TDS Chart

TDS stands for Total Dissolved Solids. Some bottled water has TDS results information on the bottle.

TDS 0-50ppm – micro-filtered and distilled water

According to the US EPA’s TDS chart, 0-50ppm is considered micro-filtered and distilled water. TDS below 30ppm in the water can be unhealthy for your body, as the water does not have enough minerals that your body needs.

TDS 50 – 170ppm Carbon filtered, mountain spring or aquifers water

TDS 170 – 200ppm Hard Water – Marginally acceptable water

TDS 200 – 400ppm High TDS water from tap or mineral spring

The average tap water TDS content is 170-400. Water above 170ppm is hard water.

US EPA’s maximum contamination level is > 500ppm.
