PROJECT PROFILE
Citadel EHS implemented and
manages the remediation of a high-priority dry-cleaning site in Marin County, under the oversight of the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB).
The site, which is among SFBRWQCB’s highest-priority cases, was impacted by chlorinated volatile organic compounds (VOCs) contamination in soil, soil vapor, and groundwater
from historical dry-cleaning operations.
The remediation implemented by Citadel addressed impacted soil, soil vapor, and groundwater with VOC impacts that extended approximately half a mile off-site.
The project included significant public stakeholder involvement and litigation from nearby property owners, which, with Citadel’s support, resulted in a 12-0 jury decision in favor of our client.

Key remedial actions undertaken include:
- Soil Excavation: Excavation and removal of PCE-impacted soil from the former dry-cleaning area.
- Soil Vapor Extraction: Localized SVE to treat residual soil vapor
- In-Situ Chemical Reduction (ISCR): Two rounds of ISCR injections (approximately 65 injection borings per event) of treatment amendments in groundwater to accelerate the breakdown of PCE and its breakdown products.
- On and off-Site Sewer Lateral Removal: Removal of an abandoned sewer lateral to eliminate a preferential pathway for contaminant migration.
- Ongoing monitoring of groundwater and soil vapor to assess natural degradation trends
