1.)What caused the toxic waste to begin being pushed to the surface?
Answer: The blizzard and heavy rain of 1977 filled the "bathtub" where the chemicals where. When the "bathtub" filled, a water chemical sludge oozed out and contaminated storm drains, wells, and even streams around the love canal area.
2.) What are some of the health hazards associated with the chemicals dumped there?
Answer: The problem with the Love Canal disaster is that nobody really knew what was dumped into the canal. Also, because the EPA had just started, there was very little knowledge on what these chemicals could do. All they really knew was that there was dioxin in the canal which could cause birth defects.
3.) Besides humans how are other parts of the ecosystem affected by this?
Answer: The parts of the ecosystem that where affected by this where, the underground animals like ground hogs or even the worms; the fish that swam in the contaminated streams; any animal that drank the contaminated water; and lastly, any animals that ate the smaller animals, like bears.
