2018 Battelle Conference Acceptance

Equipoise is please to announce that our abstract, submitted by Mr. Steven Pitts, on Environmental Fracturing in Low-K Conditions to Enhance Soil Vapor Extraction was accepted for the 11th International Battelle Conference on Remediation of Chlorinated and Recalcitrant Compounds that will be held April 8th – 12th in Palm Springs, California.

Background/Objectives. The soil and soil gas at a former industrial facility in California (The Facility) are impacted with volatile organic compounds (VOCs) including trichloroethene (TCE). Soil vapor extraction (SVE) and two-phase extraction (TPE) systems have operated for several years at the Facility; however, VOC recovery rates with the current SVE/TPE well system have reached asymptotic conditions. This is a function of extended remediation operations at each SVE/TPE well and low effective porosity conditions comprised of friable to moderately indurated sandstone with varying degrees of cementation. The Environmental Fracturing (EF) technology was implemented at the Facility to increase air flow within the unsaturated zone and enhance the performance of the existing SVE/TPE systems.

Former Pacific Treatment Site Cleanup & Closure

Equipoise achieves no further action finding and closure of the former Pacific Treatment site, a former hazardous waste storage and treatment facility, located at 2190 Main Street, San Diego, California.

In May 1986, an unauthorized release case was opened  when a tar-like product was observed in the excavation during the removal of four underground storage tanks that reportedly stored diesel. Soil sampling conducted after the tank removal showed low concentrations of petroleum hydrocarbons.

Groundwater monitoring was conducted from June 1996 until June 25, 2015.  Free product removal methods previously conducted at the site by prior consultants, which included: purging with a bailer, purging with a vacuum truck, absorbent socks, passive and active skimmers, and dual phase vapor extraction, were ineffective.

In 2014, Equipoise successfully implemented a full-scale bioslurping remediation plan—a method which combines vacuum assisted product removal with soil vapor extraction to simultaneously remove product and remediate soil vapor—using the existing monitoring well network resulting in the closure of the site.  For more information follow the link below.
