What Is PFAS in Water and How to Avoid It
Table of Contents
Clean water is crucial to health, but recent years have focused on a group of harmful chemicals called PFAS. Discovered in everything from firefighting foam to nonstick cookware, these chemicals are being labeled as “forever chemicals.” Their presence in the environment is suspected of having a long-term effect on health and are considered a chemical weapon. However, what is precisely PFAS, and how can you minimize your exposure? This blog elucidates it for you.
What Is PFAS? (PFAS Meaning)
PFAS is dedicated to chemicals with the per- and polyfluoroalkyl composition, a collective of chemical substances that were popular during the 1940s. Famous for their resistance to heat, oil, water, and stains, PFAS are commonly incorporated into products like:
- Non-stick cookware
- Water-resistant fabric
- Fast food cooks
- Cleaning supplies
- Foam that fights fires
PFAS are often considered to be “chemicals that never decompose” because they do not break down in the natural environment or human body, this makes them a concern that persists over time.
How PFAS Ends Up in Drinking Water
PFAS (Per- and Polyfluoroalkyl substances) are environmentally persistent, which means that they don’t decompose easily and can remain in water, soil, and air for a long time. These chemicals are typically released into the drinking water sources through human activity and environmental pathways:
- Industrial Flows: Companies that produce or utilize PFAS, such as those that make non-stick cookware, water-resistant textiles, or stain-resistant carpets, often release wastewater that contains PFAS into nearby rivers or lakes. If these waters are consumed as drinking water, the water can be polluted.
- Firefighting Foam (AFFF): Aqueous-forming film, commonly utilized at airports, military bases, and fire education centers, is responsible for a large amount of PFAS pollution. These blobs travel into the ground and affect the local water supply.
- Landfill Leachate: When products that contain PFAS are deposited in landfills, rainwater can permeate through the chemicals and migrate to the groundwater as leachate. Today, municipal landfills are increasingly being considered to be a long-term source of PFAS pollution.
- Wastewater Treatment Plants: While plants that treat wastewater can eliminate many pollution types, they aren’t typically built to remove PFAS. When wastewater that contains PFAS is treated and released back into the environment, the chemicals can re-enter the system or be accumulated in sewage sludge, which can then be used as fertilizer. This will further spread the chemicals to soil and water sources, as well as to agricultural fields.
- Atmospheric Deposition: Also, PFAS can be released into the atmosphere by manufacturing facilities and deposit into soil or water via rainfall.
Once PFAS gets into a water source, it’s extremely difficult to remove without the use of advanced methods of filtration, such as reverse osmosis or activated carbon. Since these compounds are typically odorless and tastingless, most people are unaware of their presence unless water is specifically examined for the presence of PFAS.
Health Risks of PFAS in Water
- Immune System Reduction
The exposure of PFAS has been demonstrated to diminish the immune system, which causes the body to have a harder time fighting infections. Studies have demonstrated that people who are exposed to PFAS have a diminished response to vaccines, including those intended for the flu and tetanus.
- Increasedesterol levels
Exposure to PFAS over time is linked to increased total cholesterol and LDL (“poor” cholesterol). This can increase the risk of heart disease over time, even in individuals who otherwise have a healthy profile.
- Hormonal imbalance
PFAS are recognized as endocrine disruptors. They can affect the production of hormones and the regulation of hormones, this may have an effect on metabolism, thyroid function, and reproductive health. This may lead to conditions like hypothyroidism or infertility.
- Increased Probability of Certain Cancers
Numerous investigations have associated PFAS with a higher probability of having kidney and testicular cancer. The carcinogenic effects are attributed to the fact that PFAS is able to build up in body tissues over time and to destroy DNA in the cells.
- Developmental effects in fetuses and infants.
pregnant women and young children are particularly susceptible to PFAS. Prenatal exposure can result in low birth weight, developmental issues, and potential problems with learning or behavior later on. Also, PFAS can be transferred from mother to child via breast milk.
- Body’s long-term accumulation of energy
Many times, PFAS are referred to as “forever chemicals,” because they don’t decompose easily and can remain in the human body for a long time. Even a small amount of exposure to the substance can lead to health risks over time because of their long-term nature.
How to Test for PFAS in Your Water
To determine if your water is polluted:
Use home-based test kits for the PFAS or have a sample sent to a qualified laboratory.
Check your local Consumer Reports or water quality reports from the municipality.
Some states, including California and the EPA, have placed advisory limits on PFAS in drinking water (e.g., below 4 parts per trillion for PFOA and PFOS).
How to Avoid PFAS Exposure
There are several effective ways to reduce PFAS exposure from water:
- Install a reverse osmosis (RO) water filter, which is one of the most effective methods for PFAS removal.
- Choose water filters certified by NSF/ANSI 473for PFAS reduction.
- Avoid consumer products with PFAS such as stain-resistant textiles, certain nonstick pans, and microwave popcorn bags.
- Stay informed by monitoring local water quality reportsand news alerts.
Best Water Filters for PFAS Removal
To reduce the amount of PFAS in your water consumption, choosing the proper water filter is essential. Not all filters are effective at removing these chemicals that are considered “forever,” so here are the greatest filter types and what to seek out for:
- OsmosisBased Reverse Osmosis Systems
Reverse osmosis (RO) systems are commonly considered the most effective way to remove PFAS. These systems employ a semipermeable membrane that has small pores (typically 0.0001 microns) that block the passage of harmful substances, including lead, arsenic, and nitrates.
- Removezes up to 95-99% of PFAS.
- Perfect for families that have a high degree of contamination with PFAS.
- Frequent in undersink systems, whole-house units, or countertop models.
PUREPLUS 800 GPD Tankless Reverse Osmosis System has a five-step process that effectively purges up to 99.99% of pollutants, including TDS, lead, cadmium, sodium, and other radioactive substances, as well as PFAS, PFOA, and so on. This guarantees the safety of your water consumption an provides you with a sense of peace.
- Activated Carbon Filters
Granular activated carbon (GAC) or carbon blocks can reduce the effectiveness of PFAS, but only if they are:
- Specifically designed and evaluated for PFAS.
- NSF/ANSI approved, particularly under NSF P473 for the reduction of PFAs.
- Maintained and replaced on a regular basis to avoid the breakthrough of pollutants.
- These filters are typically located in: Under sink water filter systems, Refrigerator filters, Shower filters, and countertop units.
PUREPLRE PRO series refrigerator filters are NSF/ANSI 473 certified and can remove 98.15% of PFOA and 98.32% of PFOS.
- Pitcher Filters
While pitchers are typically less effective, some models are designed to reduce the presence of PFAS.
Conclusion
PFAS are a group of chemical compounds that are concealed in the water supply. Their widespread prevalence, environmental persistence, and health hazards make it essential for consumers to understand and take steps towards prevention. Start by testing your water’s quality, choosing the appropriate filter solution, and decreasing your reliance on products that contain PFAS. Clean, safe water is a privilege, and with a bit of knowledge, it’s a fact that is within reach.
