Mr. Swan’s skill set combines critical thinking and comprehensive expertise with New Jersey and Pennsylvania environmental regulatory programs with exceptional computational skills to develop conceptual site models (CSMs), 3-dimensional visualizations, and numerical groundwater models. He serves as a technical lead and works with multidisciplinary teams on small and large sites impacted with organic and inorganic constituents, including per- and polyfluoroalkyl substances (PFAS), 1,4‑dioxane, chlorinated solvents, manufactured gas plant residual coal tar, retail service station/refinery gasoline contaminants of concern, and metals. He has worked for industrial, residential, commercial, municipal, state, and other clients under a variety of regulatory frameworks, including state-led cleanup programs such as the New Jersey Site Remediation Program and Pennsylvania Land Recycling Program (Act 2).

Mr. Swan has extensive field experience, including drilling oversight of direct push technology, hollow stem auger, sonic, air-rotary, and mud-rotary rigs to install monitoring, remediation, and injection wells; collection of soil, sediment, rock, surface water, and groundwater samples; and use of high-resolution site characterization and geophysical methods to develop CSMs. He has field experience with and engaged in technical oversight of in situ chemical oxidation, pump and treat, underground storage tank (UST) closure, excavation, ex situ chemical oxidation, soil vapor extraction, sub-slab depressurization system, and air sparging projects. In addition, Mr. Swan is well versed with ArcGIS Pro, ArcGIS Field Maps, AutoCAD, Leapfrog, spreadsheet-based and numerical models including BIOCHLOR, New Jersey Department of Environmental Protection (NJDEP) classification exception area (CEA) calculations, fate and transport modeling, Mann-Kendall analysis, and Quick Domenico.

Site Investigation

Former Dry Cleaner, Pleasantville, New Jersey Completed a preliminary assessment and site investigation for a New Jersey publicly funded soil, groundwater, and vapor contamination project at a former dry cleaning operations in a residential neighborhood. Submitted subcontractor bid packages, and developed soil, groundwater, and vapor intrusion investigation plans per NJDEP technical regulations. Obtained access to various residential properties to aid in the site investigation. Completed near-slab, sub-slab, and indoor air sampling at the former dry cleaner’s property and various downgradient residential properties. Oversaw the installation of a network of source area, upgradient, side-gradient, and downgradient shallow, intermediate, and vertical delineation monitoring wells on and adjacent to residential properties. Completed groundwater sampling and established a CEA in conjunction with a remedial investigation report submitted to NJDEP under licensed site remediation professional discretion.
Former Metal Manufacturing Facility, Sayreville, New Jersey Completed a preliminary assessment and site investigation report for a New Jersey publicly funded soil, groundwater, and vapor contamination project at a former metal manufacturing facility in a residential neighborhood. Obtained access to various residential properties to aid in the site investigation. Developed subcontractor bids based on the preliminary investigation results. Oversaw the installation of a network of source area, upgradient, side-gradient, and downgradient shallow and vertical delineation monitoring wells on and adjacent to residential properties. Completed surface and vertical soil sampling and developed stepped excavation plan based on the results of the surficial soil sampling.

Site Remediation

Former Retail Gasoline and Service Station, West Chester, Pennsylvania Oversaw the excavation and closure of former gasoline and diesel USTs and associated product piping and dispensers. Oversaw the removal of underground hydraulic lifts, former waste oil aboveground tanks, oil water separators, and French drains. Oversaw the installation of a network of source area, upgradient, side-gradient, and downgradient shallow, intermediate, and vertical delineation monitoring wells. Completed a UST closure report under Pennsylvania Storage Tank Program regulations.  Oversaw in situ chemical injections and completed quarterly groundwater sampling. Submitted remedial action progress reports to Pennsylvania Department of Environmental Protection (PADEP) case managers and Underground Storage Tank Indemnification Fund claims adjusters. Completed a remedial action completion report for groundwater under PADEP Act 2 regulations.
Former Dry Cleaner, Bensalem, Pennsylvania Completed a Phase I and Phase II environmental site assessment identifying a former dry-cleaning facility within a commercial strip mall. Oversaw the installation of a network of source area, upgradient, side-gradient, and downgradient shallow, intermediate, and bedrock delineation monitoring wells. Completed near‑slab, sub-slab, and indoor air sampling at the former dry cleaner’s property and adjacent commercial tenant spaces. Oversaw the installation of injection wells, pneumatic fracturing, and the injection of zero-valent iron to address the chlorinated solvent plume. Completed a remedial investigation report and conducted quarterly sampling with postinjection parameters.
Former Manufactured Gas Plant, Fort Washington, Pennsylvania Completed a remedial investigation of a former manufactured gas plant.  Collected soil samples to delineate the former manufactured gas plant impacts. Oversaw the installation of a network of surface and bedrock wells. Advised on a stepped excavation to remove residual coal tar from the former manufactured gas plant burn pit. Completed perimeter air monitoring during site excavation activities. Completed an ecological evaluation for the adjacent creek and the loss of vegetation during the excavation activities. Successfully excavated all former manufactured gas plant residuals and obtained a release of liability under PADEP Act 2 regulations for soil and groundwater at the site with the submission of a remedial action completion report.
Former County-Owned Property, Burlington County, New Jersey Conducted a remedial investigation of orphan tanks located on a large county property that historically contained a hospital, treatment center, prison, and juvenile detention center. Oversaw the use of surficial geophysical methods to locate former or closed-in-place USTs throughout the property.  Oversaw the soil and groundwater investigation of each UST location and advised on the installation of a network of monitoring wells to develop a remedial action. Submitted a remedial investigation report following the orphan UST investigation. Properly closed out many orphan UST locations. Developed a permit-by-rule approved by the State of New Jersey. Oversaw the installation of injection wells and the in situ chemical injection events and completed quarterly groundwater sampling. Completed a CEA, remedial action report, and remedial action permit for groundwater.

PFAS/Emerging Contaminants

Emergency Services Training Center, Burlington County, New Jersey Oversaw the dredging of a water body adjacent to an active fire training facility that historically used PFAS-containing firefighting foams. Oversaw the installation of a network of source area, upgradient, side‑gradient, and downgradient shallow, intermediate, and vertical delineation monitoring wells. Sampled groundwater for PFAS compounds using Interstate Technology and Regulatory Council and NJDEP guidance documents.
Regional PFAS Site Investigation, Camden, Gloucester, and Salem Counties, New Jersey Developed an areawide GIS and CAD database for mapping multiple counties in New Jersey with data related to correspondence with various residential and commercial properties affected by PFAS manufacturing facilities along the Delaware River. Created a series of maps detailing the sampling of residential, commercial, industrial, and irrigation wells and correspondence with various property owners. Used spatial analysis tools to target the next installation of point-of-entry treatment systems and future sampling efforts.
