Approximately 170 creosote-saturated piling will be removed from Vashon and Maury islands starting Monday, the Washington State Department of Natural Resources announced in a statement Friday morning.
The two-week cleanup project will cost an estimated $161,555. The DNR contracted the Quigg Brothers, an Aberdeen company, for the project.
Creosote, used for more than a century, is a combination of more than 300 chemicals used to prevent decay.
“These chemicals are harmful to marine life that depend on a healthy Puget Sound for their habitat,” Megan Duffy, Deputy Supervisor of Aquatics and Geology for DNR, said in a prepared statement. “Though creosote was once widely used, we are now seeing the harmful effects these chemicals can have on our waterways and are working to eliminate that harm.”
Last year, DNR removed 1,769 creosote-treated piles and 1,235 tons of creosote debris from Puget Sound.
