Brown running water does ...

 

Brown running water does mean your water "is" contaminated. But don't press the panic button.

i.  Might be due to a rusty pipe line. Please check with a plumber if incase you have metal pipes concealed as this might lead to cracks and leakage, consequently.

ii. Too much iron make the water look brown or reddish brown. Though these are contaminants, they don't harm our health as these minerals are essential.

Potential solution:

Chlorinate and filter (RO) the water. Iron is oxidized by Chlorine. And RO is not the healthiest drinking water, as it is apparent.

Although present in drinking water , iron is seldom found at concentrations greater than 10 milligrams per liter (mg/L) or 10 parts per million. However, as little as 0.3 mg/l can cause water to turn a reddish brown colour.

Hope this helps.
