Pre-Spill Planning for Natural Resource Damage Assessments
The effectiveness of the natural resource damage assessment (NRDA) process for oil and chemical spills can be improved by planning and coordination among natural resource trustees before...
Water Quality Impacts of a Lead/Zinc Mine in Northwest Alaska
In order to assure that water quality in the Red Dog Creek/lkalukrok Creek/Wulik River watershed returned to pre-mining conditions, the order required that water quality and fish tissue...
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...
Bioaccumulation in Mussels Caged in Alamitos Bay, CA
Alamitos Bay is a coastal embayment located in the southern portion of the highly urbanized Los Angeles basin. There is concern of the potential for contamination stemming from urban non-point...
The NS&T National Benthic Surveillance Project: Contaminants in Fish Tissues
The National Benthic Surveillance Project, part of NOAA's National Status and Trends (NS&T) Program, has been regularly measuring more than 70 contaminants in liver tissue of selected...
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...
Environmental Impacts of Human Activities on the Coastal Areas of Nigeria
Nigeria has a coastline of approximately 800 km and the coastal areas support a myriad of economic activities as well as a large population. This paper reviews the geology, geomorphology,...
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....
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
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...
