Michael S. Kozar, PG, LSRP, LRS

Michael Kozar is an Operations Manager and Principal Hydrogeologist at Roux. He is a registered Professional Geologist in Pennsylvania, a Licensed Site Remediation Professional (LSRP) in New Jersey, and a Licensed Remediation Specialist (LRS) in West Virginia, with thirty-five years of experience in environmental assessment, feasibility studies/remedial evaluations, implementing remedial solutions, providing multidisciplinary project direction, and regulatory communications. He has extensive experience with soil and groundwater characterizations and ex situ/in situ remediation techniques in a variety of hydrogeologic environments. He has directed CERCLA/Superfund and State-lead programs for major industrial/commercial clients and complex sites throughout Pennsylvania, New Jersey, Maryland, West Virginia, and other US Regions.

• Project Director/Lead Hydrogeologist for Superfund Projects, USEPA Regions 2 and 3. Mr. Kozar has led and performed Remedial Investigation (RI), Risk Assessment (RA), Feasibility Study (FS), Remedial Design and Pre-Design Investigation (RD/PDI), and Remedial Action (RA) services for numerous CERCLA/Superfund sites predominantly in Pennsylvania, New Jersey and Maryland, as well as in South Carolina and New York. He has implemented established and innovative characterization and remediation methods including multiple Superfund projects employing in situ bioremediation of groundwater including dense non-aqueous phase liquid (DNAPL); groundwater pump and treat; soil vapor extraction (SVE); in situ thermal treatment (ISTT); groundwater amendment/reinjection; in situ chemical reduction (ISCR); and monitored natural attenuation (MNA).
• ISRA/Spill Act and LSRP Services, Numerous Sites, New Jersey. Mr. Kozar’s experience includes numerous environmental site characterizations, soil and groundwater investigations, and remediation projects under New Jersey’s Industrial Site Recovery Act (ISRA) and Spill Compensation and Control Act (Spill Act), including serving as the retained LSRP on many projects. His work has included all regulatory phases while managing teams for complex environmental investigations, natural remediation evaluations, enhanced bioremediation for hydrocarbons and chlorinated solvents in groundwater, groundwater recovery/pumping well design, and remedial performance evaluations for fractured and porous media.
• LSRP of Record for Sediment, Soil, and Groundwater Remediation, New Jersey. Project Director/LSRP for Remedial Design (RD)/Remedial Action (RA) at former glass manufacturer. The sediment and upland soils investigation/RA were conducted to address NAPL, metals, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs). The PCB cleanup was conducted satisfying New Jersey Department of Environmental Protection (NJDEP) and United States Environmental Protection Agency (USEPA) requirements, including Toxic Substances Control Act (TSCA) regulations. The RA work also addressed historic fill material (HFM) and groundwater inorganic impacts via MNA. An Ecological Risk Assessment (ERA) was also completed for contaminants in soil and sediment, which involved obtaining NJDEP ecological group approval for soils to remain in place and 3for alternate remediation standards for soil and the ecological pathway. A NAPL-impacted soil excavation was also completed.
• Site Assessment/Risk Assessment for Former Chemical Manufacturing Site, West Virginia. Mr. Kozar served as Project Director and Principal Hydrogeologist for the groundwater and sediment/surface water characterization on a site bordered by a regional river and designated an alternate drinking water supply. Various site investigation activities were completed to characterize on-site and off-site impacts caused by previous operations. These impacts include chlorinated solvents such as carbon tetrachloride, tetrachloroethene, trichloroethene, and benzene hexachloride (BHC). The completed site assessment included sediment and upland soil coring and sampling; surface water sampling; bedrock groundwater investigation; off-site soil vapor and vapor intrusion (VI) investigations; benthic/mussel surveys; and fish tissue sampling. Mr. Kozar led the evaluation of the extent of DNAPL in the fine-grained unit, sand, and bedrock zone. As part of the river investigation, water samples were collected from the hyporheic zone of the river to further characterize contaminant concentrations in the groundwater-surface water mixing zone, and to assess human and ecological receptors. A human health risk assessment was completed, and ecological screening and risk characterization were conducted to assess data gaps for further study, including the development of a Mussel Toxicity Assay Workplan using West Virginia Department of Environmental Protection (WVDEP)/United States Army Corps of Engineers (USACE) methodology. Mr. Kozar also presented at public advisory group meetings as well as numerous WVDEP meetings.
• Project Manager for Former Steel Plant Brownfields Redevelopment/RCRA and Act 2 Project, Pennsylvania. Responsible for providing hydrogeological expertise for schedule-driven RI/cleanup plan as part of the redevelopment of a 500-acre former industrial site, successful completing the cleanup under Pennsylvania’s Land Recycling and Environmental Remediation Standards Act (Act 2) and the Resource Conservation and Recovery Act (RCRA) under USEPA Region 3. Involved fast-track implementation of field program, data reporting, and close coordination with the Pennsylvania Department of Environmental Protection (PADEP) and USEPA. The Act 2 baseline/final report and RCRA decision documents were approved for the Site by PADEP/USEPA Region 3 and an Act 2 release of liability was achieved for the Site.
