Agree... we have very mineral rich water where I am and it looks more like precipitate/crystals/white grainy substance. If there is a white "film"or slimy looking substance, then that is probably not minerals, probably bacteria...Well, the OP was talking about a white film on the water - that's always bacteria, I never heard of any film being minerals. I'm not a geologist, so correct me if I'm wrong, but I would expect minerals to form crusts on surfaces - crystals in some form or other. Of course, I hereby assume the OPs interpretation that the 'white' still visible in the pic is the dried rest of it, to be wrong. Bacteria wipe off. The white stuff still left would be minerals, I agree.
Also the mineral deposits are not easy to wipe off usually, if that helps. IME a bacterial film would be relatively easy to remove
