Fluoride
Long use stains and pits teeth (dental fluorosis) and can stiffen bones and joints (skeletal fluorosis).
17 districts of Punjab had at least one groundwater sample with fluoride above the BIS drinking water limit (over 1.5 mg/l) in CGWB's pre-monsoon 2023 tests. Across the state, 13.77% of 922 samples were over 1.5 mg/l.

RO or activated alumina filters remove fluoride; rainwater, which has almost none, is a safe drinking source when stored clean.
Rainwater has almost no dissolved salts or fluoride. Stored clean it is safe drinking water, and recharged it slowly freshens the aquifer.
CGWB's 2024 report found fluoride above the limit in groundwater samples from 17 districts of Punjab: Amritsar, Bathinda, Faridkot, Fatehgarh Sahib, Gurdaspur, Hoshiarpur, Jalandhar, Mansa, Moga, Muktsar, Patiala, Sangrur, Tarn Taran, Fazilka, SAS Nagar, Firozpur, SBS Nagar.
Not without testing. Water from one borewell can be fine while the next is not. Test at a NABL-accredited lab or the Public Health Engineering department, and treat it if it fails. RO or activated alumina filters remove fluoride; rainwater, which has almost none, is a safe drinking source when stored clean.
