Analyst testing for PFAS in river

Much like the chemicals themselves, PFAS (per- and polyfluoroalkyl substances) continue to be a never-ending regulatory nightmare for agencies and states that wish to ban or limit the use of these substances. Known as “forever chemicals” due to their persistent nature in the environment, PFAS pose serious health risks, including cancer, liver disease, and fetal complications. These substances are found in a wide range of consumer products, from food packaging to firefighting foams, making their regulation a critical concern for water treatment professionals and public health advocates alike.

A notable case involved the Environmental Protection Agency’s (EPA) attempt to ban plastic containers manufactured by Houston-based Inhance, which were found to be contaminated with PFOA, a toxic PFAS compound. Despite the EPA’s December prohibition, the conservative fifth circuit court of appeals overturned the ban, citing that the EPA could not regulate the containers under the statute it used. The court’s decision highlighted the challenges in regulating existing industrial processes as “new” when they’ve been in use for decades. This ruling underscores the complexities of implementing PFAS regulations and the legal interpretations that can stall protective measures.

In Colorado, efforts to strengthen PFAS legislation by 2028 have been met with enthusiasm from environmental litigators and concern for public health. Senate Bill 24-081 aims to extend the ban on class B firefighting foam to other PFAS-containing products, reflecting the growing awareness of PFAS as a major public health threat. Environmental Litigation Group associate attorney Yahn Olson highlighted the difficulty of filtering PFAS from groundwater, emphasizing the chemicals’ association with severe health conditions. This legislative push in Colorado is part of a broader move towards stringent PFAS limits, with the EPA considering setting the threshold at 4 parts per trillion, signaling a shift towards recognizing any PFAS exposure as potentially harmful.

On a positive note, 3M, a Minnesota-based chemical manufacturer, has agreed to begin payments this summer to many U.S. public drinking water systems as part of a multi-billion-dollar settlement over PFAS contamination. This settlement, approved by the U.S. District Court in Charleston, South Carolina, signifies a significant step towards addressing PFAS contamination in drinking water. The payouts, ranging from $10.5 billion to $12.5 billion through 2036, reflect the company’s commitment to exit all PFAS manufacturing by the end of 2025. This move by 3M could serve as a precedent for other manufacturers, encouraging more comprehensive solutions to the PFAS challenge.

These developments illustrate the multifaceted approach states are taking to regulate PFAS, from legal battles to legislative reforms and settlements. Despite the challenges, the persistence of regulators, litigators, and lawmakers in addressing PFAS contamination highlights a collective effort to mitigate the environmental and health impacts of these hazardous chemicals.

The old trope of “One man’s trash is another man’s treasure” is usually reserved for things like antique furniture on the side of the road or perhaps an old Marantz record player at an estate sale. However invaluable treasure is lurking in a substance long considered to be a nuisance among oil and gas producers. Recent research spearheaded by Dr. Hamidreza Samouei at Texas A&M University has brought into focus an unexpected resource in wastewater management — the potential to mine valuable minerals and metals from produced water, the wastewater brought to the surface along with oil and gas during drilling which often contains dissolved minerals, salts, and other chemicals. This revelation could reshape our approach to water treatment and resource recovery, presenting both opportunities and challenges for the industry. 

Produced water, often seen as a relatively useless and dangerous waste byproduct in oil and gas operations, is rich in minerals and elements. Samouei’s research, highlighted in the Society of Petroleum Engineers’ Journal of Petroleum Technology, reveals that produced water contains nearly every element in the periodic table, including critical minerals like lithium, rubidium, cesium, and gallium, vital for advancing technology industries. More common minerals like sodium and potassium are also abundant, offering lucrative prospects for recovery and use in various industries. 

The primary challenge in tapping into this resource is the cost of treating vast volumes of produced water, which is traditionally viewed as waste and disposed of through subsurface injections. The global annual volume of produced water exceeds 240 billion barrels, with Texas alone accounting for a significant portion. The perception of produced water as a waste product, rather than a resource, poses a significant barrier to exploring its potential. 

Samouei proposes a novel approach using CO2 desalination to mine these minerals. This groundbreaking technique involves a series of filtration methods, including ultrafiltration, nanofiltration, and reverse osmosis, to extract valuable minerals in stages before treating the water for other uses. This process not only offers an environmentally friendly solution to deal with produced water but also turns it into a source of revenue. 

Despite the potential, significant research and development are needed to make this process commercially viable. Currently, government and private funding for mineral recovery is focused on more traditional sources, like the sea floor or even asteroids. Dr. Samouei’s research aims to redirect this focus closer to home, highlighting the economic and environmental benefits of mining produced water. 

Transforming the oil and gas industry’s view of produced water from a waste product to a valuable resource requires a shift in perception and investment. Dr. Samouei envisions a future where produced water serves as a key player in the industry’s mining operations, providing essential minerals for various sectors and contributing positively to environmental sustainability. 

The potential of mining minerals from produced water offers a dual benefit — addressing the environmental challenge of wastewater management while unlocking a new source of valuable minerals. As research progresses and perceptions shift, this approach could revolutionize the way we view and utilize produced water. For water treatment professionals, this presents an exciting frontier, one that promises not only to tackle waste management challenges but also to contribute to a circular economy, where every drop of water and its hidden minerals are optimally used.
