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 foodrestaurant, so the sub-slab depressurization system (SSDS) was designed and installed toovercome 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 withconventional monitoring wells installed at targeted locations and depths to provide a longterm 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, andinvestigation derived waste transportation and disposal. Ms. Kellogg and her team arecurrently developing remedial alternatives.
Remedial Investigation / Feasibility Study, Charlton Cleaners Site, Staten Island, NewYork.
Ms. Kellogg was the Project Manager for this RI/FS work assignment toinvestigate downgradient contamination from a former dry-cleaning operation located inDorothea Seth Kellogg, P.G.
Page 3an active strip mall. The contamination from the site has migrated beneath a strip malland a residential neighborhood. Investigation at this site required multiple rounds of wellinstallation and sampling to effectively delineate the horizontal and vertical extent of theplume. 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 wastetransportation 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 anassociated dissolved phase groundwater plume, which involved coordination with the
Brownfields Responsible Party (BRP) conducting the onsite investigation and remedialaction. Ms. Kellogg reviewed documents submitted by the BRP to assess data gaps forthe offsite investigation. To successfully develop remedial alternatives, Ms. Kellogg andher team had to evaluate the unique chemical and physical properties of the polyurethane
LNAPL. This included unique laboratory analysis, treatability testing and bench-scalestudies. 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 theinaccessibility 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 becauseof 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 anda 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.

documents to identify data gaps and develop a phased approach to determining the natureand extent of contamination at the site. Ms. Kellogg and her team employed a Triad-likeapproach to the field investigation, using an on-site laboratory and evaluating soil andgroundwater screening data in real-time to evaluate the vertical and horizontal extent ofcontamination. Ms. Kellogg planned the field investigation to occur concurrently with theinvestigation at the Villa Dry Cleaners Site. By conducting the field investigations
concurrently, Ms. Kellogg reduced the cost of the investigation. The results of theinvestigation 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. Field Manager for insitu soil characterization as part of RAP implementation for a one-acre brownfield site
