The research objectives were definition of trihalomethane formation potential (THMFP) reduction in groundwater matrix using ultraviolet radiation (UV) catalyzed ozone oxidation (UV/Ozone)....
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,...
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...
C.t. Disinfection Practices in Open Chlorine Contact Basins
Susequent to an increased incidence of giadiasis in the coomunity in 1982 it became evident that Westpac had to improve its disinfection process and its ability to determine their effectiveness....
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...
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...
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...
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...
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...
