Understanding PFAS: The Danger of Forever Chemicals
Per- and polyfluoroalkyl substances, universally abbreviated as PFAS, are a class of thousands of synthetic organofluorine compounds. Widely used since the 1950s in non-stick cookware, waterproof textiles, firefighting foams, and stain-resistant coatings, PFAS chemicals possess unique water- and oil-repellent properties.
However, the defining characteristic of PFAS is the carbon-fluorine bond, one of the single strongest single bonds in organic chemistry. Because nature has no natural biological or chemical mechanism to break this bond down, PFAS chemicals never decompose naturally. Once discharged into water bodies, they persist indefinitely, earning the name forever chemicals. They travel long distances through aquifers and bioaccumulate in the blood and organs of humans and livestock, linked by international health bodies to kidney cancer, testicular cancer, thyroid dysfunction, and immune suppression.
The Miteni Disaster: Italy's Major PFAS Contamination Scandal
For over five decades, chemical manufacturer Miteni S.p.A. operated a large fluorochemical production facility in Trissino, located in the Veneto region of northern Italy. Untreated chemical runoff and subterranean leakage from the facility infiltrated the local underground water table, contaminating the drinking water supply for approximately 350,000 residents across 30 municipalities.
In 2013, environmental surveys confirmed massive PFOA and PFOS contamination in regional aquifers. Facing overwhelming public outcry, civil lawsuits, and billions of Euros in mandatory cleanup costs, Miteni declared bankruptcy in November 2018. In June 2025, Italian criminal courts delivered a historic verdict, sentencing eleven former Miteni executives to prison terms of up to 17 years for toxic water pollution and environmental bankruptcy.
The Relocation: Shipping 300+ Containers from Italy to India
In June 2019, Indian chemical firm Laxmi Organic Industries, operating through its subsidiary Viva Lifesciences, purchased selected assets of the bankrupt Miteni plant at an Italian court auction for 3.65 million Euros (approximately 28 crore Rupees). The purchase included chemical reactors, distillation columns, technical blueprints, patents, and REACH registrations.
Laxmi Organic dismantled the Italian facility, packed the machinery into over 300 shipping containers, and transported the equipment across the sea to India. The machinery was installed at a site in the Lote Parshuram MIDC industrial belt in Ratnagiri district, Maharashtra, starting production around 2024-2025.
While European regulators tightened environmental oversight and forced the closure of legacy PFAS manufacturing units, chemical firms leveraged regulatory gaps in South Asia to acquire established production assets at steep discounts. This highlights a growing global trend where hazardous chemical manufacturing migrates to countries lacking statutory limits.
Comparing Regulatory Frameworks: Global Strictness vs Indian Vacuum
The relocation of the Miteni plant underscores a dramatic regulatory gap between international standards and Indian environmental law:
| Jurisdiction | Regulatory Body | Drinking Water Limit (PFOA/PFOS) | Industrial Discharge Mandate |
|---|---|---|---|
| United States | US EPA | 4 ppt (4 ng/L) Enforceable MCL | Mandatory NPDES Industrial Monitoring |
| European Union | EU Water Directive | 100 ppt (Total PFAS) | REACH Restrictions & ZLD Rules |
| India | CPCB / BIS (IS 10500) | No Limit Specified (0 ppt Rule) | No Mandatory PFAS Testing Specified |
In India, municipal drinking water standards (IS 10500:2012) and Central Pollution Control Board (CPCB) effluent norms specify strict thresholds for heavy metals, pesticides, BOD, and COD, but completely omit PFAS compounds. Standard State Pollution Control Board (SPCB) laboratories are not equipped with Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) systems required to detect trace PFAS concentrations at parts-per-trillion levels.
Corporate Response & Official Positions
Laxmi Organic Industries has repeatedly rejected comparisons to the Italian disaster, stating that its Lote Parshuram facility operates under modern closed-loop design standards, strictly adhering to zero-liquid-discharge (ZLD) norms and local pollution board consent orders. In February 2026, the Indian government stated in the Rajya Sabha that environmental inspections by the Maharashtra State Pollution Control Board (MPCB) confirmed the facility was operating within consented statutory parameters.
However, environmental scientists point out that standard BOD and COD compliance tests do not detect PFAS. Because forever chemicals pass through conventional biological wastewater treatment systems completely unchanged, standard compliance certificates do not verify the absence of fluorinated compounds in surrounding water bodies.
Engineering Solutions: How to Detect and Treat PFAS
Protecting water basins from PFAS accumulation requires specialized analytical testing and advanced physical-chemical treatment technologies:
1. High-Sensitivity Baseline Testing (LC-MS/MS)
Standard testing methods cannot measure parts per trillion. Facilities must utilize Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) operating under EPA Method 533 or 537.1 to quantify specific PFAS short-chain and long-chain target compounds.
2. Granular Activated Carbon (GAC) Adsorption
Passing effluent through virgin bituminous coal-based GAC beds provides high surface area for adsorbing long-chain PFAS compounds like PFOA and PFOS.
3. Ion-Exchange (IX) Synthetic Resins
Single-use or regenerable synthetic anion exchange resins offer fast kinetics and high capacity for capturing short-chain fluorinated acids that slip past carbon beds.
4. High-Pressure Reverse Osmosis & Thermal Incineration
Dense polyamide RO membranes achieve over 99% PFAS rejection. The resulting concentrated brine stream must be treated via high-temperature thermal incineration at temperatures exceeding 1,000 degrees Celsius to cleave the carbon-fluorine bond.
