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....
The Standley Lake Protection Project
Until recently, there has been no physical separation between potentially contaminated runoff from the former Rocky Flats Nuclear Weapons Plant and Standley Lake, the nearby water supply...
A Practical Approach to Watershed Sanitary Surveys
A step-by-step approach for conducting watershed sanitary surveys can be successfully applied to watersheds of all sizes. The approach involves preparing a watershed map, contacting regulatory...
Controlling the Impacts of Development on Storm Water Quality through Proper Site Planning and Design
Land development and construction activities can significantly alter drainage patterns, increase runoff peak flow and volume, and contribute pollutants to storm water runoff. Federal and...
Water Quality Mitigation for the San Joaquin Hills Transportation Corridor
The San Joaquin Hills Transportation Corridor (SJHTC) is a 24 km Design/Build tollway which has been financed with bonds to be paid back with toll revenue. The Environmental Impact Statement...
Immobilization of Metals and Solids Transported in Urban Pavement Runoff
Urban areas in North America continue to grow in size and population. With this growth is an increase in automotive traffic, roadway pavement and deleterious anthropogenic constituents....
Development of Islandwide Groundwater Pollution Potential for Taiwan
Using the modified DRASTIC and existing and newly surveyed data, groundwater pollution potentials for all 10 groundwater basins in Taiwan were calculated on 2 km by 2 km grids. This paper...
Influence of Flooding Events on Suspended Matter Quality of the Meuse River (The Netherlands)
Flooding events of the Rhine and Meuse Rivers have struck The Netherlands in 1993 and 1995. In the Meuse River basin, the river forelands have been widely used for housing and agro-industrial...
River Dnister Pollution with Toxic Waste as a Result of Accident at Potassium Fertilizers Factory
River Dnister has a length of 1,352 km. Its spring is situated in Carpathian Mountains at the height of more than 900 m. Dnister runs across the territory of Ukraine and Moldova Republic...
