Environmental Protection, Resource Allocation and CERCLA: A Practitioners Perspective
In accepting Superfund's mandate of protection of human health and the environment in a timely manner, critics often overlook, the limited human, technical and material resources...

The Effects of Hazardous Organic Pollutants on the Performance of Activated Sludge Systems
The effects of phthalate esters (diethyl phthalate and dimethyl phthalate) and phenols (2,4-dinitrophenol, 2,4-dimethylphenol and 4-nitrophenol) on the performance of a laboratory-scale...

Vacuum Anaerobic Treatment: A New Approach
Anaerobic processes have an organic loading limit that when exceeded leads to process failure. The research summarized in this paper demonstrates that both organic removal rate enhancement...

Optimization of Innovative Biological Treatment
This paper presents the experimental and theoretical development of a method for predicting the optimal operating conditions for an innovative biological reactor design. The innovative...

Trihalomethane Control: A Case Study
Controlling trihalomethanes (THMs) has been an important part of many utilities' water treatment programs since THMs were first regulated in 1979. The increased disinfection...

A Case Study in Sludge Handling
When the Wyoming Valley Sanitary Authority (WVSA) converted its operation to a secondary treatment plant in 1988, something important was missing. That something was a method to handle...

Microbiological Stabilization Through Aerobic Digestion and Storage
A study was conducted to evaluate the pathogen indicator bacterial reductions in the sludges of six wastewater treatment plants. These plants were extended aeration and oxidation ditch...

Chemical Sludge Treatment?A Way of the Future
Recently, chemical treatment of municipal sludges has become an alternative to incineration, composting, and digestion. The commercial processes have evolved into three categories of chemical...

Environmental Impacts of Drought in the Tennessee Valley
Beginning in June 1984, the Tennessee Valley region entered the most severe, extended period of drought since record keeping began in 1890. The historical annual average rainfall across...

The Mission of the Corps of Engineers, South Pacific Division, in Hazardous/Toxic Waste (HTW)
This paper discusses the various roles and relationships that the South Pacific Division has for HTW activities within the division's four-state area (CA, AZ, NV, and UT)....

California Standards for Characterizing Contamination and Assessing Risk from Hazardous Waste Sites
The Toxic Substances Control Program (TSCP) of the Department of Health Services is responsible for managing California's hazardous waste program. A primary goal of TSCP is...

The State Water Board's New Monitoring Requirements
In coordination with Department of Health Services' (DHS) efforts to gain 'State Authorization' to administer the federal hazardous waste management...

The Greening of Corporate America
Since the decade of the 80's has seen both the most stringent environment regulations as well as the most destructive environmental incidents in our history, most American...

Degradation of Ortochlorophenol in Aerobic and Anoxic-Aerobic Processes
Removal of OCP in sequencing batch reactors was shown to be independent of the presence or lack of co-substrate and independent of SRT for fully aerated reactors. The reactors with an...

Implementation of Agricultural Reuse in Florida
In mid 1986, the city of Sarasota was faced with the problem of removing a discharge of secondary treated wastewater from Sarasota Bay. The city embarked on a comprehensive evaluation...

High Level Radioactive Waste Management 1991
The proceedings of the second annual international conference on High Level Radioactive Waste Management, held on April 28 - May 3, 1991, Las Vegas, Nevada, provides information on the...

Pumped Storage Promise
With many utilities facing potential shortfalls in generating capacity, pumped storage hydro plants could be a key to meeting peak-period energy demand in the 1990s. Pumped storage plants...

A Case for Modernizing the Funding and Repayment of Regional Water/Power Projects
Several regional water/power projects authorized by Congress remain unfunded and therefore uncompleted year after year. In this paper examples of such uncompleted projects are examined....

A Demonstration of Strobe Lights to Repel Fish
An EPRI review (EPRI, 1986) of fish protection systems for hydroelectric facilities identified strobe lights as a potential behavioral system to minimize fish entrainment. In 1988, EPRI...

A Water Budget Approach to Instream Flow Maintenance
Storage reallocation is a current issue at many Federal water storage facilities that have hydroelectric generation. Allocation of storage to support instream flows is one of the changes...
