Project Snapshot: ISS/ISCO at Former Dry Cleaners

The site of a former dry cleaning shop in Seattle was found to be contaminated with chlorinated volatile organic compounds (CVOCs), and Cascade was brought in to perform in situ chemical oxidation (ISCO) and in situ stabilization (ISS) to address them.

The site was very small and located in a mixed residential and small business neighborhood. Read the project highlight to learn how crews performed the work while minimizing disruption to the surrounding area.
