Cleanup reduced to one-fourth of its original size using chemical oxidation. Groundwater concentrations were substantially reduced and the more challenging free-product was also effectively treated from a baseline of 0.05 feet to less than 0.01 feet. PE Steve H.

A total of nine injection events over 10 months reduced the remediation costs by about 75 percent. cated a significant reduction in the area of impacts as compared to baseline observations. After the ninth injection event, the two highly contaminated shallow soil areas (10,000 ppm TRPH) were reduced in size by 75 percent, from a baseline footprint area of 480 sq. feet to an area of 120 sq. feet. The relatively less contaminated soil area (2,000 ppm TRPH) was reduced in size by 79 percent, from a baseline footprint area of 3,953 sq. feet to an area of 858 sq. feet. Overall, the area of impacted soil was Visit www.pollutionengineer.com to electronically forward a copy of this article to a colleague or customers.
