The WQA (Water Quality Association) describes PFAS as emerging contaminants of great concern in drinking water. In this article, we will break down four areas to help you understand PFAS contaminants.

  1. What is the definition of PFAS?
  2. Where do these contaminants come from?
  3. Why should you be concerned?
  4. What are the best mitigation/removal technologies

To get started, let’s provide a definition to help form a reference for these contaminants. PFAS would be more accurately stated as PFA’s. They are an overall category for PFOA and PFOS compounds. These are the two most common compounds being found and researched today. The American Cancer Society provides these definitions:

PFAS – lab-made chemicals known as perfluoroalkyl and polyfluoroalkyl substances (Category)
PFOA – Perfluorooctanoic Acid (Compound) –
PFOS – Perfluorooctane Sulfonate (Compound)

PFOA and PFOS are a manufactured perfluorochemical and a byproduct in producing fluoropolymers. Perfluorochemicals (PFCs) are a group of chemicals used to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water.

If you can pronounce these accurately, then your science background is well formed. From here on, we’ll try to keep this in simple terms.

After breaking down the acronyms, people often wonder what specific ways these chemicals were used. The NTP (National Toxicology Program – US Dept. of Human Health and Services) states that these chemicals were used to keep food from sticking to cookware, make stain-resistant sofas and carpets, waterproof clothing and mattresses, and may also be used in some food packaging, as well as in some fire fighting materials. Because they help reduce friction, they are also used in a variety of other industries including aerospace, automotive, building and construction, and electronics.

You probably recognize several of these types of products and may have used some of them yourself years ago. Unfortunately, these chemicals were not disposed of properly by their manufacturers decades ago and have now found their way into the groundwater supplies around our nation. These chemicals have been given the name “Forever Chemicals” because they last forever and do not break down in the environment. In some studies, they have been given a greater than 50,000 year expected life span. There is continuing research towards remediation. This research poses the questions; how do we remove PFAS out of the environment, and then how do we destroy them?

As you might think, with long-lasting chemicals in CA groundwater, there could be some health concerns. The health effects of PFAS on humans will vary depending on the research studies, but all are considered serious. 

Current peer-reviewed scientific studies have shown that exposure to certain levels of PFAS may lead to:

  • Reproductive effects such as decreased fertility or increased high blood pressure in pregnant women.
  • Developmental effects or delays in children, including low birth weight, accelerated puberty, bone variations, or behavioral changes.
  • Increased risk of some cancers, including prostate, kidney, and testicular cancers.
  • Reduced ability of the body’s immune system to fight infections, including reduced vaccine response.
  • Interference with the body’s natural hormones.
  • Increased cholesterol levels and/or risk of obesity.

On the ATSDR website (Agency for Toxic Substances and Disease Registry), they make it a point to explain “not all of these studies involved the same groups of people, the same type of exposure, or the same PFAS.” As an emerging contaminant, the physical effects from exposure are something that need further research. 

Two technologies have been tested and recognized to remove up to 98% of PFAS from drinking water. Both the WQA and a Purdue University study identified reverse osmosis and activated carbon as reliable solutions.

A reverse osmosis system will include a membrane along with other filters in its system. The membrane is the key to the removal of most PFAS. Other filtration systems, such as shell carbon filters, microfiltration, or ultrafiltration, will not remove PFAS effectively. A reverse osmosis system purifies your water versus filtering it. The membrane is a pressure-driven technology with a small pore size that allows very few contaminants to pass through. Reverse osmosis is a single-point system usually accessed at one faucet by the kitchen sink. It is not intended for whole-home purification.

For whole-home removal, Activated Carbon is another removal solution. Activated Carbon is a little more involved because its effectiveness depends on the exposure time of water to the proper level of carbon media for effective removal. This is not a do-it-yourself project. Contact us today to provide you with the expertise for proper removal of PFAS contaminants. 

A third technology is being researched with an Ion Exchange Resin. An Ion Exchange Resin is what you will find in your water softener. However, this new resin is designed differently to remove PFAS. Hopefully, more will come from this research soon.

With all this information you may be wondering “What should I do for my water in Pleasanton and the surrounding areas?”

Do your research and learn as much as you can. Whether you’re on municipal water or well water, our team at AAA Water Systems, Inc can help. We understand the water chemistry in Northern California & Central Valley, the proper treatment, and maintenance. Fill out the form below or call us today at 925-686-6788.

