Snails breathe oxygen, just like we do. Some use lungs and others use gills for breathing. You'd think that land snails would use lungs and pond snails would use gills, but it's not that simple. You'll find some of each kind both above and below the surface of the water. You'll have to decide what you think about our snails' breathing method. If they touch the surface every once in a while, they have lungs. If they never come up, they are either dead or breathe using gills. Since there are over 4000 species (types) of freshwater snails, and they are very difficult to tell apart, I cannot tell you what kinds we have.
