Perfluorinated Compounds: A Key Target for Emerging Pollutant Control During China’s 15th Five-Year Plan (2026–2030)

Unlike conventional pollutants such as COD, ammonia nitrogen, and total phosphorus, perfluorinated compounds (PFCs) feature extremely stable carbon–fluorine (C–F) bonds. Conventional biological treatment, coagulation, and sedimentation are virtually ineffective against them. Their environmental half-life spans several decades; they bioaccumulate progressively through aquatic systems → soil → food chains, posing potential risks to human immune function, endocrine systems, and reproductive development. PFCs thus represent a global challenge in drinking water and wastewater treatment. 2 Real-world challenges: High industrial wastewater concentrations, absence of national standards, and lack of regulatory basis for treatment The industry currently faces three core contradictions: 1. Widespread high concentrations: Perfluorinated compounds in raw wastewater from manufacturing enterprises, in wastewater entering industrial parks, and in final effluent commonly reach μg/L to mg/L levels—far exceeding drinking water reference limits and international control benchmarks. Conventional treatment processes achieve insufficient removal rates, allowing these substances to readily enter the environment and drinking water sources via discharge. 2. Absence of national discharge standards: Current national standards—including the Integrated Wastewater Discharge Standard, sector-specific discharge standards, and municipal wastewater treatment plant standards—do not stipulate any limit values for perfluorinated compounds. Only some provinces, municipalities, or industrial parks have issued provisional local requirements. Enterprises therefore operate “without applicable standards and without verifiable benchmarks,” resulting in ambiguous enforcement boundaries and compliance uncertainty. 3. Immature and costly treatment technologies: Conventional activated carbon and reverse osmosis show limited efficacy against short-chain PFAS and risk generating concentrated liquid waste or solid waste secondary pollution. Advanced technologies—including mineralization, oxidation, thermal decomposition, and ion exchange—are still undergoing pilot-scale demonstration and large-scale validation, with high capital investment and operational costs. At the potable water end (drinking water and tap water), analytical methods and health-based guidance values already exist. Yet at the wastewater and industrial discharge end, regulation and treatment remain weak links—without source control and end-of-pipe treatment, perfluorinated compounds will persistently re-enter the water cycle, becoming a long-term environmental hazard. 3 Regulatory trend: Standards accelerating, requiring enterprises to “act early and comply ahead of time” Although a nationwide uniform discharge limit has yet to be promulgated, regulatory signals are unequivocal: • Multiple regions have launched environmental surveys on perfluorinated compounds, conducted industrial park-level inspections, and initiated monitoring of key enterprises; • Local standards, industrial association standards, and internal park control standards are rapidly filling the gap, specifying discharge limits for critical substances such as PFOS and PFOA; • During the 15th Five-Year Plan period, China will complete its emission standard system for emerging pollutants—with perfluorinated compounds inevitably assigned enforceable limits and subject to strict oversight. Enterprises must “establish standards and build capacity ahead of time” to avoid being forced into retrofitting or production suspension once policies take effect. 4 Industrial wastewater treatment for perfluorinated compounds: Source reduction + advanced treatment + compliance management In light of current technological capabilities and policy directions, enterprises should adopt a stepwise strategy that is steady, precise, and cost-efficient: 1) Source substitution and process control (most economical and effective) Prioritize replacing high-risk PFAS-containing auxiliaries, cleaning agents, coatings, and water-repellent agents; optimize formulations and production processes to reduce both usage and loss of perfluorinated substances; implement segregated wastewater collection (e.g., separating high-concentration streams from general wastewater) and separation of clean and polluted water flows—thereby preventing dilution of high-PFAS wastewater into integrated treatment systems and lowering end-of-pipe treatment loads.

Human Rights Experts: U.S. Companies DuPont and Chemours Caused Widespread Toxic 'Forever Chemicals' Pollution in North Carolina

On 21 February 2024, multiple United Nations experts stated that U.S. chemical companies DuPont and Chemours had discharged toxic per- and polyfluoroalkyl substances (PFAS) into the environment, completely disregarding the rights and well-being of residents downstream of the Cape Fear River in North Carolina. According to reports, community members in the area have been unable to access clean and safe water for decades. Marcos A. Orellana, UN Special Rapporteur on Toxics and Human Rights, and six other experts said: “Despite DuPont and Chemours’ awareness of the toxic impacts of PFAS on human health and drinking water supplies, these companies continue producing and discharging such substances.” The experts noted that, for decades, DuPont and Chemours have manufactured, sold, and profited from PFAS—exacerbating this global toxic pollution crisis. The serious risks and harms posed by PFAS to communities worldwide should be addressed at the upcoming United Nations Environment Assembly. What are per- and polyfluoroalkyl substances? PFAS are found in personal care products such as shampoos and dental floss; cosmetics including nail polish and eye makeup; certain plastics; grease-resistant paper; fast-food containers; carpets; upholstery; and other fabric treatments designed to repel stains and water. This class of toxic chemicals is also known as “forever chemicals” due to their extreme persistence—meaning they do not readily degrade in nature and may cause harm for decades or even centuries. UN experts expressed alarm over the Netherlands’ export of hazardous PFAS waste to the United States—a move that clearly violates international law. Regulatory agencies failed in their duties The experts stated: “DuPont and Chemours appear to have unreasonably captured the U.S. Environmental Protection Agency (EPA), delaying its appropriate regulatory efforts concerning PFAS chemicals.” They emphasized that U.S. health and environmental regulatory agencies have failed in their duty to prevent business-related human rights abuses—including their failure to provide affected communities, especially those in North Carolina, with relevant and adequate information necessary to prevent harm and seek redress.

North Carolina demands stronger action from Chemours on toxic PFAS

1 day ago

North Carolina's environmental agency ordered Chemours to implement nearly 40 new cleanup requirements for toxic PFAS contamination affecting over half a million residents, despite a prior $600 million settlement.
