Joseph Duminuco, PG

Executive Vice President Principal Hydrogeologist

Mr. Duminuco has over thirty-five years of experience, including Executive Vice President, Vice President, Director of Site Investigation and Remediation Services, Brownfields Practice Area Leader, and Office Manager of Roux. His expertise involves providing environmental consulting services and strategic planning to the real estate industry focused on Brownfield Redevelopment projects. His experience also extends to investigation and remediation of soil, groundwater, soil vapor, and contaminated building materials at industrial sites, focusing on the use of innovative solutions.

representative projects
  • Principal-in-Charge of a NYSDEC BCP redevelopment of a property adjacent to a dry cleaning solvent distribution facility. The Site was a former freight railyard, and offloading spillage onsite and migration from the offsite solvent facility resulted in significant soil, groundwater, and vapor contamination with chlorinated VOCs. The Site was developed into multifamily units with first floor retail use and the remedy consisted of soil hot spot removal, a physical barrier to limit onsite migration, a permeable reactive wall to eliminate offsite migration, hot-spot in situ injections, and a sub-slab depressurization system.
  • Principal-in-Charge of a NYSDEC BCP redevelopment project with a RCRA-compliant facility closure. The Site is a former paint factory. Historical site operations adversely impacted the subsurface, including a LNAPL plume, in addition to petroleum hydrocarbon impacts to the soil and groundwater. Roux completed a RI at the Site which characterized the nature and extent of the impacts. The remedial action included a large excavation that required SOE and was completed under a tent due to odor concerns, multiple ISCO injections, UST removal/abandonment, installation of an LNAPL recovery system, and installation of an SSDS. Additionally, Roux provided oversight of RCRA closure activities at the Site which included emptying, cleaning, and scrapping 65 ASTs/vessels, and decontaminating the ceilings, walls, and floors of the Paint Factory Building and collection of compliance samples.
  • Principal-in-Charge of a NYSDEC VCP redevelopment of a former MGP site into a big-box retail site. The Site is located along the Gowanus Canal Federal Superfund site. Roux negotiated with the NYSDEC and limited remediation to former gasholders filled with coal tar, soil hot spots with mobile coal tar, and perimeter containment of coal tar. All the remaining soil at the Site was impacted with MGP waste and most of the Site was underlain by liquid coal tar. Roux negotiated the use of institutional/engineering controls to allow significant contamination to remain in place. A set of passive perimeter recovery wells, sub-slab depressurization system and vapor barrier were installed to address the mobile coal tar left below the retail building.
  • Principal-in-Charge for a NYSDEC BCP redevelopment project at a site which consists of 16 separate parcels spanning 4.5 acres, and had a variety of former commercial uses including automotive service/repair and multiple dry cleaners. The Site has both chlorinated solvent and petroleum hydrocarbon impacts to the soil, groundwater, and soil vapor. The remedy will consist of a site cover system, soil hot spot removals, in situ chemical oxidation for groundwater contamination, and installation of a sub-slab depressurization system.
  • Principal-in-Charge of multiple dry cleaner remediation project takeovers in NYC, Long Island, New Jersey, and Connecticut. Sites included a mixed-use affordable housing/retail complex, a healthcare facility, and multiple retail shopping centers. Impacts included soil, groundwater (bedrock and overburden), surface water, soil vapor, indoor air, and building material contamination from chlorinated VOCs. Remediation activities included hot spot soil removal, AS/SVE, in situ groundwater treatment, and SSDS installations.
