System Upgrade May Impact PA Water Customers For 2 Months

LOWER MAKEFIELD TOWNSHIP, PA —PA Water customers may notice their drinking water may taste or smell a little funny starting Wednesday. And it might remain that way for two months.

But not to worry.

Pennsylvania American Water announced it is making a temporary change in its water treatment process from May 22-July 24 as a part of its normal distribution system maintenance.

PAWR is switching treatment to a form of chlorine known as “free chlorine,” which does not contain ammonia.

This stronger disinfectant is often used in conjunction with flushing water mains and fire hydrants.

Customers who have healthcare needs that require purified or filtered water should reach out to your healthcare provider with any questions.

During the temporary treatment change, customers may experience a more noticeable chlorine taste or odor in their water. This is due to the switch in chlorine types.

Temporary Treatment Process Changes

As part of our distribution system maintenance program, Pennsylvania American Water periodically changes its disinfection treatment process from a chloramine (combined) residual to free chlorine residual, the company said on its website.

During the time of this change, customers may notice an increase in the taste and smell of chlorine in the water. This is normal, poses no health risk, and will only be temporary while we complete this system maintenance.

The timeline for treatment changes varies throughout our systems in Pennsylvania, typically beginning in early spring and concluding in the fall. After the temporary change is complete in each system, we transition back to our regular disinfection process.
