Environmental Groups Urge EPA to Reject New PFAS for Data Centers

A coalition of 17 environmental organizations has formally urged the U.S. Environmental Protection Agency (EPA) to reject a new per- and polyfluoroalkyl substance (PFAS) proposed by the chemical company Chemours. The proposed PFAS is intended for use in cooling data centers, a rapidly expanding industry. The environmental groups, including Earthjustice, argue that Chemours has downplayed the significant health and climate risks associated with this new chemical in its bid for fast-track approval. In formal comments submitted to the EPA, the coalition asserts that Chemours has utilized flawed science to minimize the chemical's toxicity and its potential impact on the climate. Earthjustice, acting as a lead author of these comments, stated that approving Chemours' application in its current form would contravene existing environmental laws. The groups are concerned that the widespread use of this new PFAS would inevitably lead to pollution in regions surrounding data center facilities. Data centers, which house the servers and infrastructure for the internet and digital services, require substantial cooling systems to prevent overheating. These cooling systems often rely on specialized fluids, and PFAS chemicals have been historically used for their heat-transfer properties. However, PFAS are known for their extreme persistence in the environment, earning them the nickname 'forever chemicals.' They do not break down easily and can accumulate in soil, water, and living organisms, leading to a range of adverse health effects, including immune system suppression, developmental issues, and increased risk of certain cancers. The environmental advocates contend that introducing another persistent chemical into the environment, particularly for an industry with a growing footprint like data centers, is irresponsible and poses an unacceptable risk. They are calling on the EPA to uphold its legal obligations and prioritize public health and environmental protection over the expedited approval of potentially harmful substances. The submission of these formal comments marks a critical juncture in the EPA's review process, where public input and scientific evidence are intended to inform regulatory decisions. The coalition's detailed objections highlight concerns about the long-term environmental consequences and potential human health impacts that could arise from the widespread deployment of this new PFAS compound.
