Small Inocula Can Effect In Situ Biodegradation
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...

Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...

An Experimental Study on the Use of Constructed Wetlands for Stormwater Management
The purpose of this study is to compare the pollutant removal effectiveness of selected wetland vegetation such as cattails, reeds, and bulrushes by using laboratory bucket wetlands. Pollutants...

Preparation of Notification Models Using Continuous Modeling Techniques
Public health departments in many states now require that operators of collection systems notify them of discharges from combined sewer systems soon after these events occur. This allows...

Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...

CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....

COASTMAP: An Integrated System for Environmental Monitoring, Modeling and Management
The development of COASTMAP, an integrated system for environmental monitoring, modeling and management for fresh and marine waters, is presented. The system allows the user to collect,...

Assessment of the Surface-Water Pollution and Measures for Emergency Stations Warning in the Republic of Uzbekistan
In the Republic of Uzbekistan, a special system operates that is designed for the observations on the quality and ecological state of the river ecosystems including: 1-hydrochemical control...

Experiences in Cleaning Up the Influence of Oil Spill on the Water Bodies
Experiences in cleaning up the influence of oil spill on water bodies of Komi Republic (European part of Russian North) and Dagestan Republic (North Caucasus) was generalized. In both...

Bacterial and Chemical Pollution of Littoral Waters of Lake Ohrid at Pogradec?Town Area
The Pogradec shore waters exceed these bacteriological standards and provide risks to the public health. The levels of the chemical indexes clearly show the influence of organic pollution....

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...

Development of Remediation Technologies Simulators
This paper summarizes on.going efforts to develop software for simulating various in situ, subsurface remediation technologies to improve remediation selection, design, and operation....

The DOD Groundwater Modeling System: A Conceptual Model Approach
A suite of new simulation tools have been developed in the version 2.0 of the Department of Defense Groundwater Modeling System (GMS). These add considerable complexity to the GMS which...

Storm Water General Industrial Permit Non-Filers Identification and Outreach
Storm water discharges convey pollutants from urban activities that can impair surface water quality. Industrial facilities have been identified as one source of storm water pollutants...

A California Handbook for Developing an Industrial/Commercial Storm Water Inspection Program
Runoff and non-storm water discharges to storm drains from industrial and commercial businesses can be major causes of storm water pollution in urban areas, but there are sources of this...

Water Quality Impacts of Dredging and Disposal Operations in Boston Harbor
The Massachusetts Port Authority is presently planning a navigation improvement project in the port of Boston, consisting of dredging the 10.7 m (35 ft) deep channels and berths in the...

Best Management Practices and Community Education
The 1987 Water Quality Act requires the permitting of municipal separate storm sewer systems and the reduction by permittees of the discharge of pollutants in stormwater to the maximum...

Management of Stream-Aquifer Systems in the 21st Century
Many water agencies, especially those in the arid and semi-arid southwest of United States rely on stream-aquifer systems for a significant proportion of their water supplies. Wastewater...

Comparison of General vs. Multi Sector NPDES Storm Water Permits
In November 1990, in response to the 1987 amendments to the Clean Water Act, the EPA initiated the National Pollutant Discharge Elimination System (NPDES) storm water permitting program....
