Whole House Filters: Safeguarding Water from PFAS Contamination

Although you cannot smell or taste them, PFAS chemicals, often referred to as “forever chemicals”, are infiltrating the water we consume on a daily basis. These substances are both insidious and pervasive, making it imperative for consumers to be informed about their presence and potential impacts on health. Understanding the ramifications of PFAS contamination is crucial for protecting yourself and your family, as these chemicals can have long-lasting effects on our ecosystem and wellbeing.

Since their introduction in the 1950s, these chemicals have been incorporated into a wide variety of products, including firefighting foam, fast food wrappers, non-stick cookware, and stain-resistant clothing. The very properties that make PFAS effective in manufacturing—such as their remarkable durability and resistance to heat and stains—are also responsible for their significant environmental challenges: they resist degradation. Once these chemicals enter the ecosystem, they can persist for years, accumulating in soil, water, and even within the human body, thereby compounding the risks associated with long-term exposure over time.

Essential Insights on PFAS: Understanding the Reality of “Forever Chemicals”

Recently, Seqwater, the authority responsible for overseeing the drinking water supply in South East Queensland, confirmed that trace amounts of PFAS have been detected in both raw and treated water throughout the area. Although these levels remain minimal and comply with national safety standards, their increasing presence is concerning, especially as they are being identified more frequently in various catchment areas. For a more comprehensive understanding of this issue, you can visit Seqwater’s dedicated PFAS resources page, which provides valuable information on the ongoing monitoring and management of these chemicals in drinking water.

What Are the Pathways Through Which PFAS Contaminate Our Drinking Water?

PFAS are not intentionally introduced during the water treatment process. Instead, they infiltrate the water supply through various external pathways, such as industrial waste, landfill runoff, fire training sites, and stormwater runoff. When it rains, these chemicals can wash off surfaces like roads, roofs, and soil, flowing into the rivers and dams that supply our water treatment facilities. Due to the resilience of these substances, even advanced water treatment technologies may not completely eliminate them, resulting in potential health risks for consumers.

While the risks associated with these contaminants are currently viewed as low, many households in Queensland are justifiably taking precautionary measures, particularly families with young children, individuals with compromised immune systems, or those who depend on rainwater tanks. In such scenarios, the adoption of whole-house water filtration systems becomes essential for peace of mind and to ensure the safety of drinking and cooking water.

Can Standard Water Filters Effectively Remove PFAS Contaminants from Your Water Supply?

In brief, most standard water filters are ineffective at removing PFAS contaminants from drinking water.

Typical filtration systems such as pitcher jugs, tap-mounted units, and basic under-sink systems are primarily designed to improve taste, reduce chlorine levels, and capture sediment. However, when it comes to addressing PFAS contaminants, these systems do not meet the necessary performance standards to ensure safety and health. Understanding the limitations of these filters is crucial for consumers seeking effective solutions.

To effectively eradicate these persistent chemicals, a more sophisticated approach is required. Proper removal generally involves:

• Extended contact carbon block filtration techniques, which enable better interaction with water
• Anion exchange resins, which can effectively capture and remove these chemicals, or
• Reverse osmosis — advanced technologies not typically featured in standard, off-the-shelf filters, providing a higher level of purification.

This raises serious concerns for households that utilise plumbed-in refrigerators, where the filtered water may appear clean but is not specifically treated for PFAS. Most tap filters or refrigerator filter cartridges lack the necessary filtration processes or contact time required to significantly lower PFAS levels, potentially exposing families to harmful chemicals.

What Role Do Whole House Filtration Systems Play in Minimising PFAS Exposure?

This is where whole-house filtration systems, such as those provided by Creek to Coast Plumbing, become critically important for ensuring safe drinking water.

These state-of-the-art systems treat every drop of incoming water before it reaches any tap, appliance, or plumbing fixture, including your refrigerator. By doing so, they provide comprehensive protection against harmful contaminants.

Creek to Coast Plumbing installs Puretec premium-grade filtration systems that incorporate:

• Carbon block filters specifically designed for extended contact time — crucial for effective PFAS reduction
• pH correction filters to stabilise acidic rainwater and prevent corrosion
• UV disinfection to eliminate harmful bacteria, viruses, and parasites that can affect health
• Optional reverse osmosis integration for additional filtration at kitchen taps, if desired, further enhancing water purity

It’s not merely about enhancing the taste of your water; it’s about protecting your entire household from harmful contaminants at the source, ensuring safer water for showers, laundry, and cooking, not just for drinking.

Why Should You Choose Comprehensive Whole House Filtration Systems?

While a single under-sink filter may safeguard your kitchen tap, PFAS can still infiltrate your home through various outlets such as bathroom taps, showers, garden hoses, and washing machines. Whole-house systems offer comprehensive protection across all outlets, providing a consistent and reliable source of clean water. This includes:

• Drinking and cooking water, ensuring safety for meal preparation
• Water for bathing and brushing, promoting better hygiene
• Water for laundry, protecting fabrics and skin
• Water for pets and garden use, safeguarding your loved ones

Puretec’s FilterWall F-Series and Hybrid-Plus systems are robust enough to ensure complete household protection, installed right at the point of entry by our skilled and licensed team, allowing you to enjoy peace of mind.

Do Whole House Filtration Systems Truly Make a Difference in PFAS Reduction?

Absolutely, especially for families concerned about cumulative exposure to contaminants. While Seqwater is actively managing water quality, implementing filtration at the home level provides:

• An added barrier against chemical intrusion, giving an extra layer of security
• A consistent line of defence, regardless of public infrastructure, ensuring safety at home
• Improved taste and odour, enhancing your overall drinking experience
• Support for individuals with allergies or sensitivities, creating a healthier living environment

Comparing Town Water vs. Rainwater: Assessing the Risks Associated with Both Supplies

Even if you are connected to a town water supply, PFAS can still permeate into your home. If you are harvesting rainwater for household use, however, your risk profile is significantly heightened due to various factors.

Rainwater in Queensland may contain:

• Animal waste from roof catchments, posing health risks
• Airborne chemicals from industrial activities or bushfire zones, affecting water quality
• Low pH water that can corrode pipes and release heavy metals into your water supply, creating additional hazards
• Tannins resulting from decomposing vegetation, potentially affecting taste and clarity

This highlights the pressing need for a whole-house system for homes relying on tank water, particularly those with children, elderly residents, or frequent visitors who may not be accustomed to untreated water. Ensuring safe and clean water is essential for health and wellbeing.

How Can You Verify If Your Filter Effectively Addresses PFAS Contamination?

If your current filtration system does not specifically mention PFAS reduction, it is likely inadequate for this purpose. Ensuring your system is capable of addressing the issue is crucial for your health.

To verify the effectiveness of your filtration system, look for filters that include:

• NSF/ANSI 53 or 58 certification, specifically for PFAS filtration, ensuring compliance with industry standards
• Activated carbon filters engineered for high contact time, promoting better filtration
• Reverse osmosis or hybrid systems rated for PFAS contaminants, providing advanced purification
• Professional installation to avoid pressure drops or bypass issues, ensuring optimal performance
