleroi and Speers, Pappasergi said.
The water supply will be tested again Thursday to confirm whether it tests negative for the presence of disease-causing organisms.
