CROWtm FIELD DEMONSTRATION WITH BELL LUMBER AND POLE

PDF Version Also Available for Download.

Description

In 1990, efforts were initiated to implement an in-situ remediation project for the contaminated aquifer at the Bell Lumber and Pole Company (Bell Pole) site in New Brighton, Minnesota. The remediation project involves the application of the Contained Recovery of Oily Waste (CROW{trademark}) process, which consists of hot-water injection to displace and recover nonaqueous phase liquids. While reviewing the site evaluation information, it became apparent that better site characterization would enhance the outcome of the project. Additional coring indicated that the areal extent of the contaminated soils was approximately eight times greater than initially believed. Because of the uncertainties, in ... continued below

Description

In 1990, efforts were initiated to implement an in-situ remediation project for the contaminated aquifer at the Bell Lumber and Pole Company (Bell Pole) site in New Brighton, Minnesota. The remediation project involves the application of the Contained Recovery of Oily Waste (CROW{trademark}) process, which consists of hot-water injection to displace and recover nonaqueous phase liquids. While reviewing the site evaluation information, it became apparent that better site characterization would enhance the outcome of the project. Additional coring indicated that the areal extent of the contaminated soils was approximately eight times greater than initially believed. Because of the uncertainties, in 1993, a pilot test was conducted that provided containment and organic recovery information that assisted in the design of the full-scale CROW process demonstration. After reviewing the cost ramifications of implementing the full-scale CROW field demonstration, Bell Pole approached Western Research Institute (WRI) with a request for a staged, sequential site remediation. Bell Pole's request for the change in the project scope was prompted by budgetary constraints. Bell Pole felt that although a longer project might be more costly, by extending the length of the project, the yearly cost burden would be more manageable. After considering several options, WRI recommended implementing a phased approach to remediate the contaminated area. Phase 1 involves a CROW process demonstration to remediate the upgradient one-third of the contaminated area, which contains the largest amount of free organic material. The Bell Pole Phase 1 CROW demonstration began in mid-1995 and was operated until January 2001. The operation of the demonstration was satisfactory, although at less than the design conditions. During the demonstration, 25,502,902 gal of hot water was injected and 83,155 gal of organics was transferred to the storage tank. During operations more than 65% of the produced organic material was used in Bell Pole's treating operation. Additional quantities of the material have been used since termination of the Phase 1 injection. Recycling the produced organic material has partially offset the cost of remediation.