Sam is the ultimate professional and just a great person overall! There’s not enough words that I can express to capture how well of a job he’s done for my home and family.In short, Sam had to work with myself and the builders of my home to address a knocking sound that had nothing to do my water filtration system (But was involved just to make sure everything was free and clear from the work performed during the water filtration install by AAA). In addressing all of these variables, Sam just displayed the ultimate professionalism, while also having to drive out really far to my home for each visit (3-4 times).Today the issues were fully addressed/fixed. Thanks to Sam’s patience, diligence and just being a good hearted person, we were able to get to the bottom of everything.As it relates to my whole house water filtration and RO system, it is the best thing that has happened for my household. There’s been no issues and works as described by our excellent sales guys Al.Overall, AAA Water Systems is a great company that values excellent customer service (It’s truly a lost value/art these days). They go above and beyond to not only make sure that their customers are taken care of, but that their workmanship reflects the same quality.From Al (Salesperson) , to the installer, to Sam (Manager) and the owner Tony, they exemplify and exude all the qualities that you’d want in a company.Thanks again Sam! You are a true gentleman and GEM!

Dylan's exceptional support and patience in explaining the current local water issue, including the presence of cancer-causing contaminants, and emphasizing the critical importance of clean water made a profound impact on my family and me. We were deeply convinced that we decided to make an investment right away. Dylan expertly tailored a solution that perfectly matched our budget while effectively addressing the health risks posed by these contaminants.We also received visit from their management team to ensure a flawless installation process, which exceeded my expectations. This level of extended service was nothing short of extraordinary, and the installation proceeded seamlessly.When I had questions about consuming RO (Reverse Osmosis) water to eliminate these cancer-causing contaminants, they addressed them promptly and thoroughly. AAA doesn't merely sell water filtration systems; they deliver top-tier service while safeguarding the health and well-being of our family.Moreover, the added benefit of drinking water with peace of mind and experiencing the delightful taste of water that rivals bottled water has been a pleasant surprise. We had no idea water could taste this good, making every sip as enjoyable as bottled water.My only 'issue' now is that regular water doesn't feel or taste the same anymore. This experience has turned me into a water snob – I can't help but feel a tad paranoid. I am now accustomed to the highest standard of filtered water at home that it's hard to trust anything else!

For months I have been looking for a water filtration system. I was able to schedule an appointment with their sales Rep Dylan. He was on time and answered all of my questions on their system. They have a unique product that does not require a drain or an electrical outlet. The company also does their own installation as well which is very convenient.The installation process took 5.5 hours. Gerardo was very punctual and did a great job. He wore shoe covers inside the house during the installation. The tank outside had certain HOA requirements and he was able to complete the installation. Overall the service was great and I can already taste the difference in our water.

He is also available over the phone later on and patiently answered all the questions I asked.They listened to my requirements and suggested the correct products as per my usage. Once the products are purchased, the same day I received a call from technician and they scheduled a date for installation.I'm very satisfied with AAA water systems and also recommend using their products and service.

We are very pleased with our new water system. Thank you Oscar and AAA Water System.I also would like to thank Al Skender, our service advisor from AAA Kinetico. He was very professional and took the time to test and verify our water condition. He was highly knowledgeable and answered all the questions I had. Once the installation was done, he came back to follow up to check on the water pressure to make sure everything runs properly. We highly recommend Al Skender and this company. Thank you so much!

Oscar was excellent and made sure to do the job properly and professionally. He was also knowledgeable and helped answer any questions related to the RO or Softner.I would like to give a big Thank You to Seth Stephenson who came to my home and introduced me to Kinetico by AAA Water Systems. A few weeks prior to calling Seth I had already committed to ECOWATER systems from COSTCO however since their installation was pushed to late June I had some time for more research.Thank goodness I did as my neighbor mentioned about the Kinetico Softner and RO from AAA Water Systems. My neighbor mentioned that they had their Kinetico softner and RO for 10 years and were still loving it. My main concerns were reliability, warranty, and the cost of maintenance. When Seth came and did his presentation he was very honest with me and knowledgeable. He was not trying to make a quick sell or steer me away from ECOWATER by bad mouthing them. However everything he explained seemed to have more PROs Vs. CONs when comparing it to the ECOWATER Systems.I was really impressed with Seths professionalism and how he eased all of my concerns with the maintenance and reliability of both the Kinetico Softner & RO. Since the install was complete I had a few minor issues but Seth was there for me checking up and making sure everything was being taken care of. He would call me regularly and even off work hours to handle the issues by placing calls and sending the right team members to fix the issues. With his dedicated service and how he treated me I would gladly recommend him and Kinetico by AAA Water Systems to all my family and friends.Seth really proved that he values his relationship with his customers and wants AAA waters to always live up to it’s high standards of service and reliability. Thank you again Seth as I look forward to continuing our business relationship for many more years.

As a former employee of AAA Water, I know a lot of the ins and outs of the company and I can say with confidence that the owner Tony is a good man who is passionate about Kinetico because they have products worthy of that passion.Each year I have my RO service, the technicians are kind and professional. I don’t know how I lived before my K5. So much so that my RO service gets its own line item in our budget because it’s a family necessity.If you are thinking about a water softener or reverse osmosis, Kinetico is the ONLY way to go, AAA Water is the exclusive Kinetico dealer AND a great company. It’s a win win!A former employee who still loves their previous boss and the product they sell? That’s testament enough right?!?
