When Deb Bjork, an avid hiker, moved to Fort Collins, Colorado, she appeared ahead to the scenic views and recent mountain air. As a substitute, she has discovered herself residing in a spot the American Lung Affiliation not too long ago ranked 18th among the many US cities with the unhealthiest air to breathe. (Denver, an hour’s drive south, ranked seventh due to the area’s excessive ozone ranges.)
“You’re taking a hike within the foothills and also you look down and also you see the brown cloud, however I had no concept how a lot was coming from fracking,” says Bjork, who was recognized with bronchial asthma in her 40s after she beat down. in Colorado.
However there’s one other hazard lurking on the market. Along with soiled air, Colorado’s oil and gasoline business additionally exposes residents to a different sort of air pollution—solely this one you possibly can’t see. To frack for oil and gasoline, the business pumps chemical cocktails into the bottom to interrupt up shale rock, doubtlessly contaminating groundwater. These cocktails could embody a category of chemical compounds known as perfluoroalkyl and polyfluoroalkyl substances (PFAS for brief), publicity to which has been linked to a variety of well being issues, together with most cancers, thyroid illness, developmental issues and reproductive hurt. They’re known as “endlessly chemical compounds” as a result of they’re extraordinarily proof against degradation within the setting they usually bioaccumulate in our our bodies. In reality, the Facilities for Illness Management and Prevention says that PFAS may be discovered within the blood of just about each particular person in the US.
The presence of PFAS in our lives stems from the usage of these chemical compounds in a variety of client merchandise present in our meals, clothes and houses – particularly in merchandise that make our items water, stain and grease resistant. Nonetheless, the oil and gasoline business’s use of PFAS just isn’t so nicely documented.
“The best way fracking destroys water is already actually scary, and PFAS is only one extra method it is taking place,” stated Kate Christensen, who leads the fracking effort for Colorado’s Chapter of 350, a worldwide local weather group dedicated to cease the usage of fossil fuels. The state has roughly 52,000 oil and gasoline wells, about 22,000 of that are in Weld County, simply east of Fort Collins. And plans for hundreds of latest ones are presently underway.
Bjork, a retired psychologist who volunteers with a number of native and nationwide environmental teams, can be involved about PFAS, notably for the well being of her 5 grandchildren who stay domestically. “However I doubt most individuals even learn about it,” she says of the fracking-PFAS connection. “Most individuals do not even know there’s poor air high quality right here. They don’t know.”
Fracking with poisonous chemical compounds endlessly
Information that oil and gasoline corporations have been utilizing PFAS in fracking operations first emerged in a July 2021 report by Physicians for Social Duty (PSR). Its authors discovered proof in US Environmental Safety Company (EPA) information that PFAS had been utilized in greater than 1,200 wells in six states between 2012 and 2020. The information, obtained by PSR beneath a Freedom of Data Act request, confirmed that regardless of regulators’ issues about three new PFAS chemical compounds that doubtlessly degrade into PFOA (a very dangerous sort of PFAS), the EPA permitted them in 2010 for oil and gasoline drilling. After additional analysis, PSR found that variations of the chemical compounds had been injected into hundreds of wells.
The 2021 report didn’t embody Colorado, however a year-long Colorado-focused investigation by PSR’s Dusty Horwitt and Barbara Gottlieb quickly adopted. The findings recommended that PFAS publicity was doubtless amongst many Coloradans, particularly those that stay close to oil and gasoline wells. Horwitt and Gottlieb’s evaluation of business information — listed on FracFocus, the official repository for Colorado oil and gasoline chemical compounds — decided that PFAS has been used within the state’s wells since a minimum of 2008 and located proof of its use in 10 counties, predominantly in Weld and Garfield .
“Oil and gasoline operations are notably unhealthy locations to make use of PFAS—or any sort of hazardous chemical—as a result of there are such a lot of completely different contamination pathways,” Horwitt says. PFAS not solely find yourself in our water, but additionally in our air because of the methane burning strategies utilized by business. “It is too dangerous.”
One other examine by Public Workers for Environmental Duty (PEER) present in October 2021 that Colorado could have extra PFAS-contaminated websites than another state, with 86 % of these 21,000 websites involving the oil and gasoline business.
Along with above-ground leaks and spills at nicely websites, PFAS can leach into the groundwater via cracks inside wells. Contamination can even happen earlier than the precise fracking begins, when corporations drill straight into groundwater, or throughout or after the method via the injection or improper disposal of wastewater tainted with PFAS or different poisonous chemical compounds. The refining course of is one other supply of air pollution, as seen not too long ago within the waters close to Suncor, Colorado’s solely oil refinery, situated north of Denver. A examine ready for Earthjustice final April traced a lot of the PFAS present in Sand Creek and the South Platte River to Suncor’s discharges. The waterways not solely present consuming water to a number of massive municipalities downstream, however the South Platte can be vital for agricultural irrigation.
