GENERAL INFORMATION
Copper is a metal found in natural deposits such as ores containing other elements. Copper is widely used in household plumbing materials. The major sources of copper in drinking water are corrosion of household plumbing systems; and erosion of natural deposits.
HEALTH EFFECTS
Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson's disease should consult their personal doctor.
MCLG ADVISORY - ACTION IS HIGHLY RECOMMENDED
Copper levels were detected in your water sample to exceed the maximum contaminant level goal (MCLG) or action level (AL). MCLG's are non-enforceable goals based on the possible risk and exposure over a lifetime with an adequate margin of safety.
ACTION IS OPTIONAL
Copper levels were detected in your water sample but do not exceed the maximum contaminant level goal (MCLG) or action level (AL). MCLG's are non-enforceable goals based on the possible risk and exposure over a lifetime with an adequate margin of safety.
