Municipal water, including bottled water, may reasonably be expected to contain at least small traces of certain contaminants. The presence of these substances doesn't necessarily indicate a health risk. Additional information about contaminants and potential health effects is available through the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline (800-426-4791).

Sources of tap water (both municipal and bottled) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels across land surfaces or through underground layers, it dissolves naturally-occurring minerals and, in some cases, radioactive materials, and can pick up substances resulting from animal or human activities:

• Microbial contaminants such as viruses and bacteria from sewage treatment facilities, septic systems, agricultural operations, and wildlife
• Inorganic contaminants like salts and metals occurring naturally or from urban runoff, wastewater discharges, oil/gas production, mining, or farming
• Pesticides and herbicides from agriculture, urban stormwater runoff, and residential usage
• Organic chemical contaminants, including synthetic and volatile compounds from industrial processes, petroleum production, gas stations, urban runoff, and septic systems
• Radioactive contaminants that occur naturally or result from oil/gas production and mining activities

To ensure tap water safety, EPA establishes regulations limiting contaminant levels in public water systems. FDA regulations set similar limits for bottled water to provide equivalent public health protection.
