Frequently Asked Questions - Water Quality

Is fluoride added to SWA water?

Yes, the Sewickley Water Authority does add Fluoride to the water.

Why does my drinking water sometimes look cloudy when first taken from a faucet and then clear up?

The cloudy water is caused by tiny air bubbles in the water similar to the gas bubbles in carbonated soft drinks.  AFTER a while, the bubbles rise to the top and are gone.   This type of cloudiness occurs more often in the winter because the colder water holds more dissolved air.

Air can be introduced into the water after pipe repairs or other service disruptions.

There is a "pink slime" in my shower. Is it from the water?

No, certain species of airborne bacteria gravitate towards and thrive in a moist environment, such as showers, toilet bowls, sink drains, tiles and dog dishes.  These bacteria are naturally occurring and unattractive, but are generally harmless.  The best way to avoid this problem is to keep the surfaces free from bacterial film through regular cleaning using Lysol or a chlorine-based product.

What are the black spots, rings, or lines in toilets and shower stalls?

Mold and mildew grows in places that are continually damp and is treated the same as the pink slime.
