Whole House Filters: Protecting Against PFAS Contamination

Even though you cannot smell or taste them, the presence of PFAS chemicals, commonly referred to as “forever chemicals”, is becoming increasingly prevalent in the water we consume every day. These substances are not only insidious but also remarkably persistent, making it essential for consumers to be fully aware of their existence and the potential risks they pose to health and the environment.

Since their introduction in the 1950s, these chemicals have been used in various products, including firefighting foam, fast food wrappers, non-stick cookware, and stain-resistant clothing. The very characteristics that make PFAS effective in manufacturing—like their outstanding durability and resistance to heat—are also the reasons they present significant environmental challenges: they resist degradation. Once they infiltrate the ecosystem, these chemicals can remain for years, accumulating in soil, water, and even within the human body, which can intensify the health risks linked to prolonged exposure.

Essential Insights on PFAS: Understanding the Truth Behind “Forever Chemicals”

Recently, Seqwater, the governing body responsible for managing the drinking water supply in South East Queensland, has confirmed the detection of trace amounts of PFAS in both raw and treated water throughout the region. Although these levels are currently minimal and comply with national safety standards, their rising presence is concerning, especially as they are increasingly discovered in different catchment areas. For those seeking more detailed information, you can explore Seqwater’s dedicated PFAS resources for further insights.

How Do PFAS Contaminate Our Drinking Water? Understanding the Pathways

PFAS do not enter the water treatment process intentionally; rather, they infiltrate the water supply through various external pathways, including industrial waste, landfill runoff, fire training sites, and stormwater runoff. During rainfall events, these chemicals can wash off surfaces like roads, roofs, and soil, eventually flowing into the rivers and dams that supply our water treatment facilities. Given the durability of these chemicals, even advanced water treatment technologies may not be fully capable of eliminating them, leaving a potential threat in our drinking water.

While the associated risks of these contaminants are currently deemed low, many households in Queensland are proactively taking precautionary measures, particularly families with young children, individuals with weakened immune systems, or those who depend on rainwater tanks. In these cases, the implementation of whole-house water filtration systems becomes vital for ensuring peace of mind regarding water safety.

Are Conventional Water Filters Effective in Removing PFAS Contaminants?

In summary, most standard water filters are ineffective when it comes to removing PFAS.

Common filtration systems such as pitcher jugs, tap-mounted units, and basic under-sink systems primarily aim to improve taste, diminish chlorine levels, and capture sediment. However, with regard to effectively addressing PFAS contaminants, these systems do not meet the necessary standards for adequate filtration.

To successfully eliminate these stubborn chemicals, a more advanced filtration approach is essential. Proper removal usually entails:

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

This situation raises serious concerns for households utilizing plumbed-in refrigerators, as 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.

The Importance of Whole House Filtration Systems in Minimizing PFAS Exposure

This is where whole-house filtration systems, such as those provided by Creek to Coast Plumbing, become crucial in safeguarding our health.

These state-of-the-art systems ensure that every drop of incoming water is treated before it reaches any tap, appliance, or plumbing fixture, including your refrigerator, providing comprehensive protection.

Creek to Coast Plumbing specializes in installing Puretec premium-grade filtration systems that feature:

• Carbon block filters designed to ensure extended contact time — a critical factor for effective PFAS reduction
• pH correction filters to stabilize acidic rainwater
• UV disinfection to eradicate harmful bacteria, viruses, and parasites
• Optional reverse osmosis integration for additional 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 hazardous contaminants right at the source, ensuring cleaner water for showers, laundry, and cooking—not just for drinking.

Why Opt for Whole House Filtration Systems?

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

• 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 experienced and licensed team.

Do Whole House Filtration Systems Make a Significant Impact?

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

• An additional barrier against chemical intrusion
• A consistent line of defense, irrespective of public infrastructure
• Enhanced taste and odor, along with peace of mind
• Support for individuals with allergies or sensitivities

Comparing Town Water and Rainwater: Assessing the Risks Associated with Both Sources

Even if you are connected to a town water supply, PFAS can still make their way into your home. Conversely, if you rely on rainwater for household use, your risk profile is substantially increased.

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 situation highlights the critical need for a whole-house system for homes that depend on tank water, particularly those with children, elderly residents, or frequent visitors who may not be acclimated to untreated water.

How Can You Determine if Your Filter Effectively Reduces PFAS?

If your current filtration system does not explicitly indicate PFAS reduction, it is likely inadequate for this purpose.

To confirm your system's capability to tackle PFAS contamination, seek out filters that include:

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