What is that white layer of film that I get when boiling water?

Question

I normally drink lots of tap water. I recently moved to an apartment that is only about 10 miles away from my old house. Here, the water looks and tastes the same as before. The problem is that I'm getting grossed out because I'm noticing that whenever there's a need to boil water, a white layer of some sort of film develops around the inside of the pan at the level where the water reaches. This also happens on mugs when I microwave water for tea or whatever. I'm using the same pans and mugs that I've always used. What is that?

Answer 1

The water sometime has acid, which is normally found in the water area of the locality. When you boil the water that acid ingradient appears on the surface of the water in the shape of a film. This type of water is found when the water level is not far from surface of the land.

Answer 2

probably its flourin and chlorin depending on ur area of apartment and the water supply there.

Answer 3

old toilet paper fibers clumping together when you boil the water. Kind of like how they make paper.

Answer 4

plastic thats it. that plastic from the pipes particularly PVC pipes, they wear away when great force pass on the surface and plastic easily breaks down into simpler components known as monomers which forms the white layer thingy.

Answer 5

Haha, I always thought that was normal. I've been drinking it for 20 years, and nothing bad has happened to me. (Aside from the hideous disfigurement and mental retardation.)

Answer 6

calcium
