This winter and spring I have noticed a stronger chlorine taste to my water, is Portland Water District adding more chlorine?

During the winter and spring months PWD actually adds less chloramine (chlorine compound) to the water, but because of the colder water temperature chlorine lasts longer (doesn’t dissipate as quickly) as the water travels through the water distribution system. Therefore, depending where you live, you may experience slightly more chlorine taste in the winter/spring than in the summer/fall.

In the drinking water distribution system, adding chlorine and maintaining a residual amount throughout the water distribution system provides protection against the risk of microbial contamination after treatment.
