\u2014 have been found in water sources across multiple Indian states, yet India\u2019s water treatment systems and regulatory framework remain ill-equipped to detect or remove them.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">With no PFAS-specific drinking-water limit currently in place, this emerging contamination issue carries significant public health and policy implications.<\/span><\/li>\n<\/ul>\n<h2><b>What Are PFAS?<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PFAS are <\/span><b>synthetic chemical compounds<\/b><span style=\"font-weight: 400;\"> containing <\/span><b>multiple carbon-fluorine bonds<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Used widely in coatings, textiles, and industrial products.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Notorious for resisting degradation \u2014 they can contaminate the environment for decades, earning the \u201cforever chemicals\u201d label.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PFAS have existed for 60 years, yet regulation has lagged behind their spread.<\/span><\/li>\n<\/ul>\n<h2><b>Health Concerns: What We Know<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In 2025, the International Agency for Research on Cancer (IARC) classified:\u00a0<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><b>Perfluorooctanoic acid<\/b><span style=\"font-weight: 400;\"> (PFOA) as

carcinogenic to humans.\u201d<\/span><\/li>\n<\/ul>\n<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Important caveat: Merely detecting PFAS in water doesn\u2019t indicate health risk by itself \u2014 risk depends on the type of PFAS, dose, duration, and route of exposure.<\/span>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"2\"><span style=\"font-weight: 400;\">A February 2026 study found that a mix of 24 PFAS compounds delayed zebrafish egg hatching, inhibited offspring growth, accumulated in blood, and reduced heart rates \u2014 raising concerns about broader ecological and health impacts.<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2><b>Evidence of Contamination Across India<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A 2025 review in the Journal of Hazardous Materials Advances examined monitoring across Gujarat, Maharashtra, Tamil Nadu, and West Bengal.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Key finding: PFAS contamination is a \u201clegitimate concern,\u201d but its national extent remains poorly defined \u2014 partly due to inconsistent testing and analysis methods across research groups.<\/span><\/li>\n<\/ul>\n<h3><b>IIT-Madras Study (2024)<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Analysed 14 water samples (2022\u201323) from groundwater, surface water, and four stages of a water treatment plant.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Groundwater near garbage dumps showed the highest PFAS levels.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Startling finding: <\/span><span style=\"font-weight: 400;\">PFAS concentrations were 5% to 103% HIGHER in treated water than raw water<\/span><span style=\"font-weight: 400;\"> \u2014 suggesting treatment processes may convert unidentified precursors into more stable PFAS.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Researchers noted the 8 target PFAS tested represent only a fraction of potentially diverse fluorinated compounds present \u2014 broader testing beyond fixed lists is needed.<\/span><\/li>\n<\/ul>\n<h2><b>Why Treatment Systems Are Failing<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Conventional biological wastewater treatment cannot remove PFAS.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Adsorption-based treatment shows potential but low-cost materials for PFAS capture are still under development.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Testing against a fixed list of PFAS risks missing undetected substances, since precursors can transform into other PFAS over time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">High-resolution mass spectrometry can help identify PFAS beyond fixed lists, but requires care since PFAS can contaminate samples during collection\/analysis itself.<\/span><\/li>\n<\/ul>\n<h2><b>India\u2019s Regulatory Response: Work in Progress<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Union Environment Ministry has confirmed there is <\/span><b>no specific regulation<\/b><span style=\"font-weight: 400;\"> banning PFAS manufacturing.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India has <\/span><b>no PFAS-specific drinking-water limit<\/b><span style=\"font-weight: 400;\"> under the current IS 10500:2012 standard \u2014 though this standard is under revision.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The Bureau of Indian Standards (BIS) has formed a dedicated Working Group on Emerging Contaminants and Forever Chemicals to examine PFAS limits.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Scope and specific PFAS to be regulated have not yet been finalised; analytical testing methods are also under consideration.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">CSIR-Indian Institute of Toxicology Research (IITR), Lucknow is participating in a UNEP-funded National Implementation Plan to build baseline PFAS data, and has developed capability to detect 50 multi-class PFAS molecules.<\/span><\/li>\n<\/ul>\n<h2><b>Conclusion<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India\u2019s PFAS problem is a textbook case of <\/span><b>regulation lagging behind contamination.<\/b><span style=\"font-weight: 400;\">\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Multiple independent studies have already flagged forever chemicals in groundwater, treated water, and coastal sewage, yet no enforceable drinking-water limit exists, and conventional treatment plants may even be inadvertently creating more stable PFAS compounds.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">With global health agencies now classifying key PFAS as carcinogenic, experts agree that waiting for complete exposure data before acting is no longer a defensible position \u2014 India needs precautionary interim limits, harmonised testing standards, and a clear accountability framework, well before full contamination mapping is complete.<\/span><\/li>\n<\/ul>\n<p><b>Source:<\/b> <strong><a href=\"https:\/\/epaper.thehindu.com\/reader\" target=\"_blank\" rel=\"nofollow noopener\">TH<\/a> | <a
