Conor right here: A typical sense resolution that the US is after all not solely not pursuing, however transferring additional away from. And sadly that is one other difficulty the place RFK Jr. has been heading in the right direction, but it surely appears the administration solely values his worst concepts.
The next piece makes the argument that wastewater remedy vegetation have the authority to behave however aren’t doing so. Whereas the argument makes excellent sense from a public well being viewpoint, there are after all financial roadblocks, such because the concern that requiring industrial clients to regulate PFAS air pollution would trigger them to maneuver to a extra “pleasant” locale.

A category of humanmade compounds — referred to as PFAS, or perpetually chemical compounds — are insidious and dangerous, and native U.S. wastewater utilities are possible giving them a free experience into ingesting water and meals. Nationwide — in states similar to Maine, Michigan, and Texas — sewage sludge from wastewater vegetation that’s contaminated with per- and polyfluoroalkyl substances is being unwittingly unfold onto farmland, the place the chemical compounds can infiltrate our meals and water and devastate the livelihoods of farmers.
In lots of circumstances, wastewater vegetation are making these contamination points worse. Whereas industries that manufacture and use PFAS ought to bear the first duty for limiting the discharge of those poisonous compounds into our surroundings, wastewater vegetation have a twin function to play in lowering publicity. Amidst a presidential administration that introduced plans final week to roll again and delay ingesting water protections for PFAS, making use of current legal guidelines to regulate PFAS air pollution is essential. A Clear Water Act authority referred to as the Nationwide Pretreatment Program permits wastewater vegetation to curb the unfold of those chemical compounds. They’re simply not utilizing it.
At present, typical wastewater remedy processes don’t take away PFAS. As a substitute, PFAS discharged by industries to wastewater vegetation cross by the vegetation and into waterways and sewage sludge, also called biosolids. Biosolids can then be offered and utilized to land as fertilizer, permitting PFAS contamination emigrate into soil, crops, livestock, groundwater, and floor water. Making use of PFAS-laden sludge to farmland severely threatens our meals chain, to say nothing of how this observe jeopardizes farmers’ livelihoods when they’re unable to promote contaminated crops and livestock.
However wastewater vegetation have a serious alternative to regulate the inflow and unfold of PFAS chemical compounds. Pretreatment authority permits the vegetation to require native industrial clients to take away PFAS earlier than they ship wastewater to the plant for added remedy. If used extensively, this might hold excessive ranges of commercial PFAS contamination out of wastewater vegetation and, in flip, out of biosolids and waterways.
Curbing biosolids contamination wouldn’t solely cut back PFAS presence on farmland and in our meals chain, it might additionally alleviate the burden on ingesting water utilities (that are separate from wastewater vegetation) striving to offer clear water to their communities. Because it stands, many wastewater vegetation are irresponsibly discharging the PFAS they obtain from their industrial clients again into our ingesting water sources. Even worse, remedy interactions can create larger ranges of PFAS. Since most ingesting water utilities lack the remedy strategies to take away PFAS, these chemical compounds circulate by our faucets and into our glasses.
Wastewater vegetation are paid on the entrance finish to just accept industrial wastewater and on the again finish for promoting sludge, with some multistate utilities bringing in lots of of thousands and thousands of {dollars} every year. Whole U.S. wastewater remedy income amounted to $65.3 billion in 2019. The very least these public utilities can do is use their pretreatment authority to stop PFAS air pollution from reaching our ingesting water and meals.
Happily, this authority has already been confirmed. Wastewater vegetation have used the pretreatment program for many years to handle poisonous substances similar to lead, mercury, pesticides, and dioxins at minimal price. Certainly, roughly 1,600 wastewater vegetation are actively utilizing pretreatment authority to set native limits that forestall industrial pollution from passing by and interfering with their programs. This strategy is equitable and cost-effective: It appropriately places the burden of eradicating poisonous chemical compounds on the industries that revenue from their manufacture and use, somewhat than on ingesting water utilities and communities. It ought to be no totally different for PFAS.
The U.S. Environmental Safety Company agrees. In December 2022, EPA issued steerage to states that affirmed the authority of wastewater vegetation to make use of the pretreatment program to handle PFAS air pollution, albeit within the absence of federal pretreatment requirements. In observe, pretreatment authority can considerably cut back PFAS contamination. For instance, PFAS ranges coming into the Haw River from Burlington, North Carolina’s wastewater plant went from a peak of over 33,000 elements per trillion all the way down to beneath 600 elements per trillion after implementing pretreatment. (The Southern Environmental Regulation Heart, the place I work as a senior legislative affiliate, negotiated a settlement settlement between town and anxious residents, although I used to be not concerned.) Some wastewater vegetation in Michigan are additionally successfully utilizing pretreatment to curb PFAS air pollution — attaining as much as 99 p.c PFAS reductions in biosolids.
If pretreatment authority was used broadly, communities nationwide would reap near-term advantages from lowered PFAS publicity. So what’s the maintain up?
Though wastewater vegetation are required to guage and set up native limits for pollution like PFAS, many are recklessly selecting not to take action. As a substitute, they knowingly cross industrial air pollution on, leaving communities to bear the well being and monetary burdens.
Some wastewater vegetation declare they want federal requirements to behave, however the Clear Water Act affirms they will set native air pollution limits within the absence of such requirements. Different vegetation are involved that in the event that they ask their industrial clients to regulate PFAS air pollution, industries will decide up and transfer to a different city, the place they will pollute as they please. That is why it’s so necessary that wastewater vegetation maintain all industrial polluters to the identical requirements. If communities are to be equally protected against PFAS publicity, then wastewater vegetation should make use of their pretreatment authority throughout the board.
Whereas the earlier administration made momentous strides by establishing ingesting water requirements for six PFAS and designating two PFAS as hazardous substances below the Superfund regulation, it has taken a long time to get up to now, and now these rules are tied up in litigation. Codifying new federal coverage and rules is notoriously gradual, and progress has been additional delayed by the present administration’s choice to rescind ingesting water protections. Within the absence of ample federal protections in opposition to PFAS publicity, pretreatment is vital in conserving PFAS out of our ingesting water and away from our farms and meals.
As entities that pleasure themselves as public servants, wastewater vegetation have a duty to the communities they serve to scale back and management industrial PFAS contamination. The huge scope of PFAS contamination underscores the necessity to curb air pollution wherever attainable, forestall additional unfold, and reestablish duty for shielding public well being. We can not afford to attend for 1000’s of PFAS to be regulated individually, or to play whack-a-mole with every sort of PFAS-polluting trade. The time is now to make use of pretreatment authority to carry polluters accountable.
