Reuse of an Industrial Wastewater at Saturn
The cooling tower at General Motor's Saturn Plant in Spring Hill, Tennessee will produce blowdown wastewater at rates as high as 500,000 gallons (1893 m3/day)....
Nonpotable Reuse: Development of Water Quality Criteria for Shower Water Recycle
Shower wastewaters at a military installation have been characterized in terms of physical, chemical and microbiological parameters. Two treatment technologies, microfiltration and coagulation...
Adsorption of Lindane onto Whole Soil and Soil Organic Fractions
The work presented here investigated interactions of the subject pesticide with whole soil and select soil organic fractions and evaluated the commonly applied assumptions that adsorption...
Managing Water Treatment Residuals
The ASCE Task Committee on Water Treatment Plant Residuals conducted an informal survey of state and federal agencies to collect data regarding the regulation of drinking water treatment...
Impact of Proposed Radon Drinking Water Regulations on Groundwater Systems in California
This summer, the Environmental Protection Agency is expected to propose a maximum contaminant level (MCL) of 300 pCi/l for radon in drinking water. This anticipated MCL, if adopted, will...
Results of the Engineering Special Studies for the UMTRA Project?FY90
The proposed U.S. Environmental Protection Agency (EPA) groundwater standards (40 CFR 192) require that Uranium Mill Tailings Remedial Action (UMTRA) Project remedial action designs meet...
Modeling Analysis of CSO Impacts in a Tidal Basin
Short duration intensive inflows of combined sewer overflows (CSO) to marine tidal basins create stratified water quality for limited periods of time. Accurate assessment of water quality...
Using Multiple Water Quality Models for Determining Variable Emission Levels for Wasteload Allocation
We present a methodology for determining the least-cost wasteload allocations from multiple point sources discharging into a single water body. The system of point sources is modeled as...
An Analysis of Modeling Techniques in Pollution Management of Natural Water Systems
This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study...
Noise Control Program for the Boston Harbor Project
A noise control engineering program has been instituted for the Boston Harbor project to make the facility virtually inaudible at the property line. The program integrates the noise mitigation...
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...
A Water Availability Index for Reservoir Management
This paper extends tha Water Availability Index concept to downstream reservoirs in the Apalachicola-Chattahochee-Flint (ACF) system. This extended index should be helpful in adjusting...
Water Conservation Programs Impacts on Secondary Wastewater Treatment Performance
This paper presents summary details of a 1990 technical evaluation of the impacts of water conservation on the performance of several hypothetical secondary wastewater treatment plants....
Allocating Water Among Urban Users During Droughts
Beginning in the spring of 1987, California has been besieged by a drought that, as of this writing, has not yet abated. In response to this unprecedented drought, the San Francisco Water...
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)....
Ground Water Treatment System Using UV/H2O2 at Sacramento Army Depot
Ground water beneath the Sacramento Army Depot (SAAD) is being extracted and treated as part of a ground water remediation program. The extraction system is achieving contaminant capture...
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...
Role of Soil-Aquifer Treatment in Water Reuse
Reuse of municipal wastewater requires treatment so that the water meets the quality requirements for the intended use. Irrigation of vegetables consumed raw requires absence of pathogenic...
Plume Management for Groundwater Remediation
Site-specific data for four sites were compiled to evaluate the effectiveness of pumping and treating contaminated groundwater and recharging the treated groundwater to the surficial aquifer....
