Regulatory Focus: Banning land disposal of hazardous wastes

A major result of the Land Disposal Restrictions (LDR) is that all listed hazardous wastes must be treated prior to land disposal. When evaluating treatment options, generators will want to know whether the treated waste meets the Best Demonstrated Achievable Technology (BDAT) criteria for land disposal. To avoid enforcement action and penalties, analytical data must confirm that the treated waste meets BDAT criteria. Many BDAT criteria are based on the constituent concentration in the Toxicity Characteristic Leaching Procedure (TCLP) extract of the waste. Since the TCLP uses an acidic solution to leach the waste constituents, reported results may be influenced by hydrolysis, interfering compounds or laboratory contamination. Sufficient quality assurance samples must be analyzed for the data to be court defensible. This paper proposes methods for minimizing analytical problems and obtaining representative data. A case illustrates several of the problems and related solutions.

Treatment And Disposal

This paper describes the extent of the hazardous and toxic chemical waste problems in Canada and discusses the management, treatment, and disposal methods commonly used in North America and Europe. The treatment and disposal techniques covered are biological, physical–chemical, incineration technologies, and secure land disposal. Some of the available and emerging technologies for destruction of polychlorinated biphenyls are also described.
