Clean drinking water is essential for good health, but water can sometimes contain microbial contaminants—microscopic organisms capable of causing illness. These contaminants include bacteria, viruses, protozoa, and other microorganisms. Microbial contamination is particularly important because even relatively small amounts of some disease-causing organisms can create a health risk. EPA states that for microbial contaminants that […]

Bacteria and Viruses in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Bacteria and viruses are among the most important biological contaminants that can affect drinking water. Unlike many chemical contaminants, microorganisms can multiply or spread rapidly and may cause illness after relatively short-term exposure. Potential sources include human and animal waste, sewage, agricultural runoff, failing septic systems, flooding, contaminated groundwater, and problems within water distribution systems. […]
