Who’s Been Here? Using eDNA to Understand and Defend our Watershed  

Public Health Research Tualatin River Water Resources
There are many different ways the watershed talks to us, if you know how to listen. At Clean Water Services (CWS), we are always working to understand the needs of the Tualatin River Watershed. One way we learn from the environment is asking “who or what has been here?” Since we can’t knock on the door of a beaver dam or ring a trout’s doorbell, CWS is using a new technique to translate the language of the watershed.

Native Plants: Get to the Root of their Beauty and Benefits

At Clean Water Services, our favorite plants are native plants. Local birds, bees, and butterflies agree. Native plants are vitally important to protecting and supporting a healthy watershed. They are adapted to our climate, soils, and ecosystems.

Critical Infrastructure Meets the Natural Landscape 

When you kayak along the river or take a stroll through your neighborhood park, you may not realize the critical infrastructure just below the surface, hiding underground and carrying wastewater to a treatment facility or stormwater to a nearby waterway.

Clarified Vision: Planning and Building for Changing Communities and Climate 

The pipes, pump stations, stormwater systems, and treatment facilities that protect the health of all of us who live and work in Washington County are able to serve our growing communities because of decades of planning. The systems that will meet our needs 20 years from now will arrive thanks to planning being done today.

Testing the Waters: Inside the CWS Water Quality Lab

There's a lot of science involved in treating wastewater and managing stormwater in the uniquely challenging Tualatin River Watershed. A sizable portion of that science takes place in the Clean Water Services Water Quality Laboratory, where chemists perform over 100,000 water quality analyses a year.

Fireworks: Keep the Spectacle Out of Storm Drains 

We encourage people to have safe and joyous celebrations, but we also want to protect our slow and sensitive Tualatin River, which is a vital resource to our region. The Tualatin River provides drinking water, agricultural irrigation, and recreation. It’s also home to native wildlife like beavers, turtles, salmon, newts, egrets, and more. Keep these critters in mind when you clean up after using fireworks.
