What are PFAS Chemicals?

PFAS chemicals are a large group of manufacturing chemical compounds, including PFOS and PFOA, used in a variety of products. These chemicals have strong carbon-fluorine bonds that don’t degrade in the environment.

This is why they’re also referred to as “forever” chemicals; once released into the environment, these compounds can stick around for a long time. Common products which contain or may contain PFAs include cookware, carpets, firefighting foams, creams, and cosmetics.

According to research from the Environmental Working Group, over 200 million Americans are exposed to dangerous PFA levels in their water sourced from over 40,000 municipal or industrial areas in the United States. It’s clear that these persistent contaminants need to be monitored in order to protect public health.

Types of PFAs

When it comes to per- and poly-fluorinated chemicals (PFAS), our drinking water could contain any one of the 9000+ types. Of these, some of the more well-known ones are Perfluorobutane sulfonate (PFBS), perfluorohexane Sulfonate, perfluorodecanoic acid (PFDA), Perfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonate (PFOS), Perfluorobutyrate (PFBA), and Polytetrafluoroethylene.

Each chemical has different properties that may affect our health in various ways if present at high levels. That is why it’s important to know more about these types of PFAS so that you can be more informed when it comes to deciding what type of filter or means to drink your water.

Do I Need a Water Filter That Removes PFAS Chemicals?

Do I need a water filter that removes PFAS chemicals? The simple answer is yes. There has been a great deal of information on the dangers posed by PFAs in our drinking water, and it’s highly likely that your personal drinking water supply has been contaminated with this chemical at some level.

The EPA hasn’t established a limit for this chemical in water, so your local supplier may not need to take any action.

The EPA recommends a maximum level of 70 parts per trillion of PFOA and PFOS, which some states have adopted as their standard. But, in comparison, the Environmental Working Group recommends setting a health guideline of 1 part ppt instead.

Just to be sure, you can also test your own water with a private laboratory and get accurate results. Given the serious health threat posed by PFAs chemicals, it is essential to remove even trace amounts from your tap water.

Installing a reliable drinking water filter is the safest way to protect you against these dangerous chemicals and help maintain your overall good health.

How Does PFAS Get Into Drinking Water?

When it comes to understanding how PFAs get into our drinking water, one needs to look at their sources of origin. Unfortunately, these toxic chemicals have been imported into the US from other countries since 2006 when an agreement between the EPA and eight major manufacturing companies was signed.

In addition, PFAs are long-lasting, making them difficult to remove from the environment despite the fact that attempts to phase them out started a while ago.

One way these toxins enter our drinking water is by seeping through soils or being carried by rainwater into surface or groundwater sources. The unfortunate reality is that standard methods of water treatment do not remove these forever chemicals, which means they remain in our water supplies and are subsequently sent to our homes as part of drinking water.

Why are PFAS Chemicals Dangerous to Our Health?

PFAs are chemicals that can be found in some drinking water sources, and they are dangerous to our health. According to the EPA, there are many possible health risks associated with PFAs exposure, such as developmental delays in children, fertility problems, increased risk of cancer, interference with hormones in the body, impact on the immune system’s response to infections, and increased risk of obesity and high cholesterol levels.

All of these risks come from long-term exposure to these chemicals and make it clear why it is so important for us to take steps to reduce our exposure.

The bottom line is that PFAs pose serious dangers if ingested and should not be taken lightly. It is essential that we do our part to safeguard our drinking water by making sure that sources are regularly tested for contamination and taking steps to minimize our contact with potential sources of PFAs pollution in order to protect ourselves and future generations.

How to Test for PFAs in Water

The best way to verify the presence of PFAs in your tap water is by buying a testing kit from a laboratory. We recommend SimpleLab Tap Score for reliable water testing results. The cost of a PFAs water test may be quite costly at around $300, but it’s worth it for the accuracy of the results.

The water testing process involves collecting samples of your drinking water, often through activated carbon cartridges which can be posted to the lab in special kits. Once you’ve sent your sample off to be tested, you should receive an in-depth report that will tell you whether there are any traces of PFAs present in your drinking water or not.

Most Common PFAS Present in Water

When it comes to contaminants present in groundwater, PFAS compounds are some of the most commonly found. Two of the most abundant and well-researched chemicals from this family are perfluorooctanoic acid (PFOA), and perfluoro octane sulfonate (PFOS).

These chemicals have been produced in large quantities over the years and are among the best-studied materials present in water.

Health Impacts of PFAS

The health impacts of exposure to PFOA and PFOS are serious and far-reaching. People exposed to these substances can experience effects including congenital disabilities, increased cholesterol levels, changes in liver functioning, high blood pressure, immune response abnormalities, pre-eclampsia in pregnant women, increased risk of obesity, infertility problems, thyroid problems, altered metabolism, reduced learning ability in children.

Moreover, the risks posed by such exposure include a higher likelihood of developing certain cancers – making this an, especially concerning environmental hazard. It is essential that we become more aware of the potential harm PFOA and PFOS can bring to human health so that we can better protect ourselves from coming into contact with it.

How Under Sink Water Filters Remove PFAS

Under sink water filter is the best way to remove PFAS, such as Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA), from your drinking water.

Granular Activated Carbon

Granular Activated Carbon (GAC) is a highly effective way of removing PFAS from water, as found by EPA researcher Thomas Peth. It’s made from sources like lignite coal, wood, and other organic materials that have a high carbon content.

With the right type of carbon, flow rate, bed depth, temperature and other contaminants in the water, GAC can remove certain PFAS with 100% effectiveness. The more GAC in the filter and the longer it stands in contact with the water – the more effective the removal is.

Under sink filters with GAC work better on long-chain PFAS like PFOS and PFOA than it does on short-chain compounds like PFBA and PFBS. Research also shows that GAC filters are more successful at removing these chemicals than carbon block filters.

Ion Exchange Resins

Ion exchange resins are incredibly useful when it comes to removing contaminants such as PFAS from water. These resins are created from a polymeric, water insoluble material with tiny beads of hydrocarbons making up the body. Depending on what needs to be treated and removed two types of ion exchange resin are available: cationic or anionic.

These resins draw in and trap the targeted contaminant within their porous structure, allowing safe passage of clean water through as they do so. PFAS particles can be successfully removed using anion exchange resins (AER), which are more costly than granular activated carbon.

In addition to AERs, a nanofiltration is also an option for treating contaminated water and achieving removal rates of up to 99%. This membrane filtration system effectively excludes materials based on size and can easily be used at home to produce smaller amounts of PFAS free drinking water.
