Tap water, including bottled varieties, may contain small amounts of various contaminants. The presence of these substances doesn't necessarily indicate a health risk. For detailed information about contaminants and potential health effects, contact the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline (800-426-4791).

Water sources include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water moves over land or underground, it dissolves natural minerals and sometimes radioactive material, and can pick up substances from animal or human activities:

• Microbial contaminants from sewage treatment facilities, septic systems, agricultural operations, and wildlife
• Inorganic contaminants like salts and metals, occurring naturally or from urban runoff, industrial discharge, oil/gas production, mining, or farming
• Pesticides and herbicides from agriculture, urban 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

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.
