Olympia's Water Quality ReportCity of Olympia Water Quality Report

City of Olympia staff work hard to ensure that Olympia's drinking water, which comes from a variety of sources, exceeds State and federal regulations.

Our annual Water Quality Report (WQR) includes Olympia's water quality test results and highlights the efforts and programs it takes to ensure we have great tasting, high quality water at a reasonable cost for generations to come.

Please note, the WQR is now online and will not be mailed to customers. If you would like a copy mailed to you, please contact Cheri Reimers at 360.709.2774 or creimers@ci.olympia.wa.us

Water pH

In April 2018, the pH of the City’s drinking water changed. The State Department of Health required the City to optimize the pH of our water because we’re considered a large water system (50,000 connections). In order to do this, we constructed the Meridian Corrosion Control facility that uses aeration towers (blown air, non-chemical) to raise the pH of the water coming from McAllister Wellfield. This reduces the chance of lead and copper leaching from household plumbing. The pH of the water is now between 7.0 – 7.6 and will remain at these levels permanently. Before the change, the City’s water pH was averaging between 6.5 – 6.8. 

Most City of Olympia water customers won’t notice a change to their water. Customers with fish tanks, home brewers or those with medical concerns (dialysis), or other activities where pH is a factor should take note. The City of Olympia continues to provide water that meets or exceeds State and Federal drinking water standards.
