example occurred Woburn Massachusetts for about 10 years where many children unfortunately contracted leukemia. Other than Leukemia, residents of Woburn Massachusetts, when the contamination was at its worst, also show signs of liver, kidney, prostate and urinary track cancer. Risks of congenital abnormalities and birth defects were also present during that time(all about water filters). The last example was more recently in 2012 in Mutare, Zimbabwe, where where in a village somewhat nearby from the polluted water in Mutare caused children to gain horrible rashes that covered their entire bodies just from exposure to the contaminated water. These were horrible accidents that only took a little bit of tampering of the water source to cause epidemics
