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

What an RO purifier changes

Kanpur tap today
~650 mg/L
After RO purification
~33–65 mg/L

An RO membrane typically removes 90–95% of dissolved solids, bringing water into the ideal drinking band. Boon purifiers remineralise after RO so the water isn’t stripped flat.

What this means for you in Kanpur

Taste

Noticeably hard, with a flat or mineral taste.

Health

Above the BIS limit — purification is recommended for regular drinking.

Appliances

Promotes scaling (white deposits) on taps, geysers, kettles and RO membranes.

What to use

A reverse-osmosis (RO) purifier is the right fit here.

Other parameters that matter

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

Parameter
BIS limit
Why it matters
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.

Regional watch

The CGWB Annual Ground Water Quality Report (2023 monitoring) flagged nitrate, fluoride, iron above BIS limits at one or more locations in the Kanpur district. If you draw borewell water, get these tested specifically.

Microbiological note

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

Why is TDS like this in Kanpur?

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. City taps often blend treated municipal supply with borewell water, so two buildings on the same street can read very differently — and levels shift with the seasons, usually peaking just before the monsoon. The figure above is an indicative area reading from government monitoring, so your own tap can differ; testing it twice a year is a good habit. Read our full guide to TDS & how to reduce it ›

Kanpur water — questions

What is the TDS of water in Kanpur?
Groundwater near Kanpur has an average TDS of about 650 mg/L, above the BIS acceptable limit of 500 mg/L, based on government monitoring data (CGWB Kanpur Nagar district brochure (EC-derived), 2009). Levels range roughly 301 to 998 mg/L across nearby monitoring points.
Is tap water safe to drink in Kanpur?
With TDS around 650 mg/L (above the BIS limit of 500), water in Kanpur is generally not ideal for direct drinking, so an RO purifier is recommended. Always test your own supply.
Do I need an RO water purifier in Kanpur?
Yes. High TDS or hardness in Kanpur means reverse osmosis (RO) is the appropriate technology to bring water within safe, palatable limits.
