Making Decisions about Hazardous Waste Remediation When Even Considering a Remediation Technology Is Controversial

Hazardous Waste Site Remediation, Neighborhood Change, and Neighborhood Quality.

We tested the hypothesis that neighborhoods with hazardous waste sites may no longer be undesirable places to live if they have been at least partly remediated. We collected 377 questionnaires (42% response rate) administered from within one-half mile of the number 1, 4, and 12 hazardous waste sites on the National Priority List (Superfund). These neighborhoods were rated higher quality than ne...

Innovative Methods for the Assessment of Hazardous Waste on Remediation

The hazardous waste remediation process is completed through multiple phases each served by differing professions. First, geologists, hydrogeologists, the EPA and consultants complete a site assessment and investigation at a potential hazardous waste site. The environmental engineering and consulting professionals are then responsible for providing design services. Finally, construction profess...

Site Remediation Using Soil Mixing Techniques on a Hazardous Waste Site: a Case History

Petroleum hydrocarbons had affected site soils at three separate locations over the estimated area of approximately 32,000 sq. ft. The depth of contamination varied from 3 feet in two areas to over 20 ft. in the area next to the retaining wall. Total Petroleum Hydrocarbon (TPH) concentrations ranged from less than 50 ppm up to 11,000 ppm with levels varying from the surface to the groundwater t...

Enzyme technology and biological remediation

The heterogeneous complexity of sludges and wastewaters has created gross uncertainty and deviations in predictions of suitable models for their measurement. At the same time, it is becoming increasingly obvious that the current paradigms and ideologies are wrought with problems and limitations suggesting the need to move to a more consolidated analytical objective evaluation. Rapid development...
