SITE HISTORY

Discovery of gasoline contaminated soil and a UST provided the criteria for acceptance for funding by the Florida Abandoned Tank Restoration Program. Initial remedial activities included removal of an abandoned 600 gallon UST and excavation of 45 tons of petroleum contaminated soil. Pilot testing, conducted at the site, ruled out dual-phase extraction and soil vapor extraction as potential remedial approaches. Instead, the Cool-Ox® Process, a Technology based upon the long term controlled production of hydrogen peroxide in-situ, was selected. This Technology had demonstrated its ability to eradicate hydrocarbons and seemed ideal for the treatment of the clayey soils associated with this site. After one application, post treatment sampling results revealed a 95% reduction in total BTEX. Based on the results of the first treatment, a second application was approved and conducted. The current total BTEX concentrations have been reduced by >99%, over a 7-year monitoring period.

PROJECT AT A GLANCE

Remedial Objectives (Phase 1):

  1. Eliminate Soil Sources

  2. Initiate groundwater remediation

Application Method: DPT Probe Rig

Area Treated: 2,048 & 1,600 square Feet

Vertical Interval: 10 to 40 feet bgs

Injection Point (IP) Spacing: 7 ft

Media Volume Treated: 2,276 & 1,777 cubic yards

Number of Injection Points: 42 & 37

Cool-Ox® Volume: 11,400 & 10,360 gallons

Cool-Ox® per IP: 271 & 280 gal

The blue area on the site map depicts the extent of the groundwater contaminant plume prior to the first Cool-Ox® injection. The post injection site map shows the current extent and concentrations of the groundwater contaminant plume.

CURRENT STATUS

As expected, petroleum contaminant concentrations were dramatically reduced and continue to decline as a function of the long-term sustained chemical oxidation and biologic mechanisms indicative of the Cool-Ox® remedial Technology. Additional soil investigations will be conducted near MW-19 location in an attempt to identify the source of the continued low level groundwater concentrations.
