2. 2. Doll's Place Restaurant Located at 101 Paterson Street New Brunswick, NJ Established in 1933 by William Doll Heffernan Original location was 27 French Street, New Brunswick (on the other side of the train tracks) Robert Wood Johnson Hospital bought the property on French Street and Doll's Place moved to the Paterson Street in 2005.
3. 3. Site Use History Formerly New Swift Cleaners Location is in downtown New Brunswick in a congested area with little room to work
4. 4. Past Contamination May 2001 After the 550 Gallon No. 2 Storage tank that was on the property was removed, the contamination left over was reported to NJDEP (Incident No:01-05-01-1535-46) Tank may have contained dry cleaning solvents December 2001 Groundwater samples were collected from the area of concern where the UST was located Analytical results from monitoring well (MW-1) revealed elevated levels of chlorinated volatile organic compounds (CVOCs) in ground water Tetrachloroethylene (PCE) - 48,000 ppb Trichloroethylene (TCE) at 8,100 ppb
5. 5. Remedial Action: New Swift Cleaners July 2002 DEP requested sampling action to be taken on the property that at the time was a dry cleaning business. After non-response and non-compliance from the responsible party, NJDEPs Bureau of Environmental Measurements & Site Assessment (EMS) referred this case to the Publicly Funded Remediation Element for evaluation due to its potential to be an Immediate Environmental Concern.
6. 6. Areas of Concern & Sampling: Doll's Place August 2012 DEP requested groundwater samples to confirm the concentration of PCE, TCE and the possible PCE breakdown products. Groundwater samples showed: PCE: 35,000 ppb (parts per billion) TCE: 10,000 ppb September 2012 Indoor air and sub-slab soil gas sampling in September 2012 showed indoor levels of PCE as high as 3,300 ug/m3 in the basement and 280 ug/m3 in the restaurant. Case was assigned to Bureau of Site Management in November 2012 in order to install a sub-slab depressurization system (SSDS).
7. 7. Remedial Action: Doll's Place November December 2012 Site inspection with the Subsurface Remediation Services Contract Term A81464 Contractor, Envirotech Consultants, LLC (Envirotech) A cost estimate for the project was made February March 2013 Initially decided to alleviate the generation of a basement negative pressure and to properly contain the basement exhaust fan exhaust as well as to generally seal the basement walls and floor.
8. 8. Details on Remediation February March 2013 1 SVE point was installed to a depth of 18 inches below the bottom of (5 inch thick) slab. Ten monitoring points were installed throughout the ground floor of the building. Testing indicated moderate at best soil gas movement with - 2 pascals vacuum measured between 17-22 feet from the SVE point (with 78 inches of water applied vacuum). It was also observed that the ducting from the basement exhaust fan was leaking into the office area close to where the highest level of ground floor IA PCE was observed. Laboratory Results: Sub-slab PCE concentration was 380 ug/mt Basement IA was 6,800 ug/m (18 times higher) Office area had 280 ug/m PCE level decreases as one gets further from the office

17. 17. Remediation: Dolls Place March 2013: Basement walls and floors were sealed and the existing attic exhaust fan was replaced with a Fantech in line fan hard piped (6 inch) to the outside and discharging above the roof line.
18. 18. March 2013: Shown: Sealing of the basement walls and floors. Walls were painted with 2 coats of water proofing paint. Outside air will enter through that portion of the existing fan discharge not occupied by pipe. Remediation: Dolls Place
19. 19. Remediation: Dolls Place March 2013: Shown: Basement Floor Sampling Point Floors were sealed with a thin coating to 1 inch thick of self-leveling compound (a proprietary blend of copolymers, Portland cement, sand and inorganic chemicals) Parts of the floor were soil and were patched with grout prior to flooring application.

22. 22. One of the first pictures of the completed depressurization system from the back of the establishment.
23. 23. Bollards were installed outside to protect the fan discharge pipe.
24. 24. Indoor air testing will be performed during the cooling and heating seasons because worst case site conditions appear when the exhaust fan is on-in warmer weather during the cooling season. (This is planned for June and December 2013.) Indoor Air Testing
