The Client reported oil/water mixture within a pit in the basement, located in the vicinity of a former boiler. Hydro Tech performed remedial activities at the above property under direct oversight of the NYSDEC in order to address the petroleum spill at the property. The remedial activities included the removal of the oil/water mixture from the basement followed by the installation of monitoring and recovery wells. Weekly Enhanced Fluid Recovery (EFR) events were performed for over a span of six months. The inactive boiler was abandoned in place with approximately 1,500 gallons of foam on May 22, 2007. Oxygen Releasing Compounds (ORCs) were injected in the vicinity of the wells and monthly groundwater monitoring was continued as part of the remedial efforts. A Vapor Intrusion Survey was performed and no possible impacts were noted on neighboring properties. The NYSDEC closed Spill # 0511521 on November 28, 2007.

The project located at 402 Avenue U was successfully entered into the Brownfield Program during December 2007. Hydro Tech will now supervise the construction while remediating both the petroleum contaminated soil and groundwater associated with the site.

Lawrence Aviation Industries, Inc. (LAI) site in Port Jefferson Station, Suffolk County, New York was an active manufacturer of titanium sheeting for the aeronautics industry. It is currently listed on the National Priority List (NPL) for numerous violations. Numerous areas of concerns exist at the site. At the request of the NYSDEC, Hydro Tech is currently undertaking the remediation of hazardous wastes from the property. This includes the removal of petroleum and PCB contaminated liquid from all machine pits, soil contaminated with volatile organic compounds and PCBs and all transformer pads containing PCBs. All petroleum storage vessels will be removed from Site. All petroleum stained areas have already been cleaned by Hydro Tech.

Hydro Tech has prepared and submitted a Remedial Action Plan (RAP) to the New York State Department of Environmental Conservation (NYSDEC) for the tasks associated with the UST removals. A separate RAP was prepared and submitted to the Nassau County Department of Health (NCDOH) to address the storm water drywells and floor drains at the Site. Ten drywells have been properly remediated under the direct oversight of the NCDOH and a Hydro Tech geologist. Eight (8) USTs have been removed and contaminated soil was excavated and disposed of. The excavated areas have been backfilled with clean soil allowing for the final restoration of the excavation areas. As per the NYSDEC recommendation, five (5) monitoring/recovery wells have been installed at the site and a monthly monitoring program has been instituted.
