General Information regulations limiting the amount of certain contaminants in water provided by public water systems. The Food and Drug All drinking water, including bottled water, may reasonably be expected to contain at least small amounts ofs some contaminants. Administration regulations establish limits for contaminants in The presence of contaminants does not necessarily indicate that the bottled water that must provide the same protection for public Protection Agency's Safe Drinking Water Hotline (1-800-426-4791) Lead can cause serious health problems, especially for pregnant Some people may be more vulnerable to contaminants in drinking home plumbing.
