Whether blue water is safe to drink depends on the cause of the discoloration. Generally, blue water is not considered safe to drink until the cause is identified and addressed.
Here's a breakdown:
-
Potential Cause: Copper Plumbing
- The most common reason for blue-tinted water is the presence of elevated copper levels, often from corroding copper pipes.
- This is more likely to occur in homes with newer copper plumbing.
- Why it happens: When water sits in copper pipes for extended periods, it can leach copper, resulting in a blue tint.
- What to do:
- Run the tap for a few minutes to flush out the discolored water. If the blue color disappears, it's likely due to copper leaching.
- If the blue color persists, further investigation is needed.
- Health Concerns: High levels of copper in drinking water can cause gastrointestinal issues like nausea, vomiting, and diarrhea. Long-term exposure to high copper levels can lead to more serious health problems.

When to Contact Your Water Supplier
- If the blue color doesn't disappear after running the tap.
- If you notice a metallic taste in the water.
- If you experience gastrointestinal symptoms after drinking the water.
- If you are concerned about the safety of your water.
-
Testing Your Water:
- A water test can accurately determine the levels of copper and other contaminants in your water.
- Contact your local health department or a certified laboratory for water testing services.
In summary, while the blue color itself may be due to copper, it indicates a potential health hazard. Don't drink blue water without investigating the cause and ensuring it's safe.
