Pool water turning hair green

It's a hot weekend. So it has been decided that there will be a pool party for the family. Everyone had an awesome time. However, at the end of the day, their blonde hair has been tinted green. Sensibly, you wonder what happened.
Pool water turning hair green is not uncommon. Swimmers normally suffer from this problem. Most people assume that this is from chlorine in the water. Not a surprising assumption considering pool water is highly chlorinated. However, chlorine is not really the problem. The cause of greening is copper. Okay. I guess we could say that chlorine is partially responsible. Because what causes greening is the oxidation of copper by chlorine.
The oxidized copper then binds unto the strands of the hair. Those with blonde hair, the greening can be quite noticeable.
Water contamination has many signs. Most people know to be wary about unusual color, flavor, and odor of drinking water. But about water not used for drinking?
Just because water is not used for consumption does not mean people should not care what is in it. Some contaminants can harm you even if you don't drink the water. Take radon for example. The radioactive gas is naturally found deposited underground where it can contaminate groundwater. The dissolved radon from the water can escape to the air. Inhalation of radon can cause lung problems.
It is important to know about other signs of contamination as these can tell you what type of contaminant is potentially in the water even before a water analysis is done.
