use a clarifying shampoo once or twice a week, pending on how bad the water is and the condition of your hair.
getting a protein treatment every other week will help keep nutrients in your hair.
if they minerals in the water are effecting the color of your hair, there are special toner shampoos that can help keep unwanted colors out of your hair.
ex: if you have blond hair, and water is giving it a brassy yellow tone, there is a silver toner shampoo (it's purple/blue based, to counteract the yellow), do not use daily, and pending on the porosity of your hair use it once a week to once every other week.
