Your area reads Very low. BIS rates water up to 500 mg/L as acceptable and 150–300 mg/L as ideal for taste and health.

What this means for you in Dehradun

Taste

Generally clean and light to drink.

Health

Within safe limits, though local supply can vary by season and building.

Appliances

Low scaling risk on taps and appliances.

What to use

A UV/UF purifier is usually enough; RO with mineral balance still helps.

Other parameters that matter

TDS is the headline number, but drinking-water safety also depends on these (BIS IS 10500 limits):

Bacteriological (E. coli / coliform)

Nil in any 100 ml

Causes stomach infections; needs UV or boiling.

Fluoride

1.0 mg/L (max 1.5)

Excess causes dental & skeletal fluorosis.

Arsenic

0.01 mg/L

Toxic; long-term exposure is carcinogenic.

Nitrate

45 mg/L

Risky for infants (blue-baby syndrome).

Iron

0.3 mg/L

Metallic taste, staining of fixtures & clothes.

Total hardness

200 mg/L (max 600)

Scaling on taps, geysers & appliances.

Microbiological note: bacterial safety (E. coli/coliform) is not part of chemical groundwater monitoring — it needs a lab test of your own tap, and varies with pipe leaks and monsoon. UV purification (built into Boon Tap) inactivates bacteria and viruses; RO removes the dissolved contaminants above.

Why is TDS like this in Dehradun?

Most Indian cities draw heavily on groundwater, which dissolves minerals and salts from the soil and rock it sits in. Over-extraction, ageing pipes and local geology push dissolved solids (TDS), hardness and sometimes fluoride, nitrate or arsenic above safe limits. Levels also shift between seasons. The figure above is an indicative area reading from government monitoring — your own tap can differ, so it’s worth testing.

Dehradun water — questions

What is the TDS of water in Dehradun?

Groundwater near Dehradun has an average TDS of about 140 mg/L, within the BIS acceptable limit of 500 mg/L, based on government monitoring data (CGWB groundwater monitoring 2018-2021 (EC-derived TDS), 2021). Levels range roughly 128–153 mg/L across nearby monitoring points.

Is tap water safe to drink in Dehradun?

TDS around 140 mg/L is within BIS limits, but municipal/borewell supply varies by building and season — test your own water and use a purifier with monitoring to be sure.

Do I need an RO water purifier in Dehradun?

Possibly not for TDS alone, but an RO purifier with mineral balance still protects against seasonal spikes and other contaminants in Dehradun.
