Problem:  -Plume length greater than 300 feet
                 -Contamination extended off-site on to two neighboring properties
                 -Groundwater pumping rates to control plume projected to be in excess of 100 gpm
 
Project Objective:    Achieve cost effective closure of off-site properties without restrictions
 
Solution:  -Enhance natural attenuation using an oxygen release material
                 -Reduce duration of monitoring
                 -Reduce cost and time

Results are shown below

 

 Results:  After 22 Months Source area Ethylbenzene concentrations have been reduced by 100%.  Source area Xylene concentrations have been reduced by 100%.  Total Ethylbenzene mass has been reduced by 95%.  Total Xylene mass has been reduced by 96%.  The site can be Closed  with restrictions.  No off-site restrictions are necessary.

Total Installation Cost:  $14,300
