The Pennsylvania Department of Environmental Protection will install three monitoring wells throughout Horsham to assess how widespread wellwater contamination is in the area.
Since the monitoring wells will be installed on township property, Horsham Township Council was asked to weigh in on the plan, and it gave its unanimous approval at Monday's meeting.
The wells will be looking for high levels of perchloroethylene, or PCE, which has been found in private wells in the township. Possible locations for the wells include and Balmoral Way.
Pending the results of the analysis, DEP could install another three monitoring wells, but those will likely be placed on private property.
So far, DEP has tested 33 private wells in the township and found 11 of them to have high levels of PCE. DEP recommended that residents of those homes use bottled water.
PCE is typically associated with chemicals released from dry cleaning and metal cleaning.
Township manager Bill Walker said DEP is expected to formulate a plan this year to address the contamination.
"We're happy with the progress they're making," he said. "They're working to find out where this came from and to see if this is concentrated in a small area. We expect a decision by the end of the year. This isn't something that will drag on for years and years."
