The message is incredibly simple. Leave three 2 liter vases of local tap water standing to rid the trace amounts of chlorine. Use these containers of water in rotation for all drinking and cooking purposes. Don't buy another plastic water bottle again... ever. You will also eliminate Biphenol leakage into your diet, make a serious dent in landfills, and save enough money to go camping for a month. In India it is (still, I hope) against the law to deny anyone a drink of your water.
