Case Study #2 - Plastics Facility, Newark Case Study #3- Metal Barrel and Drum Cleaning and Reconditioning Facility Case Study # 4 - Research & Development Facility The Problem: Several thousand gallons of research grade gasoline migrated below the active R & D facility. Remedial investigation (by Hudson) indicated at least 80% of the phase-separated plume existed below the facility. Strict quality control of indoor air quality and no disruption of operations were critical the factors that dictated an alternative approach to remedial investigation and remedial design.

Case Study # 5 - Tool Manufacturing Facility The Problem: A thorough preliminary assessment (PA) and site investigation identified seven (7) areas of concern (AOC). Based on the PA, four of the AOCs would require remediation prior to any sale AOC-1 and AOC-2: two previously unknown Underground Storage Tanks (USTs) were identified, one in the building under the floor slab and the other partially under the foundation to a new addition. AOC-3: A drum storage rack was staged over a catch basin thought to drain to the facility's floor drain system. In actuality, the catch basin was a former window well with a soil base. AOC-4: an outside dumpster was used to store metal shavings from tool production. The shavings were coated with cutting oil, which discharged onto the pavement and were released to the environment. The Solution: Recognizing the need for site cleanup as a prerequisite for the sale of the facility, Hudson was retained to develop and implement the voluntary cleanup program under an MOA. The goal was to conduct the cleanup in advance of the ISRA triggering action and allow the sale to proceed as scheduled.

The most significant AOC, a former wastewater lagoon, existed near a property boundary. Subsequently, chlorobenzene and other constituents were detected in groundwater, surficial soils and sediments. Impacted groundwater migrated off-site and Hudson assisted counsel for the client with acquisition of insurance coverage for environmental investigation and remediation costs. Client desires to investigate and clean up site without an aquifer Classification Exception Area (CEA) or Deed Notice (DN). The Solution: Hudson was retained to complete the site investigation in a phased approach under the MOA. Hudson was also retained to mitigate groundwater, soil and/or sediments contamination and to secure the No Further Action (NFA) letter from the NJDEP without the need for a CEA or a DN. Upon an initial groundwater and soils investigation, Hudson determined that lagoon sludge and vadose zone soils were likely contributing to groundwater contamination. Hudson recommended that soils be addressed first, followed by groundwater and sediments .
