Active sediment cap included in clean-up strategy at high-profile superfund site case study
Project: BROS Superfund Site
Location: LOgan TOWTtsNp. NJ
Products: Organoclay Reactive Core Mat
BACKGROUND: Historical operations at the BROS Super-fund Site included waste oil storage, processing and disposal. The waste oil operations in addition to a major earthen dike breach in the 1970's resulted in extensive damage to plant life and significantly impacted approximately three acres of the swamp. The wastes, which contain heavy metals, PCBs, and other organic compounds, have seeped into the soil and contaminate surface waters and ground water supplying private drinking wells. The Site was placed on the Superfund National Priorities List in 1983. Remediation of the BROS Superfund Site was complex and required management of many interconnected issues.
CHALLENGE: As part of the remediation strategy, the use of an Engineered Permeable Cap was included in the design utilizing CETCO's Organoclay81 filled Reactive Core Mat (RCM). RCM was installed to isolate residual COCsand to provide a stable base for restored plant community. Because of the potential for water flow, the cap also had to allow for water and gasses to pass through the barrier while still containing the contaminants.
SOLUTION: As part of the remediation strategy, use of an Engineered Cap was included in the design utilizing CETCO's Organoclay filled Reactive Core Mat. RCM was installed to isolate residual COCs and to provide a stable base for restored plant community.
RESULT: Installation of the Reactive Core Mat ran smoothly and on schedule, to the satisfaction of the Engineer, Contractor and EPA. While other remediation activities proceed on the site, the Reactive Core Mat proved to be an integral part of the total remediation strategy.
