Paths of Pollution: PCBs and the Great Lakes
As industries began to proliferate around the Great Lakes and its tributaries, contamination also began to accumulate in its waters. PCBs, which do not biodegrade, were routinely discharged into the environment before scientific evidence revealed th...
Paths of Pollution: Great Lakes: The Problem of Cross-Contamination
Areas that are not directly contaminated by industrial pollutants can be cross-contaminated through the migration of fish and water fowl. The Wold River is such a spot.
Paths of Pollution: Great Lakes: The Health Effects of PCBs
The population of the Great Lakes region continues to suffer the health affects of PCBs. It is a probable carcinogen, it can affect the immune system, cause IQ deficits and problems integrating socially, and reproductive abnormalities. Some believe ...
Paths of Pollution: Cleaning Up the Fox River
The potentially responsible parties for the discharge of PCBs into the Fox River-the companies along the Fox River-propose the natural attenuation method of remediation. EPA does not consider this natural burial of the contaminated sediments a perma...
Paths of Pollution: Great Lakes: Remediation Methods
The three main methods of remediation are hydraulic dredging, natural attenuation, and capping the contaminated sediments with a layer of clay or sand. Dredging is the preferred method because of its permanency. The contaminated sediments go through...
Paths of Pollution: Great Lakes: Remediation Efforts
Remediation efforts in the Great Lakes Basin are ongoing. Most of the industry is found along the rivers and tributaries, and the objective is to remediate the sediments before they are swept into the open lake. The goal is to get the most highly co...
