Query on water softener

Borewell water changed after the rains


I dug a bore well and got water at 900 feet. After the rains it has become hard and on testing CaCO3 is more, Calcium 80 (range 75) Magnesium is twice more. Please suggest the ways to make it potable for drinking and bathroom use.

Thank you in anticipation.
