Central New Jersey

Project at a Glance:

• Multi-faceted ISRA project at a specialty chemical company located in central New Jersey.
• Use of SVE technology was conducted to remediate the accessible areas of soil contamination.
• Whitman planned and conducted the remediation with minimal disruption to plant operations.
• Other issues included lead-contaminated soils, contamination from historic uses, an AST farm, and potential ground water contamination.

This multi-faceted ISRA project is unique due to the extensive amount of investigation and remediation conducted while the property maintained its industrial operations. Areas investigated include:

• Tank farms (AST/UST)
• Soil contaminated with Volatile Organics, Polynuclear Aromatic Hydrocarbons, and Lead
• Ground water contamination

Investigation

To meet requirements for a potential sale of the property, Whitman conducted extensive pre-ISRA soil sampling to identify site concerns and potential remedial costs. These activities were conducted within a short time period and allowed the timely transfer of the facility to occur.

The comprehensive ISRA investigation revealed various forms of contamination at several areas, many of them being of a historic nature that pre-dated the Client’s operations. Through research of available documents concerning surrounding areas and evaluation of local hydrogeological conditions, Whitman was able to identify off-site sources of contamination to the on-site ground water.

Remediation

Whitman implemented a variety of remedial methods throughout the site, according to the type of location of contamination, with little or no disruption to on-going industrial operations.

Lead-contaminated soil was excavated and transported for off-site treatment and disposal at substantial cost savings over untreated soil disposal costs. Contaminated soil in another area was excavated by hand and transported off site for incineration.

At the AST farm area, an SVE and dewatering trench system is being utilized to remediate the volatile organics contamination in this area.

Ground water monitoring has been initiated to evaluate the effectiveness of the source control measures that are being implemented.

A pilot test of soil vapor extraction (SVE) with steam injection is conducted.

Excavation of gasoline-contaminated soil derived from historic site operations as a lumber yard. Excavation occurred in an active drum storage area with special controls to protect the area from potential discharges.
