Growth in technology enhances need and utilization of electronic and electrical equipment’s (EEE) everywhere in the world. As a result, e-waste acquires a large share in the conventional solid waste stream. Limited recycling solutions available pushes the need for e-waste disposal solutions. The paper highlights the increasing e-waste pie in solid waste. Various disposal solutions available for...

3333679 37 6 $ E The Effect of Kiln Temperature on DRE and Organics Concentrations in Incinerator Ash W. R. Schofield, PhD, PE; W. V. Walls, PE; and Thomas Jones Chemical Waste Management, Inc. (CWM) conducted RCRA and TSCA trial burns on the world-scale hazardous incinerator a t Port Arthur, Texas, in early 1990. Subsequent commercial operation revealed start-up problems which included (1) com...

Significant progress was made during the past year to develop a sensitive, real-time continuous emissions monitor for accurately measuring a variety of hazardous (Resource Conservation and Recovery Act, RCRA) metals which can be present in the off-gas or stack gas of a thermal treatment process. The current work has focused on six metals: arsenic, beryllium, cadmium, chromium, lead, and mercury...

The EPA Regional Ground Water Forum is a group of EPA scientists representing Regional Superfund and Resource Conservation and Recovery Act Offices (RCRA). The Forum is focused on exchanging information related to ground-water characterization, monitoring, and remediation. The application of monitored natural attenuation (MNA) for inorganic contaminants in ground water is a topic of concern to ...

Volatile organic compounds (VOC) are present at over two-thirds of Superfund, Resource Conservation and Recovery Act of 1976 (RCRA), and U.S. Department of Defense sites (EPA 1996). Thus, remediation of VOCs is a top concern to the Environmental Protection Agency. Trichloroethylene (TCE) is a persistent VOC contaminant that infiltrates soil and ground water from improper disposal of dry cleanin...

During recent environmental laboratory audits conducted by the USACE, certain ‘questionable practices’ have been observed, especially in the organic analysis areas. Most people have a relatively good idea of what constitutes a fraudulent activity today. The concepts of ‘dry-labing,’ ‘peak shaving,’ ‘peak enhancing,’ or ‘time-traveling’ are well understood. These practices clearly involve the de...
