REPRESENTATIVE EXPERIENCE Remedial Investigation / Feasibility Study, Former Paul Miller Dry Cleaners Site, Staten Island, New York. Ms. Kellogg was the Project Manager for this RI/FS work assignment to investigate and mitigate contamination from a former dry-cleaning operation located in an active strip mall. The former site building is currently a fast food restaurant, so the sub-slab depressurization system (SSDS) was designed and installed to overcome the kitchen ventilation. Concurrently, Ms. Kellogg and her team used Membrane Interface Probe (MIP) technology and groundwater screening to determine the extent of the soil and groundwater contamination. They then followed with conventional monitoring wells installed at targeted locations and depths to provide a long- term monitoring network. This project required close coordination with building occupants, neighbors and managing multiple subcontractors including SSDS installers, drillers, surveyors, subsurface geophysics, analytical laboratories, data validators, and investigation derived waste transportation and disposal. Ms. Kellogg and her team are currently developing remedial alternatives. Remedial Investigation / Feasibility Study, Charlton Cleaners Site, Staten Island, New York. Ms. Kellogg was the Project Manager for this RI/FS work assignment to investigate downgradient contamination from a former dry-cleaning operation located in Dorothea Seth Kellogg, P.G. Page 3 an active strip mall. The contamination from the site has migrated beneath a strip mall and a residential neighborhood. Investigation at this site required multiple rounds of well installation and sampling to effectively delineate the horizontal and vertical extent of the plume. Ms. Kellogg and her team secured access to residential properties for sampling and well installation. They also collected indoor and sub- slab air samples from homes within the affected community. This project required close coordination with residents and managing multiple subcontractors including drillers, surveyors, subsurface geophysics, analytical laboratories, data validators, and investigation derived waste transportation and disposal. Ms. Kellogg and her team are currently developing remedial alternatives. Remedial Investigation / Feasibility Study, Former Red Devil Paint Site, Mount Vernon, New York. Ms. Kellogg was the Project Manager for this complicated RI/FS work assignment. CDM Smith investigated an off-site polyurethane-related LNAPL with an associated dissolved phase groundwater plume, which involved coordination with the Brownfields Responsible Party (BRP) conducting the onsite investigation and remedial action. Ms. Kellogg reviewed documents submitted by the BRP to assess data gaps for the offsite investigation. To successfully develop remedial alternatives, Ms. Kellogg and her team had to evaluate the unique chemical and physical properties of the polyurethane LNAPL. This included unique laboratory analysis, treatability testing and bench-scale studies. The site location is isolated between the Bronx River and the Metro North Railroad and is considered critical habitat by New York State Fish and Wildlife Service (NYSFWS), which limited remedial alternatives. Remedial Design / Remedial Action, Former Red Devil Paint Site, Mount Vernon, New York. Ms. Kellogg was the Project Manager for this complex RD/RA work assignment. The remedial objective was to prevent the LNAPL from entering the Bronx River. NYSDEC selected a containment wall as the remedial alternative. Due to the inaccessibility of the project site, construction of the containment wall was estimated at $1,000,000. Ms. Kellogg and her team conducted hydrologic modeling to determine if the containment wall would alter the groundwater flow and cause the LNAPL to flow around the wall. At the recommendation of CDM Smith, the model also included historic LNAPL thicknesses and results showed that the LNAPL thickness was reducing because of the BCP activities and would have dissipated prior to the containment wall being completed. This resulted in NYSDEC revising the remedy to Long Term Monitoring and a cost savings of $1,000,000 for NYSDEC. Remedial Investigation / Feasibility Study, Pride Solvents and Chemical Site, West Babylon, New York. Ms. Kellogg was the project manager for this RI/FS. Prior to the field investigation, Ms. Kellogg and her team, reviewed twenty years’ worth of historical site Dorothea Seth Kellogg, P.G. Page 4 documents to identify data gaps and develop a phased approach to determining the nature and extent of contamination at the site. Ms. Kellogg and her team employed a Triad-like approach to the field investigation, using an on-site laboratory and evaluating soil and groundwater screening data in real-time to evaluate the vertical and horizontal extent of contamination. Ms. Kellogg planned the field investigation to occur concurrently with the investigation at the Villa Dry Cleaners Site. By conducting the field investigations concurrently, Ms. Kellogg reduced the cost of the investigation. The results of the investigation showed there was residual shallow contamination beneath the site buildings and an extensive deep groundwater plume with the highest contaminant concentrations just above a confining clay layer at 90 feet bgs. Ms. Kellogg and her team developed remedial alternatives for this site and NYSDEC selected AS/SVE for the shallow groundwater and in-situ bioremediation for the deep groundwater.
