Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...

The Binding Chemistry and Leaching Mechanisms of Zinc-Bearing Sludges in Cementitious Solidification/Stabilization Systems

Diffusion Model of Cu and Zn in Shallow Reservoir

Retention of Multiple Heavy Metal Ions by Fly Ash
Clayey soils are widely used as liner materials in landfills. They, not only retard the transport of leachates due to their low permeability, but also retain the heavy metal ions due to...

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...

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....

Protective Coatings -- Current Practices

Temporal Trends of Chemical Contamination at NS&T Sites
Recent temporal trends in concentrations of ten trace elements (Ag, As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn) and of five groups of organic compounds (butyltins, tDDT, tCdande, tPCB, and...

Safeguarding Steel
U.S. bridges are caught in the money squeeze. Painting has become a luxury few public agencies can afford and complying with EPA regulations has escalated costs even more. The paint/coatings...

A Baseline Study of Trace Metals in Marine Organisms from Ghana, West Africa
As part of the Joint FAO/IOC/WHO/IAEA/UNEP Project on monitoring of pollution in the marine environment of the West and Central African region, 279 samples representing 17 families and...

Physical-Chemical Evaluation of Rainwater as an Indicator of Atmospheric Pollution in Some Zones of the City of Maracaibo, Venezuela
This study provided an evaluation of the presence of pollutants in the air over the City of Maracaibo by means of a physical-chemical analysis of rainwater collected in four zones of the...

Decreased Fluxes of Pb, Cu and Zn from Elliott Bay

Behavior of Total Zinc in the Similkameen River
Multiple linear regression analysis was used to: develop equations that summarize the relationship between total zinc and a set of water quality characteristics measured in the Similkameen...

Estimation of Urban Stormwater Quality
Two data-based methods for estimating urban stormwater quality have recently been made available - a planning level method developed by the U.S. Environmental Protection Agency (EPA),...

Recyclying of Dust from Electric Arc Funances—An Experimental Evaluation
Each year the electric arc steelmaking industry generates approximately 650,000 tons of dusts containing valuable metallic resources such as iron, zinc, lead, and chromium. EAF dust is...
