Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....
Navy Targets Effective Infiltration/Inflow Elimination
The Naval Facilities Engineering Command (NAVFAC), Chesapeake Division, retained the services of RJN Environmental Associates, Inc. to perform a Sanitary Sewer Evaluation Survey (SSES)....
Toxicity Bioassay Using Nitrifying Bacteria
Monitoring water quality by the use of toxicity bioassay was studied with respect to the interrelationship between nitrifying activities, ammonium and inorganic compounds. Differential...
Screening Level Modeling in Support of an Estuarine Toxics Management Program
Mathematical models will be used in the future to determine maximum allowable pollutant loading rates for several toxics to the South San Francisco Bay Estuary. This project consisted...
Evaluation of
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...
Remedial Planning for the Former EXPO 86 Site
This paper describes the site characterization and remedial action planning effort that is being undertaken at the former EXPO 86 site in downtown Vancouver, B.C. The 200 acre site on...
An Engineered Reactor Approach to Integrating Physicochemical and Biological Processes for In-Situ Bioremediation of Contaminated Subsurface Systems
The concept of integrating biologically active granular carbon reactors into groundwater recycle schemes to provide continuous acclimation and enrichment of microorganisms and inoculation...
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...
Salinity Problems Associated with Reuse Water Irrigation on Southwestern Golf Courses
One of the most severe of the potential reuse water quality problems is salinity. While many water supplies in the southwest have relatively high total dissolved solids (TDS) concentrations,...
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...
Assessment of Effects of a Water Supply Withdrawal on Downstream Flows for Anadromous Fish Reproduction
A BASIC computer model was developed to simulate reservoir operations in conjunction with a proposed water supply withdrawal. The model was used to assess the potential impacts of the...
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...
Redevelopment of Remediated Superfund Sites: Problems with Current Approaches in Providing Long-Term Public Health Protection
The normal primary objective of Superfund site remediation is the control of hazardous chemicals so that they do not represent a significant threat to public health and the environment...
Tracer Study for C*t Compliance Evaluation
A tracer study was performed with a fluorescent dye, Rhodamine WT, to determine the actual disinfectant contact time for the 36-mgd Courtney Bend Water Treatment Plant near Independence,...
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....
