TDS below 500 mg/l of water is safe and recommended. Water with no TDS will be of no health effect moreover, it be trustworthy for nil contamination. TDS are total dissolved solids in water. We get dissolved solids from food so it is not necessarily a requirement of water. Rain water contains no TDS. However, its pH should be under 7-8.5. As water without TDS are sometime acidic in nature because of dissolved carbon dioxide in it.
