That isn’t so lovely.
High levels of copper in water are usually found when copper or brass plumbing has begun to corrode. The blue-green stain is actually copper residue. When acid water passes through pipes, it dissolves the copper in the pipe potentially causing pinhole leaks in your plumbing.
If you’re unsure whether copper has infiltrated your water, here are a few signs:
- Metallic tasting water
- Blue-green stains on your fixtures
- Color variations in your hair tones – especially blondes
- Corrosion of aluminum surface
