Treatment of metal-laden hazardous wastes with advanced clean coal technology by-products. Quarterly report, May 1995--August 1995

Abstract

This fourth quarterly report describes work done during the fourth three-month period of the University of Pittsburgh`s project on the {open_quotes}Treatment of Metal-Laden Hazardous Wastes with Advanced Clean Coal Technology By-Products.{close_quote} Participating with the university on this project are Dravo Lime Company, Mill Service, Inc., and the Center for Hazardous Materials Research. This report describes the activities of the project team during the reporting period. The principal work has focussed upon the production of six sets of samples with high water content for solidification testing and the mixing of five dry samples for solidification testing by the Proctor method. Twenty-eight day compressive strengths are reported for five of the six sets of samples with high water content. The report also discusses completion of the format of the database and the inclusion in it of all data collected to date. Special reports presented during the quarter include the Continuation Application, a News Release, and modification to the Test Plan. Work is progressing on the NEPA report and the Topical Report. The activity on the project during the fourth quarter of Phase one, as presented in the following sections, has fallen into six major areas: (1) Completion of by-product evaluations, (2) Completion of analyses of six wastes, (3) Initiation of eleven solidification tests, (4) Continued extraction and extract analysis of solidified samples, (5) Development of the database, and (6) Production of reports.
