Steve, I remember a study done by Harvard on chemical contamination in West Virginia's Kanawha Valley. Harvard finished their study, which was certified by the federal government, and
later disputed by Dr. Basudeb DasSarma of WV State. The government felt the study fit all the criteria they had set down. The problem was the study was done haphazardly, and multiple contaminants were misidentified by the experts sent to study them and their effects on the human population living nearby.
Dr. DasSarma made the folks from the government and Harvard look like idiots in short order over that study...
BTW, I helped Professor DasSarma set up his air quality testing stations on top of the WV State Chemistry building, which sits just downwind of the only plant left in the world which still manufactures the chemical that leaked at the Carbide plant in Bhopal, India, killing everyone for miles around the Bhopal plant (
MIC, or methyl iso-cyanate). That was just one of the chemicals the Harvard study misidentified. Professor DasSarma began testing the air quality, and idetifying chemical leakages from that plant, starting with his arrival in Institute, WV on the WV State campus. The Harvard folks thought a quick study, with the Harvard name behind it, would be enough to whitewash over the real facts. Professor DasSarma dissuaded them of that notion in short order...
So just because something fits the criteria, it doesn't mean it's correct...
