Zinc
Naturally occurring metal and an essential nutrient for human health
EPA MCLG Level
2 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Zinc is an essential nutrient for human health, however, ingesting zinc above the recommended dietary allowance can have adverse health effects. Excess zinc exposure from drinking water is rare, but studies of excess oral intake of zinc show that it decreases the body's absorption of copper, leading to health effects induced by copper deficiency including anemia and impaired immune responses.
Affected Organs & Systems:
Common Sources
- Occurs naturally in rocks and soil
- Released into the environment as the result of waste streams from mining, smelting of zinc, lead and cadmium ores, steel production, and coal burning
- Zinc used in pipes and fittings can be released into tap water under corrosive conditions
How to Remove It
Water filters certified under the following NSF standards are effective at removing Zinc:
EPA MCLG Level
The EPA MCLG represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Zinc is classified as a Metals contaminant.
This contaminant primarily affects the immune-system, blood.
