water treatment occurs in many ways. water around the world varry greatly and so does the process of purification. some of the more common methods include boiling, distillation and revese osmosis. boiling is pretty self explanitory and removes some impurities but anything not too large will not boil out and should be filtered. distillation is again the process of boiling water but instead of just using the boiled water it collects the steam and comdenses it. reverse osmosis uses water pressure to push water molocules through an extremely small membrane leaving the impurities behind. Eaton Rapids water comes from 5 ground water wells located a little north of the city. other cities get water from underground aquifers or pull from lakes and rivers.
