(Matrix) is pleased to submit this proposal for professional environmental services. This proposal includes costs for Matrix to provide oversight of groundwater sampling activities being performed by the United States Environmental Protection Agency (EPA) at several Township properties, including; 18 Central Avenue (Former Selecto Flash)(Block 9; Lot 36), 4-10 Central Avenue (Former Biddelman)(Block 9, Lot 32), and 55 Lakeside Avenue (Former Barton Press)(Block 155, Lots 15 and 17). The groundwater sampling activities are associated with on-going investigations related to the Orange Valley Regional Groundwater Contamination Superfund Site and will be conducted by HDR, Inc. on behalf of the United States EPA. SCOPE OF SERVICES The scope of services and associated fee is summarized in detail below: Task 1: Oversight Groundwater Sampling Event Completed by EPA Matrix will complete third party oversight of HDR, Inc. on behalf of the EPA conducting groundwater sampling at the above referenced properties. The scope of work includes the collection of groundwater samples from select monitoring wells throughout the Township of West Orange and the City of Orange to monitor the impacted groundwater plume associated with the Orange Valley Regional Groundwater Contamination Superfund Site. The monitoring wells located at each of the above referenced Township properties that are included in the proposed sampling schedule are identified below: - Barton Press Site: Monitoring wells MW-2D, MW-3D, MW-4D, and MW-6D Selecto Flash Site: Monitoring wells MW-1DS, MW-4D, and MW-5D Biddelman Site: Monitoring wells MW-1D, MW-2D, and MW-12D Each of the above referenced monitoring

ng wells MW-2D, MW-3D, MW-4D, and MW-6D Selecto Flash Site: Monitoring wells MW-1DS, MW-4D, and MW-5D Biddelman Site: Monitoring wells MW-1D, MW-2D, and MW-12D Each of the above referenced monitoring wells will be sampled for chlorinated volatile organic compounds (CVOCs), metals, and per- and polyfluoroalkyl substances (PFAS). Please note that the NJDEP requires all EPA Superfund Sites to be sampled for PFAS. Matrix has budgeted three (3) days of oversight for each sampling event for the above scope of work and will only invoice actual time spent. No sampling will be completed by Matrix. Based on the executed access agreements between the EPA and the Township, potentially two (2) additional rounds of groundwater sampling were required at the above referenced properties. The first event was completed in August 2024 with Matrix oversight.
