Groundwater Contamination/Remediation
Confidential Client, New York
J. Robert Folchetti and Associates (JRFA) provided over 100 local site assessments along with initial subsurface investigation to determine the source of dry cleaning solvent (perchloroethylene) contamination of a local drinking water system.
After completion of the initial investigation, JRFA provided design and construction administration services for a 60,000 GPD Granular Activated Carbon Filtration System for the local drinking water supply. As designed and operated, this system has continuously treated highly contaminated water to below the New York State Drinking Water Standards for the containment of concern.
Final subsurface investigation determined that the contaminant source concentration was 4,500,000 mg/l. The maximum contaminant level for perchloroethylene, as described in the New York State Drinking Water Standards is 0.5 mg/l. JRFA was retained to conduct a CERCLA Feasibility Study, under New York State Department of Environmental Conservation oversight, to determine the fastest, most efficient, and most cost effective method of remediating this site.
Services provided included the following:
Complete interim remedial measure design, plans, and specifications
Developed remediation objectives
Developed groundwater model
Identified remedial technologies for soil, groundwater, and air
Assembled applicable technologies into site-wide remedial alternatives
Analyzed site-wide alternatives for: effectiveness; protection of human health/ environment; implementability; and cost
Preliminary design of all unit processes for all technologies in each site-wide alternative
Project schedule and budget
The project was completed on time and within the established budget.
