what about tds level meaning

TDS Level (Milligram/Litter)	Palatability of Water
Less than 300	Excellent
300-500	Good
600-900	Fair
900-1200	Poor
Above 1200	Unacceptable

Note: The Palatability of Water only describes the acceptability of the taste of water. It does not mean this should be healthy or unhealthy.

TDS Level in Drinking Water – Acceptable & Unacceptable

TDS Level (Milligram/Litter)	Remarks
Less than 50	Unacceptable because of lack of important minerals
50 – 150	Acceptable for Drinking (Excellent – where water is polluted with industrial wastes and sewage)
150 – 250	Good – Acceptable for Drinking (Healthiest in regard to cardiovascular health.)
250 – 350	Good – Acceptable drinking (Healthy in regard to cardiovascular health.)
350 – 500	Fair
500 – 900	Less Acceptable for Drinking
900 – 1200	Least acceptable for drinking; try to avoid drinking water with TDS level above 900 wherever possible
1200 – 2000	Very Least acceptable for drinking where other water sources are not available.
Above 2000	Unacceptable for drinking

1. The Upper Limit of TDS level in drinking water set by Bureau of Indian Standards (BIS) is 500 ppm (500 milligrams per liter).
2. If water TDS level is less than 100, it may result in hair fall and heart diseases.
3. Water with TDS level less than 100 has the high dissolvent capacity, which even dissolves a small quantity of plastic, in which it is kept. The dissolved plastic in water can cause cancer and can also reduce immunity. Plastic in water can also become a carrier for other toxins, heavy metals, arsenic, fluoride, or aluminum.

Verdict

However, there are different recommendations prescribed by different governments and organizations. In my personal opinion, nowadays water is polluted with chemicals, industrial waste, sewage, etc., which is actually very harmful to our health. It applies especially to India where industries are poorly regulated for disposal of these waste matters.

The above-suggested table should be fine where there is no water pollution. Otherwise, the following table is most recommendable in my personal opinion.
