Understanding the Water Quality Concerns in Shirlington

PFAS-free drinking water Shirlington, VA is becoming a priority for homeowners as awareness grows about these persistent chemicals in our water supply. Here's what you need to know about accessing clean water in your neighborhood:
- Arlington County's tap water currently meets all EPA standards - The Washington Aqueduct has tested for PFAS and reported results below EPA-standard detection levels
- New EPA regulations take effect in 2029 - Maximum Contaminant Levels (MCLs) were set for six PFAS compounds in April 2024, with water systems required to comply within five years
- Your water comes from the Potomac River - Shirlington receives its drinking water from regional treatment facilities, with treatment occurring before it reaches your tap
- Home filtration systems offer immediate protection - Reverse osmosis, granular activated carbon (GAC), and ion exchange systems can effectively remove PFAS at the point of use
- Professional testing is available - State-certified private laboratories can test your individual water supply if you want to verify PFAS levels in your home
While Arlington County's municipal water supply meets current federal safety standards, many Shirlington residents are taking proactive steps to ensure their drinking water is as pure as possible. PFAS, often called "forever chemicals," are man-made substances that have been used in consumer products since the 1940s and can enter water sources through industrial discharges and wastewater. These chemicals persist in the environment and can bioaccumulate in the body over time, making prevention the best approach.
The good news is that you have options. Whether you're looking for a simple faucet filter or a comprehensive whole-house system, multiple solutions exist to remove PFAS from your drinking water. The challenge is understanding which approach makes sense for your home, your budget, and your family's specific needs.

I'm Amanda Casteel, and through my work with Cherry Blossom Plumbing, I've helped countless Northern Virginia families steer water quality concerns, including the growing awareness around PFAS-free drinking water Shirlington, VA. One myth I'm passionate about debunking is the assumption that county water is filtered—in reality, it's treated with chemicals like chlorine, and if you don't have a filter, you are the filter.
Understanding Shirlington's Tap Water: Sources and Official Reports
When we talk about PFAS-free drinking water Shirlington, VA, first understand where our water comes from and how it's managed. Shirlington, like much of Arlington County, relies on a robust regional water system that draws from surface water sources.
Where Shirlington's Water Comes From
Our drinking water in Shirlington originates primarily from the Potomac River. This raw water is then treated by large regional water treatment facilities that serve Arlington County, Washington D.C., and nearby communities.
Arlington County purchases its treated water either directly or through regional partners for specific pressure zones, such as the Willston Pressure Zone. These treatment plants work diligently to ensure the water meets stringent quality standards before it even reaches our municipal distribution system. The process typically involves coagulation, sedimentation, filtration, and disinfection to remove impurities and harmful microorganisms.
Current Water Quality and PFAS Levels
Arlington County is committed to providing its residents with safe and reliable drinking water. The county's drinking water consistently meets all federal Environmental Protection Agency (EPA) and Virginia Department of Health (VDH) safety standards. This compliance is a testament to the continuous testing and advanced procedures employed by the regional treatment facilities and Arlington County's Water, Sewer, Streets Bureau.
Regarding PFAS, the regional water providers have proactively tested for these chemicals. Their results have consistently shown levels below EPA-standard detection levels. This means that, under current regulations, the water supplied to Shirlington is considered safe from PFAS contamination. Arlington County regularly publishes Water Quality Reports that residents can review to stay informed about their water quality. These annual "Consumer Confidence Reports" are a requirement of the Safe Drinking Water Act.
It's also worth noting the EPA's Unregulated Contaminant Monitoring Rule (UCMR 5), which requires water systems to collect data for 30 chemical contaminants, including 29 PFAS chemicals, between 2023 and 2025. This monitoring helps the EPA gather more information on emerging contaminants to inform future regulations. As our water providers, Arlington County and its partners are actively participating in these monitoring efforts. We can find more details about Arlington County's stance and testing protocols on their About PFAS - Arlington County page.
Why Prioritize PFAS-Free Drinking Water in Shirlington, VA?
The term PFAS has become a common topic of conversation, and for good reason. PFAS, or per- and polyfluoroalkyl substances, are a group of over 6,000 man-made chemicals that have been used extensively since the 1940s. They are found in a wide array of consumer products, from non-stick cookware and water-repellent fabrics to stain-resistant carpets and firefighting foams.
The concern stems from their unique chemical structure, which makes them incredibly stable and resistant to breakdown in the environment and in our bodies. This persistence has earned them the moniker "forever chemicals." They can enter our lakes, rivers, and groundwater through industrial discharges and wastewater, eventually making their way into drinking water sources.
Even if current levels in Shirlington's municipal water are below detection limits or regulatory standards, many residents choose to prioritize PFAS-free drinking water Shirlington, VA due to the potential health implications and the chemicals' bioaccumulative nature. The importance of protecting vulnerable populations, such as pregnant women, infants, and those with compromised immune systems, further underscores this proactive approach. For more comprehensive information, the EPA’s PFAS Information page and the Center for Disease Control (CDC) offer valuable resources.
The Health Risks Associated with PFAS Exposure
Exposure to liftd levels of certain PFAS can lead to a range of adverse health outcomes. While research is ongoing, studies have linked PFAS exposure to:
- Immune System Effects: Weakened immune response to vaccines and increased susceptibility to infections.
- Developmental Effects: Lower birth weight, developmental delays, and effects on behavior in children.
- Increased Cancer Risk: Higher risk of kidney, testicular, and prostate cancers.
- Endocrine Disruption: Interference with natural hormones, potentially affecting thyroid function and reproductive health.
