Hi,
Currently we are using water from a deep tube well (800 feet). This water is sand filtered before being used for household purpose. For drinking water we have installed a RO purifier (Kent). The sand-filtered water leaves whitish spots on utensils and a feeling of roughness on body after bath. However the clothes (white) clothes do not get any stains.
The water analysis report is as mentioned below.
