Case Studies of Ocean Outfall Inspections?San Francisco and Seattle
Discharge of effluent from municipal wastewater treatment plants via outfalls into the nearshore ocean environment is a common means for disposal of waste and street water runoff coastal...
Upper Watershed Management and Sedimentation in Mugu Lagoon, Ventura County, California
Mugu Lagoon is one of the last remaining, natural salt marsh systems in southern California. In the last 90 years, sedimentation in the lagoon has increased from a geologic rate of 0.17...
Nutrients in the Gulf of Mexico
Excess nutrients in the Gulf of Mexico are related to at least three important environmental problems: episodic oxygen depletion, sea grass decline, and shifts in composition of biological...
Potential for the Bioremediation of Contaminated Dredge Material
Sediment contamination frequently impacts the ability of ports to maintain and deepen shipping channels. One of the common contaminants in channel sediments is polycyclic aromatic hydrocarbons...
Ecological Situation of the Black Sea Coastal Zone
Some aspects of the Black Sea ecosystems evolution are discussed with regard of growing volumes of discharged pollutants and encroachment of Mnemopsisleidyi. The data characterizing ecological...
Boston Harbor Management: Issues, Structure, and Directions
Alarming reports of massive pollution, highly publicized legal challenges and even Presidential political campaign accusations, all helped earn Boston Harbor a world wide reputation during...
Hydrology of Wetland Treatment Systems in East Orange County, Florida
Wetlands are increasingly being used as final treatment systems for industrial and domestic wastewater effluent discharges and stormwater runoff discharges. Hydrological monitoring and...
Establishment of a Habitat Monitoring Program to Assess Potential Impacts of Diversion of POTW Effluent
As part of the permitting process for a gas-fired power plant, the environmental impacts of diverting POTW effluent from the receiving water for cooling tower makeup was investigated....
Urban Nonpoint Pollution Control Kettering Demonstration Project
The development of effective nonpoint pollution control programs has become one of the most complex challenges facing local and state authorities. Because of the multifarious nature of...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
A Lake Water Quality Management Model to Evaluate Stormwater Management
A research project was completed to develop a dynamic lake water quality management model for Lake Tarpon, a 10.3 km2, shallow lake in Central Florida....
Combined Sewer Overflow Abatement by Means of Detention Basins and Stormwater Infiltration
The conventional approach to abate the pollution loads from combined sewer overflows (CSO's) is to include detention basins. The same reduction in CSO loads may be obtained by infiltrating/percolating...
Performance of Stormwater Ponds and Wetland Systems
The use of stormwater pond and wetland systems to improve the quality of urban stormwater runoff has become an increasingly important strategy to protect streams in developing areas. This...
A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...
Anisotropic Effects on Flow from a Recirculation Well
We examined flow in an unconfined aquifer near a recirculation well, which consists of a source and a sink of equal strength, with emphasis on understanding the effects of anisotropy....
In-Situ Bioremediation Using a Recirculation Well
An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use...
Petrochemical Facility Stormwater Management?A Case Study
As an integral part of a study to develop a combined wastewater treatment system for petrochemical facilities, comprehensive hydrological studies were performed prior to the detailed design...
Verification Tests for Transport Modeling in Coastal Aquifers
The U.S. Geological Survey three dimensional Heat and Solute Transport (HST3D) model is used to simulate fate and transport of dissolved contaminant in coastal aquifers. The model originally...
Urban and Agricultural Competition for Water, and Water Reuse
Competition for water can be resolved by construction of more facilities for storing water (dams, groundwater recharge) in wet years for use in dry years, by weather modification, watershed...
Wastewater Treatment and Disposal System for a Vegetable Processing Facility
The authors describe the implementation of a wastewater management system designed to dispose of up to 2.1 million gallons of vegetable processing wastewater generated per day at Bellingham...
