Lake Onondaga (US) is so polluted it was designated a hazardous waste site by the US Environmental Protection Agency. Phosphorous, ammonia, nitrite, mercury, bacterial contaminants, from a long history of industrial activity in the area, along with non-point source pollutants, combine to make this lake one toxic soup.
