56 BIO-ENHANCED THIN-SPREADING: A LOW COST SOIL REMEDIATION ALTERNATIVE Gene Wong, Staff Civil Engineer Richard Pfarrer, III, Supervisor, Environmental Remediation Kohler Company Kohler, Wisconsin 53044 INTRODUCTION Kohler Company is a world-wide manufacturer of commercial and residential plumbing products, small gasoline engines, electrical generators, fine furniture, and other household goods. Kohler Company's largest manufacturing facility is located at the corporate headquarters in Kohler, Wisconsin where approximately 5,500 people are employed. Products manufactured at Kohler Company's Kohler, Wisconsin plant include a variety of plumbing fixtures, including vitreous china toilets and sinks, cast iron enameled sinks and tubs, electroplated faucets, assorted plumbing fittings, and small engines. This paper focuses on a soil remediation project performed at the Kohler Company's Kohler, Wisconsin facility. In order to implement this soil remediation project, close coordination and communication was required with many project entities including numerous company departments, contractors, regulatory agencies, and the general public. Using an innovative and cost- effective soil treatment method called bio-enhanced thin-spreading (BETS), over 5,000 cubic yards of kerosene-contaminated soils were successfully remediated. The purpose of this case study is: 1. To describe the technical aspects of the remediation project including the BETS soil treatment method; and 2. To discuss factors which can significantly influence the development, management, and implementation of environmental remediation projects at large manufacturing facilities. REMEDIATION PROJECT PROCESS All remediation projects, whether they are small leaking underground storage tank (UST) sites or multi-million dollar Superfund sites, go through a basic step-by-step process. This process, broken down to its simplest form, consists of the following steps: site discovery, site investigation, alternatives evaluation and selection, remedial design, and remedial action. Descriptions of the specific steps taken to implement and complete the kerosene-contaminated soil remediation project are presented in the following sections. An overall project schedule is presented in Figure 1. Site Discovery On September 11, 1990. petroleum contaminated soils were observed in an excavation being performed for a sewer line project at the Kohler Company manufacturing facility. The excavation zone was in a high traffic area surrounded by railroad tracks and several manufacturing buildings. Figure 2 shows the location of the contaminated soils within the facility grounds. Research into the historical operations of the plant indicated that two USTs (23,000-gallons and 1,500-gal- lons) had formerly been located within the vicinity of the excavation. These USTs, which had been used to store kerosene and were the likely contaminant source, were installed in the early 1950s and removed in 1984. 50th Purdue Industrial Waste Conference Proceedings, 1995.
