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.

SUMMARY OF EXPERIENCE
 
Superfund Investigations
Supervised several groundwater and soil investigations for radionuclide and metals contaminated media at Brookhaven National Laboratory. Also provided laboratory technical support for the analysis of mercury and radionuclides at a federally-funded field laboratory at Brookhaven National Laboratory.
 
State Petroleum-Impacted Sites
Performed fluid-level gauging, groundwater sampling, and has written reports for numerous New York State Department of Environmental Conservation Regions 1 and 2 projects in Suffolk, Nassau, Queens, Brooklyn, Bronx, and Manhattan, NY. Also wrote several investigation work plans, remedial action plans, and summary reports for the New York State Department of Environmental Conservation Region 2.
Performed monthly and quarterly groundwater sampling at petroleum-impacted residential and municipal properties in New York.
Also performed soil-vapor intrusion sampling at several petroleum-impacted sites for and in the presence of county and state agency representatives.
 
Phase I and II Environmental Site Assessments
Performed numerous Phase I environmental site assessments in New York, New Jersey, Pennsylvania, and Delaware for property transfers and refinancing. In cases when Phase I report conclusions recommended additional work be performed to evaluate the potential for contamination at the site, a Phase II investigation was performed which may have included air, soil, soil-vapor, groundwater, or drinking water sampling, groundwater flow direction determination, investigation of upgradient potential sources of contamination, and in some cases, remediation of identified contamination.
 
Commercial, Residential, and Municipal Drinking Water Sampling
Performed drinking water sampling at several commercial and residential properties located in New York and New Jersey, and also for several Long Island schools for numerous suites of compounds.
 
Petroleum and Underground Storage Tank Investigations
Performed evaluations of UST leakage at numerous sites. The evaluations included soil and soil-vapor 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, or excavation of contaminated soil and removal of free-floating petroleum form the water table surface.
