Copper
Naturally occurring metal that is widely used in plumbing, faucets, and fixtures
Health Guideline Level (HGL)
0.3 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
Health protective levels of copper in drinking water have been established based on potential adverse effects to the gastrointestinal system, kidneys, and liver, especially for infants and children. Acute exposure to high copper levels uncommonly found in drinking water can cause nausea, vomiting, diarrhea, and stomach cramps.
Affected Organs & Systems:
Common Sources
- Most copper in drinking water comes from household plumbing
- Corrosive water, which usually has low hardness and low pH, can dissolve metals in water pipes and fixtures into tap water, especially with newly installed pipes
- Erosion of natural deposits and waste streams from industrial activity can increase copper levels in water as well
How to Remove It
Water filters certified under the following NSF standards are effective at removing Copper:
Health Guideline Level
The HGL 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
Copper is classified as a Metals contaminant.
This contaminant primarily affects the kidneys, gastrointestinal, and other systems.
