The correlation between cancer rates and chemical waste pollution is plausible. While superfund sites do seem to have an effect on the cancer rates within a population, there are more variables that factor into cancer that are more difficult to isolate at this time. For each superfund site, there’s a difference in the chemicals spilled and the length of time it went unnoticed. For each county, there’s a difference in the locations of superfund sites within the county. For cancer, there’s a difference in the type of cancer the recorded count has contracted that may be of a different cause. These and other variables are points that could not isolated at this time, that would be able to improve the quality of the resulting data. But with all these points of error considered, there is still a noticeable correlation between the cancer data and superfund sites that cannot be ignored.
