Client:       Petrochemical Company

Project:     Remedial Cleanup Via An Alternative Analysis

Location:  New Jersey

  

 

 

 Description:  A leading petrochemical company hired EWMA to address an environmental concern located on their property.  Soil and ground water were contaminated by volatile organic compounds (VOCs) from leaking gasoline underground storage tanks (USTs).  Over a period of years, previous consultants had installed ground water monitoring wells throughout the property to delineate the VOCs.  Based on the delineation activities, the other consultants proposed a ground water pump and treatment system to address the contamination, which would have cost the client approximately seven hundred and fifty thousand dollars ($750,000).

EWMA’s review of the case revealed that many of the monitoring wells were improperly constructed, piercing numerous confining strata.  The improperly constructed wells had facilitated vertical contaminant migration and highly variable ground water flow patterns. The flow patterns prompted the New Jersey Department of Environmental Protection (NJDEP) to call for even more contaminant delineation.

 
EWMA proposed additional soil removal near the former tanks, followed by ground water monitoring only.  The additional soil removal resulted in a reduction of ground water contaminant levels to below NJDEP standards within two months, eliminating the previous requirement for a costly pump and treatment system

As a result of EWMA’s alternative analysis regarding the remedial cleanup of the contamination at the property, EWMA completed the remedial work at the site for less than three hundred and twenty five thousand dollars ($325,000), which was less than half of the original remedial cleanup cost estimate.
