Threats and Contaminants: Wood treatment activities at the Site resulted in the production of creosote-contaminated sledges, sediments, process residuals, preservative drippings, and spent process liquid. A review of historical information revealed that, during its operation, the facility treated railroad ties and telephone poles with creosote and discharged the excess via canals to two lagoons located on the Site. The creosote material discharged into these lagoons was not removed prior to the development of the property for residential and commercial use in the mid-1960s. The Claremont Development residential community and the Rustic Acres Mall were built over much of the former facility property. During construction of the Claremont Development, soil was deposited on top of the lagoons. One lagoon lies 2-3 feet below the soil surface and the other lagoon lies 8 -10 feet below the soil surface. The shallow lagoon extends approximately16 feet below ground surface while the other extends over 25 feet to bedrock. At several properties, the former lagoons abut or underlie existing residences. The material in the lagoons is a concentrated creosote sludge; on at least one occasion, creosote sludge seeped into a residential basement sump and was pumped out into the storm sewer. The former canals are shallower – extending approximately 4-8 feet below ground surface. The material in the former canals is, for the most part, a dry, crusty creosote/soil mixture. As a very rough estimate, the lagoons and canals contain approximately 40,000 cubic yards of source material.
