Erie Water Works has announced plans to boost minimum chlorine levels in the region's drinking water due to new Pennsylvania state regulations. The utility, which serves northwest Pennsylvania, announced the increase in response to a new Pennsylvania Department of Environmental Protection mandate that public water system reach a minimum chlorine level of .20 ppm, an increase from the previous minimum of .01 ppm. The utility has cautioned customers that the change may impact taste and smell of drinking water.

With roughly 53,000 direct residential customers in Erie, Lawrence Park Township, Wesleyville Millcreek Township, Harborcreek Township, McKean Township and Summit Township, Erie Water Works’ distribution reach is wide. Consequently, treated water will leave the water Wasielewski Water Treatment Plant at 1.75 ppm to ensure it meets minimum standards throughout the system, Erie Water Works CEO Paul Vojtek told local news source Go Erie.

“When the water’s coming in, obviously there’s no chlorine in it,” Vojtek said. “But as it’s going out into the system, the chlorine dissipates the further you go out south, east and west from our central locations.”

Erie Water Works has gradually been increasing its chlorine levels over the past few months, in anticipation of the new regulations taking effect. Customers may notice a difference in taste and odor of their drinking water with increase in chlorine concentration.
