Water Quality Report

May contain: body part, hand, person, washing, and sink

Welcome to the OLWS 2022 Water Quality Report. The drinking water information presented in the report is based on monitoring results from the 2021 calendar year. 

The Environmental Protection Agency (EPA) and Oregon Health Authority laws require the District to provide our consumers with a detailed report showing you what is in the water you drink.  OLWS continually strives to adopt new and better methods for delivering the best quality drinking water standards. The testing results in the District continue to meet and exceed state and federal guidelines for public health. 

Request a paper copy of the report at or call (503) 654-7765. For more information about this report, or for any questions relating to your drinking water, please call Marty Guenther, Pollution Prevention Specialist, at (503) 753-9689.
