However, groundwater sources can become contaminated with germs, such as bacteria, viruses, and parasites, and chemicals, such as those used in fertilizers and pesticides. 1. This is followed by the “Exponential Phase” in which cells divide regularly by binary fission, and grow by geometric progression. When power plants create acid rain, the chemicals from this rain will eventually reach the groundwater, which makes the water unusable for drinking and irrigation. Most pathogens that can contaminate water supplies come from the feces of humans or animals. Many different disease-causing microorganisms— bacteria , viruses, and parasites—can taint foods and liquids, each potentially associated with a different illness.
