Abstract : Certain hazardous chemical spills are soluble in water and may persist in the water column for long periods of time. In some cases, adverse environmental impacts of such spills may be ameliorated by a response method which either removes a major portion of the spilled chemical or which converts the chemical to a less harmful species. In this program, the feasibility of four types of chemical treatment has been assessed for the amelioration of the effects of hazardous, water-soluble chemical spills. These treatments are: Neutralization, Solvent Extraction, Precipitation and Chelation. For each technique, the treatment chemistry was studied, potential methods of application of the treating agent were evaluated and the environmental fate and consequences were assessed for the treatment options, including the possibility of misapplication of treating agent. In addition, future requirements for additional research and development needed to implement actual field response techniques and equipment are projected for each treatment method.
