Water quality in Ahmedabad
Where 1731 mg/L sits
Your area reads Severe. 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
Ahmedabad tap today
~1731mg/L
After RO purification
~87–173mg/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 Ahmedabad
Taste
Often salty or bitter, with a heavy mineral aftertaste.
Health
Well above safe limits — long-term use is not advisable without purification.
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
| 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 high salinity, fluoride, nitrate above BIS limits at one or more locations in the Ahmedabad 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 Ahmedabad?
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.

Among the cities we map, Ahmedabad has the 2nd highest average groundwater TDS — about 3.5× the BIS acceptable limit of 500 mg/L, against a median of 673 mg/L across those cities.
Individual monitoring points around Ahmedabad range from 227 to 3900 mg/L. An average hides that spread, so your own borewell or municipal line can read well above or below 1731 mg/L — one more reason to test your actual supply.
Elsewhere in Gujarat, Surat averages ~1801 mg/L, Rajkot ~1100 mg/L and Vadodara ~800 mg/L.
06 · Best fit for Ahmedabad
Boon Tall
from ₹49,000
TDS here averages ~1731 mg/L, above the BIS limit of 500, so a reverse-osmosis (RO) purifier like Boon Tall is recommended.
Ahmedabad water — questions
What is the TDS of water in Ahmedabad?
Groundwater near Ahmedabad has an average TDS of about 1731 mg/L, above 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 227 to 3900 mg/L across nearby monitoring points.
Is tap water safe to drink in Ahmedabad?
With TDS around 1731 mg/L (above the BIS limit of 500), water in Ahmedabad 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 Ahmedabad?
Yes. High TDS or hardness in Ahmedabad means reverse osmosis (RO) is the appropriate technology to bring water within safe, palatable limits.
