Whole House Filters: Safeguarding Against PFAS Contamination

Even though you may not be able to smell or taste them, PFAS chemicals, commonly referred to as “forever chemicals”, are insidiously permeating the water that we consume every day. These substances are both pervasive and hazardous, underscoring the importance for consumers to remain vigilant regarding their presence and potential impact on health.

Since their inception in the 1950s, these chemicals have been integrated into a multitude of products, including firefighting foam, fast food wrappers, non-stick cookware, and stain-resistant clothing. The very qualities that render PFAS advantageous in manufacturing—such as their remarkable durability—also contribute to significant environmental challenges due to their ability to resist degradation. Once these chemicals infiltrate our ecosystem, they can persist for decades, accumulating in soil, water, and even within the human body, thereby increasing the risks associated with prolonged exposure.

Essential Insights into PFAS: Understanding the Implications of “Forever Chemicals”

Recently, Seqwater, the authority tasked with managing the drinking water supply in South East Queensland, has confirmed the detection of trace amounts of PFAS in both raw and treated water across the region. Although these levels remain low and comply with national safety standards, their rising prevalence is concerning, especially as they are increasingly identified in various catchment areas. For a more comprehensive understanding, you can explore Seqwater’s dedicated PFAS resources.

What Are the Pathways for PFAS Contaminating Our Drinking Water?

PFAS are not deliberately 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. Following rainfall, these chemicals can wash off surfaces like roads, roofs, and soil, subsequently 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 struggle to eliminate them entirely.

While the risks associated with these contaminants are currently perceived as low, numerous households in Queensland are justifiably taking precautionary measures, particularly families with young children, individuals with compromised immune systems, or those relying on rainwater tanks. In these circumstances, the implementation of whole-house water filtration systems becomes vital for ensuring peace of mind and safeguarding health.

Can Standard Water Filters Effectively Eliminate PFAS Contaminants?

In summary, most standard water filters are ineffective at removing PFAS from our water supply.

Typical filtration systems such as pitcher jugs, tap-mounted units, and basic under-sink systems are mainly designed to enhance taste, reduce chlorine levels, and capture sediment. However, when it comes to effectively addressing PFAS contaminants, these systems do not meet the necessary standards for thorough elimination.

To successfully eradicate these persistent chemicals, a more advanced approach is essential. Effective removal generally involves:

• Extended contact carbon block filtration techniques
• Anion exchange resins, or
• Reverse osmosis — advanced technologies that are not typically found in standard, off-the-shelf filters.

This raises serious concerns for households that utilise plumbed-in refrigerators, where the filtered water may appear clean yet is not specifically treated for PFAS. Most tap filters or refrigerator filter cartridges do not incorporate the necessary filtration processes or contact time required to significantly reduce PFAS levels.

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

This is where whole-house filtration systems, such as those provided by Creek to Coast Plumbing, become crucially significant.

These advanced systems treat every drop of incoming water before it reaches any tap, appliance, or plumbing fixture, including your refrigerator, thereby ensuring comprehensive protection.

Creek to Coast Plumbing installs Puretec premium-grade filtration systems that are equipped with:

• Carbon block filters designed for extended contact time — essential for effective PFAS reduction
• pH correction filters to stabilise acidic rainwater
• UV disinfection to eliminate harmful bacteria, viruses, and parasites
• Optional reverse osmosis integration for enhanced filtration at kitchen taps, if desired

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

Why Should You Choose Whole House Filtration Systems?

While a single under-sink filter might protect your kitchen tap, PFAS can still infiltrate your home through multiple outlets including bathroom taps, showers, garden hoses, and washing machines. Whole-house systems provide comprehensive protection across all outlets, which include:

• Drinking and cooking water
• Water for bathing and brushing
• Water for laundry
• Water for pets and garden use

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 of professionals.

Do Whole House Filtration Systems Truly Make a Difference?

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

• An additional barrier against chemical intrusion
• A consistent line of defence, regardless of public infrastructure
• Enhanced taste and odour, along with peace of mind
• Support for individuals with allergies or sensitivities to contaminants

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

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

Rainwater in Queensland may contain:

• Animal waste from roof catchments
• Airborne chemicals from industrial activities or bushfire zones
• Low pH water that can corrode pipes and release heavy metals into your water supply
• Tannins resulting from decomposing vegetation

This highlights the critical necessity 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.

How Can You Verify If Your Filter Effectively Addresses PFAS?

If your existing filtration system does not specifically mention PFAS reduction, it is likely inadequate for addressing this serious issue.

To confirm that your system is capable of tackling the problem, look for filters that include:

• NSF/ANSI 53 or 58 certification specifically for PFAS filtration
• Activated carbon filters designed for high contact time
• Reverse osmosis or hybrid systems rated for PFAS contaminants
• Professional installation to prevent pressure drops or bypass issues
