The US Army Corps of Engineers (USACE) is addressing the Formerly Utilized Sites Remedial Action Program (FUSRAP) Middlesex Sampling Plant Site (MSP) in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The MSP has been an active FUSRAP site since the early 1980's and was listed on the National Priority List (NPL) in 1999. Two challenges that the project team are currently addressing are Ground Water (GW) movement through fractured bedrock and Vicinity Properties (VP) assessments. USACE and the US Environmental Protection Agency (USEPA) signed a Record of Decision (ROD) for soils remedial action in 2005 and USACE completed the soils remediation at MSP in 2008, however, VPs were not a part of the soils ROD. Additionally, the State of New Jersey recently identified a potential contaminated VP of the site. VPs are any property in the vicinity of a CERCLA 'facility.' The contaminated VPs of the MSP were addressed prior to the adoption of the CERCLA process to address FUSRAP sites. Since the 1980's many changes to potential Applicable or Relevant and Appropriate Requirements have occurred. As such USACE has begun reassessing the previously addressed VPs for inclusion under the soils ROD as part of the CERCLA process. USACE does expect to have to revisit and potentially remediate up to 12 VPs. This paper will discuss the approach, some challenges, and lessons learned in adequately addressing VPs both from a field work and a post ROD regulatory perspective. USACE is currently in the Feasibility Study phase of the CERCLA process for GW. The project team has encountered and overcome significant challenges with regard to contaminant plume bounding and groundwater movement through the secondary porosity of dipping bedding plane partings and fractured bedrock of the Passaic Aquifer beneath the site. This paper will discuss the challenges, the approaches used, and lessons learned while delineating these contaminants. This paper's discussions are useful for anyone addressing an environmental site with soils contamination on VPs or with delineating contaminants in fractured bedrock. (authors)
