PFAS In Your Hays Water

The issue with PFAS (per- and polyfluoroalkyl substances) and similar contaminants is multifaceted and has been exacerbated by a lack of public awareness and understanding until relatively recently. These compounds were not widely known or comprehended by the general population, and even within scientific and regulatory communities, their potential risks were not fully appreciated for a significant portion of the 20th century.

Adding to the complexity of the problem is the pervasive presence of PFAS in our environment. Over decades of industrial use and disposal, PFAS have become nearly ubiquitous. They have infiltrated our air, water sources, soil, and food chain. The persistent nature of PFAS means that once they are released into the environment, they do not break down easily and can persist for extended periods. This persistence allows them to accumulate in the environment and build up in the tissues of living organisms, including humans.

Certain areas have a higher propensity for PFAS-contaminated water. For example, if you live near an airport or a firefighter training facility where many of these chemicals have historically been used, there’s a good chance they’re still found in relatively high concentrations. Areas around manufacturing centers also commonly have elevated levels of PFAS, since they were used in the production of carpet, food packaging and production, and many other consumer goods.

There is no way for you prevent PFAS contamination in the environment, but you can make sure the water you’re drinking is PFAS free. If there is good news regarding PFAS water contamination, it’s that they can be treated and removed from water with the right filtration. For example, several methods, like carbon filtration, ion exchange, and reverse osmosis water treatment effectively remove PFAS from water.

PFOA, the most notable substance of the PFAS family, was found to be a part of the manufacturing process of Teflon. The EPA sued DuPont in 2005 for failing to report a health risk to both humans and the environment. The company paid a $10.25 million settlement.

Because of PFOA and PFAS strong molecular structure, they take much longer to break down naturally than other organic chemicals.

Until 2002, PFOA were integral in producing goods which qualities repel dirt, grease, water and stains.

These contaminants can be found in the manufacturing process of a variety of products, including non-stick cookware, carpet-care liquids, treated apparel, upholstery or textiles, sealants, dental floss, floor wax and non-woven medical garments. Though PFTE non-stick cookware was proven to have PFOA levels, a recent study found levels that ranged from undetectable to 4.3 parts per billion, and it is not currently considered a major pathway for PFOA.

Just last year, United Nations experts recommended banning PFOA globally at the Stockholm Convention on Persistent Organic Pollutants. Will the United States follow suit based on recent outbreaks in Texas and Michigan.

According to a study from 2002-2005, people who lived in the PFOA-contaminated area around DuPont’s Washington Works facility were found to have higher levels of PFOA in their blood from drinking water. People that drank more tap water, ate locally grown fruits and vegetables, or ate local meat, were all associated with having higher PFOA levels.

Residents who used carbon filter systems had lower PFOA levels.” Studies have found that using carbon-activated filters can reduce PFOA by up to 60%.

The EPA has issued a “Health Advisory” for PFOA and PFAS, but this does not amount to any actual forced federal regulations on municipalities to control and monitor them.

The EPA has established health advisory levels at 70 parts per trillion as of 2020.

How Much Is 70 Parts Per Trillion?

To compare 70 parts per trillion, think of a drop of ink in a backyard pool. According to its website, “EPA’s health advisory level for PFOA and PFOS offers a margin of protection for all Americans throughout their life from adverse health effects resulting from exposure to PFOA and PFAS in drinking water.”

A few of the adverse health conditions a lifetime of exposure can lead to are develop- mental effects in children, kidney and testicular cancer and immunodeficiency disorders.
