The CDC to Conduct Exposure Assessments for PFAS at 10 Sites

Understanding Pathways to Exposure

Per- and Polyfluoroalkyl Substances (PFAS), which include PFOS and PFOA, are everywhere. For such a long name, there are even longer-lasting ramifications for what this substance leaves behind.

PFAS are persistent, bio-accumulative substances that can be found in many things— from cleaning products, leather, textiles, non-stick cookware, pesticides and more.

For those just tuning in, PFAS are persistent, bio-accumulative substances that can be found in many things— from cleaning products, leather, textiles, non-stick cookware, pesticides and more. They’re all around us — in fact, they’ve been detected in the blood of every United States resident. According to the Centers for Disease Control and Prevention (CDC), most people are exposed to them by drinking or eating PFAS-contaminated water or food.

What’s the big concern?

The list of health issues that exposure to PFAS has been linked to is exhausting. It includes an increased risk in thyroid disease, asthma diagnosis, cholesterol diagnoses, and an increased risk of cancer. Additionally, it’s been linked to a decreased fertility rate, lower infant birth rates, a decrease in how well the body responds to vaccines and can change or damage liver function.

Reduce PFAS with a whole house filter

While the Environmental Protection Agency (EPA) has been hard at work implementing programs and policies on the Federal level, with goals ranging from phasing out commercial PFA use, to reducing emissions, the CDC has been working to scientifically study and better identify pathways to contamination.

And now, the CDC has just landed a huge opportunity.

The history behind PFAS studies

PFAS have been in heavy use since the 1950s — from nonstick cookware to water-repellant clothing to firefighting foams—and it’s no wonder corporations can’t seem to quit the habit.

And since PFAS are bio-accumulative, the EPA therein has worked hard to implement policies that help incentivize and curb the commercial use of PFAS in the United States.

Starting with their previous goals in the PFOA Stewardship Program, they had simple policies that were two-pronged:

  • Reduce PFOA emissions and product content by 95 percent from the 2000 baseline recordings by no later than 2010.
  • Eliminate PFOAs from emissions and products by 2015.

But since PFAS tend to stick around for a long time, that doesn’t exactly answer the call for what needs to be done about the PFAS that are already here. So, the EPA laid out the following action items at a recent summit:

  • Evaluate maximum contaminant levels
  • Work to have the Federal Government label PFOA and PFOS as “hazardous substances”
  • Create cleanup recommendations for contaminated areas
  • Create toxicity values to better measure acceptable dosages

In short, they seek to characterize and identify scientific methods to measure risk and contamination, spread awareness about PFAS to the general United States population, and work to contain the contaminant.

The CDC and the Agency for Toxic Substances and Disease Registry (ATSDR) on the other hand have long been working together to study and better understand this toxic contaminant and give tools to the public to better safeguard themselves in their own homes.

The CDC/ATSDR will track PFAS exposure pathways

How do you better spread knowledge and awareness about a toxic substance? Rigorous scientific study and research, of course.

That’s why the CDC, along with the Agency for Toxic Substances and Disease Registry (ATSDR), is announcing their new combined initiative to profile 10 military sites across the United States and study them for toxicity levels.

The study sites will be near National Guard bases in the following states:

  • Pennsylvania
  • West Virginia
  • Colorado
  • Alaska
  • Massachusetts
  • Texas
  • Delaware
  • New York
  • Washington

The primary goal of this study will be to “identify where exposure is coming from, how much people are exposed to and how long they have been exposed”.

This is different from a health study in that it won’t examine the health effects of those routinely exposed to PFAS in their everyday environment, but will work to identify contamination levels.

Starting later this year and staggering their research through 2020, this exposure assessment will help scientists to better understand the pathways to contaminant exposure as well, helping the rest of us to avoid PFAS in the future.

Securing better healthcare for veterans and beyond

As anyone knows, the best way to combat a contaminant is by understanding what you’re up against. That’s how the CDC was able to secure funding for this study in its 2018-2019 fiscal year budget: if we can better understand PFAS at contaminated military bases, we can provide better healthcare for veterans, our armed forces, and beyond.

According to the CDC website, for those wanting to participate in the study, the rewards are pretty high.

“ATSDR expects to establish cooperative agreements with up to six recipients, with awards ranging from $500,000 to $3 million per recipient. Applications must be submitted electronically no later than 5:00 p.m., ET, on May 30, 2019. Information on how to apply is at www.grants.gov.”

Combating PFAS in your home

As we’ve previously mentioned, PFAS are everywhere, particularly in your drinking water.Optim-Instagram_4

If you’re looking to cut PFAS out of your water and give your family some peace of mind, you can invest in water filtration methods that filter PFAS throughout your entire home.

Start by looking for either the IAPMO or NSF seal. That will tell you whether or not the product has been tested and certified by an independent, third-party entity like the NSF that develops standards for clean water, food and consumer products, or IAPMO, which independently tests and certifies to rigorous NSF standards.

Aquasana’s OptimH2O Whole House Filter, for example, is certified to remove more than 98% of PFAS from your water throughout your entire house — from your shower to your kitchen tap — and is tested and certified by IAPMO to NSF standards.

Additionally, Aquasana’s Under Sink 3-Stage Max Flow is NSF tested and certified for the reduction of PFOA/PFOS — and was the first Under Sink filter of its kind to do this.

Even though the CDC and the EPA are working hard to understand the pathways to PFAS contamination thanks to rigorous scientific study, you don’t have to wait for the inevitable bad news to come to you. You can have water filtration act as your first line of defense, and start filtering PFAS from the water in your own home before it reaches your kitchen sink. Because healthy water means a happy home.
