The chemical and physical methods to recycle or dispose of materials which, without treatment, are deemed to have no further value or are too contaminated to be used.
Research findings and examples of application to real problems--When can natural processes to reduce, or even destroy, contaminants at toxic waste sites be relied on?
Study of the effects on the Gulf of the Farallones National Marine Sanctuary resulting from the disposal of San Francisco dredged material and barrels of low-level radioactive waste with links to publications and atlas with digital images.
Research findings and examples of application to real problems--biosolids have high concentrations of household contaminants compared to treated liquid wastewater effluent.
Brief descriptions of research programs in water resources in Kentucky with a few links to program websites. Programs include data collection projects, acid mine drainage, hydrodynamics, geology, waste site cleanup and hydrogeology.
Webpage based on USGS Open File Report 98-139 links to information on the San Francisco Bay estuary to study dredge disposal effects, fish habitats, sediment transport, rock pinnacles and navigation, and consequences of a large oil spill.
The area contributing recharge to this aquifer is undergoing rapid growth, generating more wastewater. We found that nitrate, a major component of wastewater and a nutrient that can degrade water quality, has increased in the creeks in this area.
Reports concentration of organic compounds here, to serve as a baseline against which future measurements can be compared and to provide a general assessment of the quality of local water treatment efforts.
Overview of studies of marine sediment on the continental shelf south of Los Angeles contaminated with DDT and PCBs from past sewage effluent discharges with links to research on Santa Monica Bay, Los Angeles Shelf and Palos Verdes Peninsula.
