River Valley Cancer Scare

I live in the northern part of Delaware county, about 20 minutes away from River Valley Schools in Marion, Ohio. Some of the schools in the district were built on top of land that the US Army had used as a waste site for various toxic chemicals. Medical officials in the area had noticed a spike in cancer rates, especially leukemia, among students. The Ohio EPA announced that a new high school, new middle school, and two new elementary schools were to be built else where. The cost for these new schools was just shy of 10 million dollars, all paid by the government. The new schools were completed in 2003 and clean up for the waste site began in 2004. I do not think that this has affected me personally, it has definitely affected the area around where I live. I do not know for a fact if wildlife has been hurt due to the waste, but if people were developing cancer, why would animals be excluded from this? The area in which this is taking place, has many many farms. Corn and bean fields are what make up most of this part of the county, so it is kind of scary to think that maybe the waste could be affecting the crops as well. If this is so, then it is no longer just the students of River Valley that are being effected, but now the entire surrounding community.
