BACTERIA. Some bacteria do cause disease such as Cholera, Tuberculosis, and Legionnaires disease. Most bacterial species can be opportunistic pathogens and these can be treated with antibiotics. The most common bacterial infections are caused by Staphylococcus aureus. Bacteria indicators of sewage contamination consist of E. coli, Enterococcus, and total Coliform. Legionella is an aerobic, Gram-negative, rod-shaped bacterium genus. It includes species that cause the disease legionellosis. Two forms of legionellosis are known as Legionnaires' disease and Pontiac fever. Legionella bacteria are found in water sources within the environment and can exist as facultative (optional) parasites. When parasitic, their host is a protozoan in the Kingdom Protista, i.e. amoebae. Legionella grows best in warm, stagnant water, like the kind found in hot tubs, cooling towers, hot water tanks, large plumbing systems or air conditioning systems in large buildings. Generally, Legionella is associated with poorly maintained cooling towers, potable water systems or a warm water system that disseminates water particularly as aerosols, sprays or mists. The EPA sets a maximum contaminant level goal (MCLG). The MCLG is the maximum level of a contaminant in drinking water at which no known or anticipated adverse effect on the health of persons would occur, allowing an adequate margin of safety.
LEAD. EPA and the Centers for Disease Control and Prevention (CDC) agree that there is no known safe level of lead in a child's blood. Lead is harmful to health, especially for children. Lead can enter drinking water when service pipes that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The most common problem is with brass or chrome-plated brass faucets and fixtures with lead solder, from which significant amounts of lead can enter into the water, especially hot water. Homes built before 1986 are more likely to have lead pipes, fixtures and solder. The Safe Drinking Water Act (SDWA) has reduced the maximum allowable lead content -- that is, content that is considered "lead-free" -- to be a weighted average of 0.25 percent calculated across the wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures and 0.2 percent for solder and flux.
