About the Project

This project will cleanup soil and groundwater contamination from former dry cleaners located on the site west of City Hall on the east side of Bothell Way NE between SR 522 and NE 185th St known as the Ultra site. The project involves excavating to remove contaminated soil at the original site of the dry cleaners and injecting a series of treatment barriers directly into the groundwater to break down contaminants within the plume, which will prepare the site for future use.
