Jacques Cartier St Park

7/2009-present

 

This project was performed at Jacques Cartier State Park near the St. Lawrence River in Morristown, NY. The New York State Office of Parks, Recreation and Historic Preservation asked OP-TECH to perform a pilot study in 2004, which developed into a larger project to reduce concentrations of volatile organic compounds in both the soil and groundwater.


OP-TECH's work on this project included the design and installation of a multi-phase extraction (MPE) system to remove and treat contaminated groundwater and evacuate petroleum vapors in soil and bedrock voids. OP-TECH added additional extraction wells to it's 2004 pilot study infrastructure which was successful in reducing groundwater and soil vapor VOC concentrations.


The MPE system was shut down in August of 2006 when concentrations of VOC in groundwater samples represented the stagnation of the effectiveness of the MPE process, when the relationship between time, effort and cost and the diminishing results from continued MPE efforts. OP-TECH prepared and implemented a natural attenuation work plan approved by the New York State Department of Environmental Conservation to monitor the site for a period of one year at which time additional reductions in VOC concentrations led to closure of the spill.
