Puget Sound’s blue waters are better because of the crimson and gray

Puget Sound is one of the state’s natural jewels. Whether sublimely calm and blue on a summer day or tempestuous and frothy during a winter gale, Puget Sound and its beautiful, iconic landscape draws you in and makes you want to stay.

The inland waterway has always been a place where humans like to gather. Home to over 50 named tribes, the Sound and its many rivers and tributaries supplied (and supplies) food and sustenance to the Salish whose ancient villages and long houses dominated the shoreline.

WSU research tucked inside traveling Capitol Christmas Tree

Tucked within the massive Capitol Christmas Tree headed for Washington, D.C. are three tiny sensors most people will never see. They will collect information on how well the tree holds moisture during its 25-day journey from Washington state.

Researcher Katie McKeever placed the data devices deep inside the canopy of the 88-foot-tall Engelmann spruce last weekend as it was loaded onto a flatbed trailer on the Colville National Forest in Pend Oreille County.

Creating Cleaner Water Vital to WSU Puyallup Researchers

Finding a solution to toxic highway runoff is critical to a group of Washington State University researchers and the environment. Using a method known as “soil bioretention” scientists at WSU Puyallup Research and Extension Center are testing collected runoff to measure the effects on fish and other aquatic life.

The Washington Stormwater Center Wins National Video Award for Treating Runoff

WSU Puyallup’s Lisa Rozmyn Project Producer

The Washington Stormwater Center (WSC) has received a prestigious national award for a video on a new way to treat runoff.

The Water Environment Federation awarded the top honor to the WSC in the Innovative Solution category for a low-cost treatment option for businesses managing heavy metals in their stormwater runoff.

“Businesses need stormwater treatment devices that work,” said Lisa Rozmyn, Business Resource Program Manager for the Washington Stormwater Center. “We hope this video will show people that effective stormwater treatment doesn’t have to be complicated and expensive, and that they can build it themselves for very little money.”

The video, produced in conjunction with the Port of Vancouver’s Matt Graves and Mary Mattix who invented the new bioretention method, details the process for removing zinc from stormwater runoff. Zinc, found in galvanized metal roofs, downspouts, tires, chain link fences and motor oil, contains toxins harmful to aquatic life and the environment.

The WSC, a collaboration between Washington State University and the University of Washington, provides tools for stormwater management by supporting municipalities, stormwater permittees, and businesses in their efforts to control stormwater and protect water quality.
