What causes the brown of yellow tinge in my water at times?
There are naturally occurring mineral in your water. These include iron, manganese, calcium, chloride and other dissolved minerals. The dissolved iron in the water will react with the chlorine and come out of the dissolved state. This iron settles to the bottom of our pipes and will lay there until disturbed by unusually high flow rates, such as fire department use, or a break in the line. This causes the iron to mix back into the water and cause a yellow or brown tinge. This water, though unsightly, is not a public health threat. These incidences usually clear within a few hours. If the problem persists you can call the office to report the problem.
