Waukegan, Illinois and the Outboard Marine Corporation From the 1940s until the mid 1970s, the Outboard Marine Corporation was the economic heart and soul of a bustling northern suburb town of Waukegan. Employing more than 5,000 workers at its peak and O. M. C was unchallenged in the community and O. M. C was allowed to do whatever they wanted as long as they continue to bring in prosperity to Waukegan. What they were allowed to do was dump millions of gallons to toxic sludge into lake Michigan, sludge containing Polychlorinated Biphenyl (PCB), Arsenic, Polycylic Aromatic Hydrocarbons, Ammonia, Benzene and Trichloroethylene toxins.
Waukegan Harbor became the Chenobol of the Midwest when this appaling act of polluting was discovered in the 1970s. Waukegan, a city that sits north of Chicago, Chicago, a city that depends on lake Michigan for drinking water, for over 20 years millions of people where exposed to these toxins from the act of one corporation. Arsenic, PCB has been associated with causing skin, breast, bladder, lung and kidney disease, Hydrocarbons can cause lung, skin, leukemia, breast, throat and larynx cancers.
The Environmental Protection Agency declared in 1993 that the site was mostly cleaned, mostly because the site still contained contaminated deep underwater deposits of toxins and by this time all the clean up was funded by taxpayers, The United State E. P. A Superfund. O. M. C closed their doors for good in the year 2000, the huge plant sitting on a 1,000 acres is still consider highly toxic, but the E. P. A stated that there is no public health hazard because access to the site is limited.
The city of Waukegan’s original plans was to transform the site into a recreational area, native habitat but with the city being a economic former shell of what it once was, it would highly benefit by transforming that land into residential, which would bring millions in tax revenue to a struggling economic depressed city of Waukegan. The problem with transforming the site into residential would be a mass clean up that would cost in the millions of taxpayers dollars. The site would have to be mechanically dredged, drained, top soil transferred to landfills.
A process that add’s pollutants, to an already fragile area. The solution, simple the horticultural application of Phytoremediation, which is essential using plants as natural vaccums to suck up deadly toxins from the soil and rendering the toxins, harmless. Plants that are known as Hyperaccumulants. Not every plant is considered a polluntant vaccum, Hyperaccummulants are selected for their natural abilities to combat deadly toxins and unfortunately their list so far are quite small.
Because of this a majority of the plants, trees, shrubs that are used are non-native species. So they are carefully monitored and checked so they do not become an invasive species. Trees such as the willow and popular remove heavy metals from the soil, the Wild Lupine Lupinus Albus removes arsenic and Buffalo Grass Buchloe Dactyloides is a perennial grass that removes hydrocarbons and the deep rooted perennial herb the White Clover Trifolium Repens removes hydrocarbons and PCBs.
Phytoremediation is a cost effective approach and since the plants transfers the toxins from their roots to their steams and leaves, the steams and leaves can be collected and destroyed while leaving the plants root system intact to continue leaching out the toxins. They degrade and sometimes even eliminate the toxins, they are less harmful to the environment than the mechanical methods so why not use this method
