Love Canal is like the tip of the iceberg... if you Google it, you will see stories of a spill or the past dumping, but nothing of what is already in the ground.
I am far from a conspiracy theorist, far, far from it, but there is a concerted effort to cover up the continued presence of underground chemicals to include dioxin and carbon tetrachloride.
One of these days, the chemicals will leak (if they have not already) into the ground water and/or the Niagara River, and suddenly people will get sick again like Love Canal and not know why.
Look how close the Niagara Falls Power Plant Extension and Visitors Center is to the Hooker Hyde Park Site full of dioxin, etc.
