Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...

Potential Microbial Impacts on Groundwater Quality
Over the last decade there has been significant progress in the understanding of sub-surface microbiology. The ubiquity of microorganisms within groundwaters forms a major part of these...

Pilot Testing of a Zero-Discharge Treatment Process
As environmental regulations become more stringent, pulp and paper mills are investigating alternatives to conventional biological treatment and discharge of effluents into receiving waters....

Permeability of Clay Liners with Contaminants
Clays are increasingly used as liners for waste disposal facilities. Chemical compatibility studies with hydraulic conductivity tests must be performed to determine the effect of the waste...

Design and Implementation of a Multi-Faceted Site Remediation
This technical paper presents a case history of the design, construction, and start-up of a multi-faceted site remediation system. The case history includes a description of the site background,...

Risk Analysis of Drinking Water Treatment and Supply Facilities Handling Highly Hazardous Chemicals
Due to increasing public concern of risks from handling highly hazardous chemicals at various facilities, a number of state regulatory agencies, including the State of California, have...

Anaerobic Biodegradation of High Energetics in Digestion Sewage Sludge
The digested sewage sludge culture is highly effective for denitrification and the subsequent degradation of energetics contained nitrites. Two energetics, ADN (ammonium dinitramide) and...

Constructed Wetlands for Metals Removal
Constructed wetlands have the potential to trap and remove metals contained in wastewater. Long term removal is expected to occur by accumulation and burial in the plant detritus in a...

Hazardous Soil Remediation: A Cooperative Effort between Industry and Government
E. I. du Pont de Nemours and Company's Antioch Works (Dupont) is on the San Joaquin River 30 miles east of San Francisco, California. For about 25 years, ending in 1981, Dupont...

Health Risk Sensitivity to Variable and Uncertain Parameters
A methodology is presented that attempts to quantify the effects of individual variability and parameter uncertainty in a groundwater-driven health risk assessment. Two modeling approaches...

Regional Groundwater Management with Health Risk Assessment
A regional groundwater system may have several areas which are contaminated with organic chemicals. In general, the objective of groundwater management is to supply the demand for water...

The Environmental Valuation Reference Inventory (EVRI) for Water Related Benefits Transfers
Managing our water resources requires knowledge not only of flows, water chemistry and aquatic life, but also of the various uses and economic values that humans place upon the water....

Recover Inorganic Solids from Obsolete Propellants
A feasible process was developed to recover inorganic solids (energetics and metallic fuel) from obsolete polyurethane-based propellants in order to solve their associated long-term disposal...

Specification of Cu, Pb and Cr in Contaminated Sediment Effected by pH
Sediment was sampled from a contaminated river. Sequential extraction was applied to determine the speciations of Cu, Pb, and Cr in the sediment with varied pH (5–9), and the redox potential...
