Check out the 2019 Drinking Water Quality Report!

The 2019 Drinking Water Quality Report outlines how we are continuing to deliver clean and safe drinking water to nearly a million customers.

Portland’s drinking water comes from two high-quality sources—the Bull Run Watershed and Columbia South Shore Well Field.

What’s in the Report?

The report summarizes water quality results for 2018 and includes information about how we monitor, treat, and distribute your drinking water. The report also provides information on Portland’s drinking water system and how customers can reduce their exposure to lead in drinking water, including by requesting a free-lead-in-water test kit.

Making Excellent Water Better

The report also highlights two major treatment improvements Portland is undertaking. These improvements will provide increased public health protection against lead in household plumbing and Cryptosporidium, an organism that can potentially cause illness. These improvements will also result in more consistent water quality and prepare the water system for future regulations.

How to Access the Report

The Portland Water Bureau is mailing a postcard this week to inform every customer about the availability of this report online. Customers can request a paper copy, either online or by phone.
