 blue-green residue
Author: jamesah (WA)

My water leaves a significant blue-green residue in my sinks and tub. I'm on a municipal water system, so it has to be coming from my pipes.
What is this? Is there a health issue? How do I fix it?
thanks to anyone who has advice.
Jim

Contact the City and let them know. They are supposed to be controlling the corrosivity of the water. It is likely that the staining is caused by copper in the water from copper corrosion.

Run cold water at one of the sinks where you've noticed residue. Then run hot water. If it's coming out when using cold water only, I'd contact your water supplier. If it only shows up when running hot water only, I'd say it's anode rod breakdown.

Aggresive water.

I would check the ph of my water supply, because it sounds like you have high-acidity water. Which causes corrosion in copper water supply tubing. Eventually you'll have to replace your water supply piping. Esp. on the Hot water side.

I suggest your water supply is from surface water, and may even have a high iron content.

Call a water specialist and have your water treated.or plan on replacing the copper soon.Good Luck.Want a treat,Save this if the city asks you for a sample of your water.Turn the main supply of.drain the water from the system,by opening all the faucets.let it stand for a few minutes and then close all faucets open valve and send out all water to be tested from the farthest/highest fixture from the main shut off.It will tell the tale.

GSchreiber, CWSVI said it all!

"Contact the City and let them know. They are supposed to be controlling the corrosivity of the water. It is likely that the staining is caused by copper in the water from copper corrosion."

The water provider is supposed to control how aggressive the water is so you do not end up drinking your copper pipes.

Well,are you in a small isolated community?Your health may only be monitored at the service point.Find out who checks your water quality and who is responsible for it.Good Luck.Copper is not what I would worry about but the lead/antimony it is joined with may be leaching at high rates also.

When we had the problem in this area, it was a municipal water problem with nothing to do with the individual houses.
