J.S. Ilirschhorn (Congressional Office of Technology Assessment) as early as 1988 presented a scholarly summary of waste reduction as the ultimate key to pollution abatement, Waste reduction is the only way to save industry some of tire escalating costs of the current waste-management system. The direct costs of waste disposal have increased some 50 times just over the past few years. Hirschhorn listed six steps to waste reduction ... 

As an extraction technique, SFE proved to give comparable recoveries to those of Soxhlet extraction. In all cases, SFE dramatically shortened extraction times and minimized most environmental hazards, solvent concentration steps, and waste disposal costs. A summary of this comparison is included as Table XII and is a projected cost comparison of SFE to Soxhlet extraction, based on our experiences with the SFE system used in these studies (Isco SFE System 1200). The projected cost per extraction was determined to be 15.85(SFE) vs. 22.60(Soxhlet). 

After carrying out WASTOXHAS, decision-makers can choose to dispose solid wastes in the environment with (or without) treatment (for a review see Conner and Hoeffner, 1998) or continue waste hazard assessment with more sophisticated ecotoxicological approaches like microcosm (Pollard et al., 1999) or mesocosm (Propst et al., 1999) approaches taking into account the waste disposal scenario. A summary of the complete procedure is provided in Table 1. 

These summaries will become part of the DQA statement. The chemist reviews waste disposal data, but does not tabulate it. Based on results of analysis, waste streams are profiled and shipped to the disposal facility under appropriate manifests.

A good summary of the status of radioactive waste disposal in tiie United States can be found in an article by John R. Vincenti, Low-Level Radioactive Waste Disposal in the United States in the Supplement to tiie Health Physics Journal, Vol. 76, No. 5, May 1999. It is noted in tiiis article tiiat the volume of tiiis type of waste has decreased from 3.8 million in 1990 to 0.32 milhon in 1997. 

Math Survival Guide Tips and Tricks for Science Students, 2nd Edition, a paperback summary of basic skills with practice exercises in every chapter. Foundations of Chemistry in the Laboratory, 13th Edition, by Morris Hein, Judith N. Peisen and Robert L. Miner includes 28 experiments for a laboratory program that may accompany the lecture course. Featuring updated information on waste disposal and emphasizing safe laboratory procedures, the lab manual also includes study aids and exercises.

For those waste streams that can impact public health or the environment (if mismanaged), provide a summary of the treatment and disposal methods (for example, solvents are incinerated or recycled, lab wastes are incinerated) used to manage them and identify the on-site or off-site facilities used. Is the disposal of the waste adequately documented (for example, retention of manifests, bills of lading or transfer notes) ...

In summary, many studies have indicated the widespread formation of a variety of secondary phases in weathered CCB waste materials. Natural weathering processes therefore appear to play an important role in the sequestration of trace elements in ash disposal environments. Additional study is needed to identify and determine the chemical compositions of these secondary phases and to obtain pertinent thermodynamic, kinetic and adsorption data that can be used to model the mobility of trace elements in these complex weathering systems.
