Need methods to improve water quality from RO purifier in a village - Test report attached

Please find attached the water test report concerning the bore water from our village. Our village does not have access to pure drinking water and with a view to providing the same a trust was formed. The current method of purification using a R.O. plant and "hyrdronautics cpa2 40-40 membranes" is not suitable for consumption. Kindly advice on what methods can be adopted to improve the water quality and make it acceptable to all the users.

Suggestions may also be provided to make sure that the remedy is economically feasible.
