1. Even though there is still a microscopic amount of chemicals left in a completed blocked off area, how can you prove it's not in the air?
2. How do you plan to deal with the people who no longer want to live there due to the way it's effecting there family, but can't due to the economic crisis of today.
3. Are you going to fund medical needs for the people who have been or already were effected?
4. By a show of hands, how many people have not been effected in anyway, whether it be you or a family member or a friend, by the chemicals in the canal.
5. About how long does EPA estimate for the chemicals to biodegrade, if ever?

Catalyst 8/30
1.) What caused the toxic waste to begin being pushed to the surface?
The Blizzard of 1977 caused the "bathtub effect" on the canal. With all the winter snow, rain, etc. caused an early spring and an early thaw, and all the water was forced underneath the canal from this clay pit to the top and it started oozing out of the top of the canal.
2.) What are some of the health hazards associated with the chemicals dumped there?
There were over 400 chemicals found there. Including lead, arsenic, lindane, a variety of other pesticides, benzene, and many more. Many of these cause cancer, some of them cause liver problems, liver disease, many of them cause central nervous system problems and some of them cause birth defects.
3.) Besides humans how are other parts of the ecosystem affected by this?
The chemicals flowed to a nearby set of creeks. The chemicals had made there way underground to the creeks. The EPA wanted to dredge the creek.

Hazards of Oil Dispersants
Long term effects of dispersants the physical effects on marine life.
"74% of the oil had either been directly captured, burned or skimmed; evaporated at the surface; been consumed by micro-organisms; or dissolved or dispersed into microscopic droplets under the water... That left just 26% of the original spill still present, either in sheen or in weathered tarballs, on the shore or buried in sediment."
There is a lot of this "74% gone" inside the animals or on them! So technically it isn't gone, it's just "misplaced".

8th grade dlc reflection
three things i want to know about chemical dispersants are:
1. why isn't there a safer one, that isn't toxic
2. how does it effect the animals in a negative AND postive way, if any
3. how does effect humans and the environment
