Did you get your water tested at a reputable laboratory? If so in addition to the bacti tests and the general water chemistry tests (pH, conductivity, Colour, Turbidity, Hardness, Nitrates, Ammonia etc) you should also test for metals such as Iron and Manganese and also Arsenic and Lead.
Show these results to a number of reputable water treatment contractors in your area and get quotations which include exact specifications, running costs and guarantees.
