The Environmental Protection Agency (EPA) is currently facing significant legal challenges over its handling of toxic substances, particularly a group of chemicals known as PFAS (per- and polyfluoroalkyl substances), often called “forever chemicals” due to their persistence in the environment. These challenges raise the question of whether the EPA will be sued for failing to adequately regulate these toxins.
The situation is complex and evolving. The EPA has taken some regulatory actions, such as designating certain PFAS chemicals like PFOA and PFOS as hazardous substances under Superfund laws, which allows for cleanup and liability enforcement. The agency has reaffirmed its commitment to defending these designations in court despite opposition from industry groups. This move signals the EPA’s intent to hold polluters accountable for contamination and protect public health.
However, the EPA has also faced criticism and legal pushback for its approach to regulating other PFAS chemicals. For example, the agency recently requested that a federal court vacate parts of the Biden-era drinking water regulations that set maximum contaminant levels (MCLs) for four specific PFAS chemicals, arguing that some aspects of the rulemaking process were unlawful. This request to overturn protections for certain PFAS has sparked concern among environmental advocates and affected communities, who fear that weakening these standards could leave people exposed to harmful toxins.
Beyond PFAS, the EPA’s broader regulatory efforts have encountered obstacles. Lawsuits have challenged the agency’s decisions to terminate or reduce funding for environmental justice and pollution control programs, which are critical for protecting vulnerable communities from toxic exposures. Courts have sometimes sided against the EPA or delayed actions, creating legal uncertainty and slowing progress on pollution cleanup and prevention.
The legal battles reflect a tension between regulatory ambition and political, legal, and industry pressures. On one hand, there is growing scientific evidence and public demand for stronger controls on toxic chemicals to prevent health harms such as cancer, developmental issues, and environmental damage. On the other hand, the EPA’s authority is constrained by statutory limits, judicial scrutiny, and shifting policy priorities under different administrations.
Given this context, it is highly likely that the EPA will continue to be sued over its regulation—or perceived failure to regulate—various toxins. Lawsuits come from multiple fronts: environmental groups pushing for stricter protections, industry groups challenging regulatory overreach, and communities seeking redress for contamination. These legal challenges serve as a critical mechanism to hold the EPA accountable and shape how toxic substances are managed in the future.