- Other Health Issues: High cholesterol, liver damage, and increased risk of high blood pressure in pregnant women.
These potential risks highlight why many homeowners in Shirlington are choosing to take extra precautions to ensure their drinking water is as free of these contaminants as possible. Understanding the health implications empowers us to make informed decisions about our home's water quality. The Final PFAS National Primary Drinking Water Regulation provides further details on the health effects considered by the EPA.
Understanding the New EPA Regulations
A significant development in the quest for cleaner water occurred on April 10, 2024, when the EPA released its final regulations for PFAS in drinking water for six PFAS compounds. These new regulations establish legally enforceable Maximum Contaminant Levels (MCLs) for:
- PFOA (Perfluorooctanoic acid) at 4 parts per trillion (ppt)
- PFOS (Perfluorooctanesulfonic acid) at 4 ppt
- PFNA (Perfluorononanoic acid) at 10 ppt
- PFHxS (Perfluorohexanesulfonic acid) at 10 ppt
- HFPO-DA (GenX Chemicals) at 10 ppt
Additionally, the EPA set a Hazard Index (HI) for mixtures of PFNA, PFHxS, HFPO-DA, and PFBS (Perfluorobutanesulfonic acid). This means that water systems must not only meet individual MCLs but also ensure that the combined levels of certain PFAS do not pose a health risk.
Public water systems across the country, including those serving Shirlington, are required to comply with these new standards by 2029. This five-year window allows utilities time to implement necessary monitoring, testing, and treatment upgrades. While Arlington County's water currently tests below EPA-standard detection levels, these new, stricter MCLs represent a significant shift in water quality regulation and underscore the long-term commitment to providing PFAS-free drinking water Shirlington, VA.
A Homeowner's Guide to PFAS Water Solutions
While our public water systems are working to meet new regulatory standards, many homeowners in Shirlington are looking for immediate solutions to ensure their drinking water is free from PFAS. The good news is that there are several effective options available, ranging from simple short-term fixes to comprehensive permanent installations. For a general overview, you can explore our Home Water Filtration Guide and our Drinking Water Filtration Northern VA Complete Guide.
Short-Term Solutions for Improved Drinking Water
For those seeking immediate improvement to their drinking water quality or as a temporary measure, several convenient options can help reduce PFAS:
- Water Filter Pitchers: These are perhaps the simplest and most accessible option. They typically use granular activated carbon (GAC) to filter water as it's poured. While effective for small quantities, they require regular filter replacements and don't treat all the water used in your home.
- Faucet-Mounted Filters: These attach directly to your kitchen faucet, providing filtered water on demand. They're more convenient than pitchers but are limited to a single tap and also require periodic filter changes.
- Point-of-Use Filtration: This category includes both pitcher and faucet filters, but can also encompass under-sink systems that are easier to install than whole-house solutions. These systems treat water at the specific tap where it's used for drinking and cooking.
It's important to consider environmental factors when choosing alternatives to tap water. While bottled water is an option, it carries a substantial ecological impact due to plastic production and transportation. Home filtration solutions offer a more sustainable and cost-effective approach to achieving PFAS-free drinking water Shirlington, VA.
Permanent Solutions for PFAS-Free Drinking Water in Shirlington, VA
For comprehensive and long-term protection against PFAS, we recommend exploring more robust filtration systems. These solutions offer peace of mind by treating a larger volume of water and often require less frequent maintenance than their short-term counterparts.
- Reverse Osmosis (RO) Systems: Often installed under the kitchen sink, RO systems are highly effective at removing a wide range of contaminants, including PFAS. They work by forcing water through a semi-permeable membrane that traps impurities. While they produce a small amount of wastewater, the purity of the drinking water they deliver is exceptional. You can learn more about this technology in our Reverse Osmosis PFAS Removal Arlington Guide.
- Whole-House Filtration Systems: These systems are installed at the main water line entry point to your home, treating all the water that flows through your pipes. This ensures that water used for showering, bathing, and laundry is also PFAS-free, in addition to drinking water. Whole-house systems often incorporate multiple stages of filtration, including specialized media for PFAS removal.
- Granular Activated Carbon (GAC) Filters: GAC is a highly porous material that effectively adsorbs PFAS compounds, trapping them within its structure. Many point-of-use and whole-house systems use GAC as a primary stage for PFAS removal.
- Ion Exchange Resins: These specialized resins can effectively capture PFAS molecules through an electrical charge, making them a powerful component in advanced filtration systems designed for PFAS removal.
Choosing the right system depends on your specific needs and the extent of protection you desire. Our team can help you steer these options to find the best PFAS Removal System Arlington VA Guide for your Shirlington home.
How to Verify Your Home's Need for PFAS-Free Drinking Water in Shirlington, VA
While Arlington County's municipal water generally meets high standards, individual homes can sometimes have unique circumstances that affect water quality. Factors like plumbing materials, age of pipes, and specific activities in your immediate vicinity can all play a role. If you're concerned about the presence of PFAS in your home's tap water, individual water testing is the most reliable way to get answers.
Arlington County does not provide individual water testing for residents. For those who wish to have their water tested, the state of Virginia provides resources for finding a certified laboratory. These labs have the specialized equipment and expertise to accurately detect and measure PFAS compounds in your water sample.
Once you receive your test results, understanding them can sometimes be complex. Our team can help you interpret these findings and provide expert recommendations based on the specific levels of PFAS (or other contaminants) detected. This personalized approach ensures that any filtration solution you implement is custom to your home's actual needs, providing you with true PFAS-free drinking water Shirlington, VA.
