Water Quality

Safe, reliable drinking water is a basic necessity of life and a top priority for the City of Tualatin. The City delivers water to more than 27,000 people every day and we believe it is important for our customers to understand where their water comes from, how safe it is, and what actions we take to ensure its continuing high quality.

Every year the City of Tualatin provides this information to our customers in our annual Water Quality Report. The report includes information about our water sources, the previous year's testing results, and water monitoring programs. This report contains information from both the City of Tualatin and the City of Portland, where we purchase our water from. 

If you would like a free printed copy of the report please send us an email or call 503-691-3091 and we will send one to you! 

For complete results of all of our water sampling visit the Oregon Health Authority's (OHA) Drinking Water Data Online website. 

If you have any questions or would like additional information, contact Terrance Leahy, the Water Division Manager at 503-691-3095 or tleahy@tualatin.gov.

Please note: All of the City's water quality reports can be found below. As of 2019, the City will begin dating the reports based on the year they are produced, not the year from which the data was collected. We hope this provides clarity when looking for the most current Water Quality Report. This is why you won't find a 2018 Water Quality Report below.
