September 2015 Update
The Interim Remedial Measure (IRM) work is set to begin, which will address the contamination related to the site at Kent Ave & 12th Street.
A public meeting will be held on September 29, 2015 to discuss the cleanup activities and what the community can expect throughout the duration of the work. The meeting will be held at 6:30pm at the Bushwick Inlet Park Headquarters at Kent Ave. and N. 9th St. in Brooklyn.
The goal of the cleanup is to achieve levels that protect public health and the environment. The cleanup action for the site includes:
- Excavation and off-site disposal of two gas holder foundations and associated coal tar-contaminated soil to an approximate depth of 25 feet;
- In-situ stabilization/solidification (ISS) of one of the gas holder foundations and its contents;
- Installation of recovery wells immediately outside the 50 Kent Ave. parcel in the street rights of way to collect non-aqueous phase liquid (NAPL) which lies beyond the boundaries of the excavation; and
- Soil on the remainder of the 50 Kent Ave parcel will be excavated to the water table, approximately 5 feet below ground surface, and disposed off-site. The site will then be returned to approximately its existing grade. A soil cover, consisting of a minimum of two feet of soil meeting Restricted Residential Soil Cleanup Objectives, which also allows for active recreational use, will be placed across the entire site.
On-going and future work at the Site includes:
- Ongoing biweekly non-aqueous Phase Liquid (NAPL) gauging and recovery at wells on North 11th and North 12th Streets; and
- Installation of piezometer in the sidewalk on the west side of Kent Avenue, between North 11th and North 12th Streets scheduled for Friday September 25, 2015.
