SUMMARY OF EXPERIENCE
Water Resources Management Plan
Mr. Dermody
was the primary author of the Town of East Hampton Water Resources Management Plan, which was prepared in 2004. He evaluated
past water-use trends and future water-use projections. Also, various issues relating to the quality of groundwater in the
Town of East Hampton were evaluated including USTs, non-point sources of nitrogen, and recommendations for restrictions on
certain commercial properties in sensitive groundwater sites.
Superfund Investigations
Performed Remedial Investigations/ Feasibility Studies including consent order and work plan
negotiations, work plan preparation, field investigations, data analysis, evaluation and selection of remedial alternatives
at over 20 sites including New York sites in Westbury, Mattituck, Lindenhurst, Springs, Montauk, Farmingdale, New Cassel,
Bay Shore, and Bronx, and at a New Jersey site in Jobstown.
Environmental Impact Statements
Performed analysis of the feasibility of supplying the East Hampton Airport with sufficient supply of water
for fire-fighting purposes. The proposed action entailed the installation of a Suffolk County Water Authority pipeline. The
project entailed the calculation of fire fighting water requirements for the airport, calculation of head losses along the
proposed course of the pipeline, and analysis of the impacts of increased pumpage on saltwater intrusion. The project also
considered the potential impacts to surface water bodies, wetlands, and the ecology of the project area.
Performed
an Environmental Impact Statements to determine the most technical and economically feasible method of providing potable water
to a residential community on Long Island. The community, which had been served by private wells, was impacted by a spill
of tetrachloroethylene that contaminated a number of private wells. Evaluated the direction of the plume migration, emergency
measures such as bottled water and individual treatment system, and long-term solutions including importing public water and
creation of a community water supply system. Groundwater modeling was employed to assist in the determination of the most
feasible alternative.
Petroleum and Underground Storage Tank Investigations
Performed evaluations of UST leakage at numerous sites. The evaluations included soil contamination analysis,
groundwater well installation, sampling, and interpretation of results. Work plans were prepared and negotiated with the appropriate
regulatory agency to determine the scope of work and objectives at each site. Soil and groundwater remediation was performed
at numerous sites including soil vapor extraction, air sparging, bioremediation, or excavation of contaminated soil and removal
of free floating petroleum from the water table surface.
Supervised hydrogeologic and water quality studies at
several former manufactured gas plant sites. Work included determining typical levels of coal tar components dissolved in
groundwater, comparison of dissolved coal tar component levels to levels of dissolved components of other hydrocarbon products
at the sites, and DNAPL migration of coal tar.
Hydrogeological Investigations
Mr. Dermody performed and interpreted data for aquifer pump tests to provide data for dewatering and water
supply projects in Manhattan, Queens, and Brooklyn, Nassau and Suffolk Counties.
Also, performed a water supply
analysis for a vacation resort in central California. The analysis included the delineation of the watershed area, estimates
of the groundwater reservoir, analysis of water usage, and the preparation of recommendations to be implemented to assure
a plentiful, high-quality supply of potable water for the future.
Landfills
Performed landfill closure investigations including the installation and sampling of groundwater
and methane monitoring well networks, hydraulic conductivity analyses, infrared aerial photography analysis, groundwater flow
modeling, and analysis closure requirements including landfill capping and capping alternatives, landfill reclamation, and
post-closure monitoring as per the requirements of 6NYCRR Part 360 regulations. Analysis was performed at landfills at Fishers
Island, Montauk, East Hampton, and Orange County, New York.
Vapor Intrusion Investigations
Mr. Dermody performed several vapor intrusion investigations for the collection of soil
gas and indoor air samples according to the recently adopted protocols as established by the New York State Department of
Health and NYSDEC.
