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...
The Direction of the Point Source Program
The NPDES permit programs operate under the concept of providing for a cleaner environment by restricting the release of pollutants. Over 500,000 sources are now subject to regulation...
GIS Applications in Modern Stormwater Management
A Geographic Information System (GIS) is a technology that aids stormwater management through efficient data manipulation, analyses, and graphic displays. The integration of GIS with stormwater...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
A Decision Making Approach for Stormwater Management Measures?A Case Example in the City of Waukesha, Wisconsin
An urban nonpoint source pollution predictive model (Source Load and Management Model?SLAMM; Wisconsin Department of Natural Resources, 1990), and a decision matrix developed specifically...
Calibration of a Water Quality Model Using the Influence Coefficient Algorithm
A methodology based on the influence coefficient algorithm was established for the calibration of QUAL2E reaction coefficients. It was applied to the stream sections of the South Han River...
The Mamala Bay Study, Oahu, Hawaii: Introduction
A comprehensive multi-disciplinary study was conducted to evaluate the effects of point and non-point source discharges on the water quality of Mamala Bay, Oahu, Hawaii. The investigation...
Lake/Reservoir Restoration Activities in Taiwan
The paper presents a brief overview of recent lake and reservoir restoration project activities in Taiwan, an island nation in a sub-tropical and relatively wet climate. Because of steep...
Hollyhills Drain Relief for 1920s Drainage System
The paper will discuss design and construction problems encountered for a $50,000,000 Urban Storm Drain System in the Metropolitan Los Angeles Area. The Drainage System relieves a system...
Pollution Transport in Karst
A new model of pollution transport in natural streams was developed and tested. Dead zone storage is modeled as a two time constant process. This approach better matches the observed persistence...
Seawater Intrusion Solutions for the Salinas Valley
Seawater intrusion has been occurring in the aquifers of the Salinas Valley ground water basin for more than 40 years. Two capital projects that will help reduce the rate of seawater intrusion...
Brownfields Boom
A brownfield is a leftover, unused industrial land parcel thought to have a prohibitively expensive clean-up required before developing. For years brownfields were battlefields for litigation...
When Toxics Meet Metal
