Yes, copper can turn water green, or sometimes blue-green.
How Copper Affects Water Color
When copper pipes corrode, copper dissolves into the water supply. This dissolution can lead to a visible blueish-greenish tint in the water. The reference states: "If your home's water has higher-than-normal copper levels, it's most likely due to corroded copper pipes. You see, as the pipes corrode, copper dissolves into the water that's transported into your home giving it that blueish-greenish tint."
Identifying Copper in Your Water
- Visual Inspection: Look for a blue-green tint, especially in standing water (e.g., in tubs or sinks).
- Plumbing Age: Older homes with copper pipes are more prone to corrosion.
- Testing: A water test can confirm the presence and concentration of copper.
Potential Issues and Solutions
High copper levels in water can pose health risks and cause staining of fixtures. Here are some steps you can take:
- Run the Water: Flush the pipes by running the water for a few minutes, especially after periods of non-use.
- Water Testing: Get your water tested to determine the copper level.
- Corrosion Control: Consider a whole-house water filter or other corrosion control measures.
- Plumbing Upgrade: In severe cases, replacing old copper pipes with alternatives like PEX or CPVC might be necessary.
