Abstract
Various silicone materials, which have a low order of toxicity to fish, birds, and wildlife; and which slowly degrade to carbon dioxide and silicon dioxide in the environment, may be used to treat local soils to make them permanently oleophillic. These soils can then be used to minimize, consolidate, and clean up oily spills. Because local soils are used and only minor amounts of chemicals are required, the cost of cleanup is drastically lowered while response time is much quicker.
