Site background
Boeing has operated here since the 1960s, conducting research and development. They also manufacture components here. These activities led to contaminated soil and groundwater.
Boeing has an interim status permit at this site. Even though they did not get a final permit, Boeing must keep their permit active until they clean up the site.
In 2016, Ecology and Boeing signed an Agreed Order that required Boeing to conduct a Remedial Investigation. Their remedial investigation was approved in 2022. Ecology then required Boeing to do a focused Feasibility Study about the arsenic-contaminated groundwater on-site.
