Beneficial Use of Waste Materials: State of the Practice 2012 (PUBLISHED REPORT)
Solid wastes produced in today’s society originate from a myriad of sources, including households, government, businesses, and industry. Current U.S. federal regulations for solid waste management have been developed to promote sound management of these wastes in a manner protect...
Patterns and sources of nitrogen and microbial contamination in a Pacific Northwest estuarine watershed (PRESENTATION)
Tillamook Bay, a National Estuary Program site, is located on the northwest coast of Oregon. The Bay is one of Oregon’s leading producers of shellfish for human consumption. However, high levels of fecal indicator bacteria that exceed state water quality standards often r...
Secondary Aluminum Processing Waste: Baghouse Dust Characterization and Reactivity (PUBLISHED REPORT)
Results presented in this document are of particular importance when trying to understand concerns associated with the disposal of BHD in MSW landfills. The MSW decomposition process is exothermic, creating landfill temperatures that are typically greater than 37° C with the pos...
Proximity of Private Domestic Wells to Underground Storage Tanks in Oklahoma (PUBLISHED REPORT)
For protecting drinking water supplies, the locations of areas with reliance on private domestic wells (hereafter referred to as “wells”) and their relationship to contaminant sources need to be determined. A key resource in the U.S. was the 1990 Census where the sour...
Materials Management: State of the Practice 2012 (PUBLISHED REPORT)
The report presents an evaluation of six materials management technologies that were assessed with respect to each technology's process, material and energy pathways, commercialization status, and associated economics. The inclusion and implementation of a materials recycling pr...
Locations with High Reliance on Private Wells: Not Always Where You Think They Are (PRESENTATION)
For developing contaminant management strategies and protecting drinking water supplies, the locations of areas with reliance on private domestic wells (PDWs) and their relationship to contaminant sources need to be determined. From 1960 to 1990, a key resource in determining are...
Marginal abatement cost curve for NOx incorporating controls, renewable electricity, energy efficiency and fuel switching (JOURNAL)
A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs typically are developed by sorting end-of-pipe controls by their rela...
