Bothell Landing
When the city started to develop Rotunda Park, they found five abandoned underground storage tanks from a previous gas station. This site was contaminated with petroleum from the underground tanks and solvents from the nearby Ultra Custom Care Cleaners site. Contaminated soil was excavated and capped under the roadways. Environmental covenants restrict access to the soil and groundwater.

Bothell Paint & Decorating
This site used to have fuel, auto repair, paint, and sandblasting businesses. Soil was contaminated with petroleum from an underground storage tank. Sandblasting left metals in the shallow soil.
Contaminated soil was removed, except for a portion under SR 522. Institutional controls will be put on the property to keep people from disturbing the contamination.

Bothell Service Center Simon & Son
Parts of the Soil Vapor Extraction system used to remove contamination in 2019.
Bothell Former Hertz
The former Hertz site before and during cleanup.
This was a rental car dealership. The buildings were demolised to make way for a new section of State Route 522. Leaking underground storage tanks contaminated the soil with petroleum, which has been cleaned up.
The groundwater was contaminated with petroleum and also vinyl chloride and solvents. A lot of that contamination seems to be coming from the Bothell Service Center Simon & Son site next door, which is being cleaned up. Groundwater here will be monitored to see if cleaning up the neighboring site and natural processes solve the problem.
