The only surefire way to know is to have your water tested. But in the meantime, here are some signs you need to call a professional.
1. Do your Hands Feel Slimy or Like They Have a Film After Washing Them?
Hard water isn’t always a sign of contamination, but may indicate high levels of lead, manganese or aluminum.
2. Orange, Yellow or Brown Water
Yellow may indicate contamination with chromium-6, a known carcinogen, or due to a buildup of lead or copper. Brown may indicate excessive rust and/or bacteria.
3. Blue or Green Water
Water that has a tinge of green or blue could indicate corroded pipes and a leaching of copper into your water. Overtime this can cause kidney and liver issues and well as anemia.
4. Smells Like Bleach
This is indicative of excess chlorination, the byproducts of which (such as trihalomethanes, or THMs) can cause cancer and kidney issues. Other byproducts such as haloaectic acids can cause skin irritation and increase the risk of cancer.
5. Smells Like Sulfur or Rotten Eggs
This could mean the presence of a colorless gas known as hydrogen sulfide. Although naturally occurring, it can cause problems.
6. Fishy Smells
Could be a sign of excess cadmium or barium, known to cause muscle weakness, heart, kidney and liver damage as well as increased blood pressure.
7. Metallic Taste
May suggest the presence of excess copper or iron.
