Jesse Freeman, PE, LSP

Mr. Freeman is a Massachusetts Licensed Site Professional (LSP); a registered Professional Engineer (PE) in Massachusetts, Rhode Island, and New Hampshire; and maintains the National Radon Proficiency Program (NRPP) radon measurement, mitigation, and radon-resistant new construction certification. Mr. Freeman’s expertise includes environmental engineering; site investigation; remediation; environmental permitting; and compliance for stormwater, wastewater, and air emissions. Mr. Freeman has worked on a wide variety of projects and has successfully conducted remediation for releases of chlorinated solvents, metals, petroleum, LNAPL/DNAPL, VOCs, SVOCs, PAHs, PCBs, reactive and hazardous waste, and sub-slab and indoor air contamination. Projects for which Mr. Freeman has provided environmental services have ranged from small residential releases, gasoline stations, and dry cleaners, to large industrial operations, off-shore oil spills, and multi-acre brownfield projects undergoing development.

• Project Manager and Certified Radon Measurement Professional and Radon Mitigation Specialist for the Sampling and Mitigation of Radon within a School Building. Conducted a radon sampling event in accordance with ANSI/AARST MA-MFLB-2023 Protocol for Conducting Measurements of Radon and Radon Decay Products in Multifamily, School, Commercial and Mixed-Use Buildings. Radon sampling indicated elevated radon concentrations within an office on the lower floor of the school. The school was constructed directly on bedrock, and a bedrock outcrop was present within the office and the neighboring storage space (which was behind a block and concrete wall). This created a unique challenge, where the route of entry could not be mitigated using standard sub-slab depressurization system. To address the issue, Roux constructed an “airtight” PVC box around the outcrop in the office and connected PVC piping to the box to work as the radon mitigation system.
• Brownfields Redevelopment Cambridge, Somerville, and Boston, Massachusetts. Project manager and LSP of record for the remediation of a 37-acre parcel as part of redevelopment of the property from industrial activities to mixed-use residential, commercial, life sciences, commercial space, and green space. Contamination at the project included PCB at concentrations regulated under the Toxic Substances Control Act, asbestos-containing materials, heavy metals, VOCs, SVOCs, sulfide reactive soil, characteristic hazardous waste, LNAPL (petroleum), and DNAPL (MGP). Oversaw the submittal of Permanent Solutions as required by the Massachusetts Contingency Plan on parcels closed with and without Activity and Use Limitations (AULs). Successfully completed closure of a parcel with LNALP present at measurable quantities using MassDEP-approved LNALP transmissivity calculations.
• Former Industrial Plot Development, Wayland, Massachusetts. Project Manager and principal decision maker for the redevelopment of a parcel of land formerly occupied by a defense contractor. Releases of PCBs, CVOCs, coal and coal ash, and metals to soil and groundwater were identified. Coordinated the excavation, cleaning, and removal of multiple underground storage tanks (USTs) and subsurface structures (former building rooms that had been abandoned in place). Hydraulic lifts were encountered during development of the property. Designed and oversaw the installation of sub-slab vapor mitigation systems to mitigate petroleum and chlorinated solvent vapors from entering buildings being constructed at the development site.
• Petroleum Service Station, Connecticut. Designed a remediation system to address release of petroleum hydrocarbons to the subsurface. The release occurred from a gasoline station located at the top of a hill. In addition, a release from an adjacent dry cleaner was co-mingled with the petroleum release. Petroleum hydrocarbons traveled down to a depth of approximately 25 feet below grade at the service station, to 3-5 feet below ground surface at the head of the plume. Remediation was initiated at the property by the former station owner who used in situ chemical oxidation (ISCO) to remediate the release. Recognizing that ISCO was not the appropriate remedy, as the majority of the oxidant was consumed by the surrounding soil, designed a soil vapor extraction (SVE) and air sparge (AS) system to complete remediation. Within 30 minutes of activation, the soil vapor extraction system had collected the remaining LNAPL.
• CERCLA Superfund Landfill, New Hampshire. Responsible for coordinating environmental investigations to evaluate potential remedial options for multiple releases coming from a former municipal landfill. Releases included VOCs, metals, methane, landfill leachate, methyl mercaptan, and corrosive groundwater. Conducted a field gas chromatography (GC) testing program to identify the extent of a VOC plume below the northern portion of the landfill. The GC successfully identified the extent of the release by analyzing samples of groundwater on-site. The release was identified in both the northern portion of the landfill, and in areas along the eastern portion of the landfill which were previously not identified. Field GC results were generally within 10% of those samples submitted for analysis at an independent laboratory. A second release was identified to extend from the landfill to a nearby river. Coordinated and collected samples of river sediment to be submitted for site-specific toxicological analysis. Toxicological analysis was conducted at a laboratory using benthic organisms, which concluded that the release was not affecting the river organisms.
• CERCLA Superfund Landfill, Massachusetts. Primary field technician evaluating a release from a former drum disposal project in Massachusetts. Duties included overseeing the installation of groundwater monitoring wells, advancement of soil borings, installation of a sheet pile wall containment cell, and the implementation of the remedial alternative ISCO using potassium permanganate within the sheet pile walls. DNAPL (CVOCs) was present in several wells. Concentrations of CVOCs identified during the installation of the groundwater monitoring wells were high enough that Level B personal protective equipment was required during the installation of groundwater monitoring wells. The ISCO mitigation was successful in reducing the overall contaminant mass; however, layers of silt and clay present in the subsurface continued to act as a source of contamination. Using knowledge of the Site, the limitations, and requirements from the USEPA during the initial work, vetted remedial contractors to continue and complete the remediation at the property.