Lifting the veil of secrecy
Whereas Horwitt says the fracking business is thought to make use of PFAS in its operations, he cannot say for certain how a lot or how typically it has occurred. That is due to Colorado’s chemical exemptions, which permit oil and gasoline corporations to withhold details about the substances they use in fracking, together with PFAS, by claiming the formulation are commerce secrets and techniques. The PSR discovered that between 2011 and 2021, oil and gasoline operators in Colorado injected practically 414 million kilos of thriller chemical compounds into 12,000 wells in 31 of Colorado’s counties. “If even a small fraction of this weight was PFAS, that fraction may pose vital well being and environmental dangers,” the report’s authors wrote.
However to the aid of advocates, beginning on the finish of July 2023 (on account of a legislation that Gov. Jared Polis signed final June), these exemptions are over. A brand new coverage would require chemical producers to certify that their merchandise utilized in downhole oil and gasoline manufacturing don’t comprise PFAS and to record all chemical compounds they use in these operations — info that have to be listed and made public obtainable on the Colorado Oil & Gasoline Conservation Fee (COGCC) web site.
One other new legislation, additionally signed by Polis in June, goes after PFAS extra straight. Much like states like California, it bans the pointless use of perpetual chemical compounds in client merchandise similar to cookware, cosmetics, meals packaging and carpets. And in a primary for the nation, this legislation additionally bans the usage of PFAS in fluids used to extract oil and gasoline.
Ean Thomas Tafoya, who leads GreenLatinos’ Colorado work, credit the work of activists like Liz Rosenbaum and 11-year-old Madhvi Chittoor for the progress the state is making on PFAS, and says public well being efforts are reaching extra Coloradans than ever earlier than. “COVID created extra alternatives for distant witnessing, and that has been a sport changer for neighborhood participation, particularly in the event you stay in rural Colorado,” says Tafoya. “I can say straight that improved democratic entry performed a serious position within the success we have had in regulating PFAS and different toxins.”
And that is excellent news, as a result of even with the promise of those new legal guidelines, there’s nonetheless quite a lot of work to be achieved. Sonya Lunder, senior toxics coverage adviser for the Sierra Membership, says the legal guidelines characterize “a robust connection between toxics and fracking conversations, however I do not assume anybody looks like we have utterly solved each issues.”
Lunder says we’d like extra complete modifications. “Discovering out that tens of millions of kilos a yr of essentially the most dangerous chemical compounds we all know of in commerce might be used within the oil and gasoline business and no one would know, simply exposes the brokenness of the system,” she says. “Our vulnerability to this can occur many times till there’s some fundamental, rudimentary overview of how issues are made and the way the business works in the US. We’re very removed from that time for the time being.”
Along with the brand new legal guidelines, Horwitt says the state ought to go a step additional and conduct exams close to oil and gasoline wells for the presence of PFAS in groundwater, floor water and soil to evaluate the extent of present contamination ranges. He additionally encourages involved residents to contact their elected officers to request such a take a look at.
Colorado may paved the way
The federal authorities’s response to the PFAS disaster has not been sufficient. At present, it largely regulates chemical compounds, together with hundreds of very comparable PFASs, one by one — and every evaluation can take a long time. For instance, the EPA simply proposed designating two PFAS chemical compounds, PFOA and PFOS, as hazardous beneath the Superfund Act in August. The company has taken the same chemical-by-chemical method to consuming water, and the federal authorities has additionally been sluggish to cease the pointless use of PFAS.
That is the place states can step in to assist fill the hole, explains Avinash Kar, a senior lawyer who directs NRDC’s Wholesome Meals and Communities Program. “There is a ton of motion on the state stage to take care of PFAS, whereas the federal stuff has been a little bit of a drag.” For instance, strikes in California and New York to ban the whole class of PFAS in client merchandise, similar to textiles and meals packaging, may change the nationwide market given the dimensions of the states’ markets.
Colorado advocates equally hope their state’s dedication to curbing PFAS, notably within the oil and gasoline business, is usually a mannequin for different states. “Till we are able to shut off PFAS, till we are able to determine the way to get them out of the water, we now have an enormous duty in Colorado,” Tafoya says. “We’re a headwater state and tens of millions of individuals get their water from us, so we’re an excellent place to essentially draw the road.”
