Date: Jul 11, 2025
From 1 July 2025, the game changed. Australia’s long-awaited PFAS crackdown is now officially in force, bringing with it strict new limits for drinking water and a sweeping ban on the import, manufacture, and use of key PFAS chemicals.
This isn’t just another regulatory update, but a major turning point for public health, environmental safety, and industry accountability.
If your business works with water, chemicals, coatings, or contaminated sites, PFAS compliance is no longer optional – it’s urgent.
So what exactly has changed? And how can you stay ahead of the curve?
Here’s what you need to know and how Leeder Analytical is helping organisations meet the moment with confidence.
In short
As of 1 July 2025, Australia has banned key PFAS chemicals (including PFOS, PFOA, and PFHxS) and introduced ultra-low drinking water limits. These “forever chemicals” are now tightly regulated across industries.
What’s next
Check your SDSs, flag banned CAS numbers, and review your water systems. If you haven’t already, it’s time to schedule high-sensitivity PFAS testing to stay compliant and identify hidden risks.
Read on to find out why PFAS are so hard to remove and what actually works when it comes to staying compliant.
What Are PFAS and Why Are They Banned?
PFAS (per- and polyfluoroalkyl substances) are a family of synthetic chemicals best known for their ability to repel water, oil, stains, and heat. Their uses span:
- Firefighting foams (especially AFFF)
- Industrial coatings and non-stick applications
- Paints, sealants, and lubricants
- Cleaning agents, antifoams, and more
But their chemical durability comes at a price.
PFAS don’t break down easily in the environment, earning them the nickname “forever chemicals.” Over time, they accumulate in soil, water, animals, and even human bloodstreams.
And PFAS aren’t just a regulatory headache – they’re a serious, well-documented threat to human health and the environment.
Over decades of global research, scientists have uncovered a growing list of health concerns linked to long-term PFAS exposure, even at very low levels.
Here’s what the science is telling us:
- Increased Cancer Risks: Several PFAS compounds, including PFOA and PFOS, have been classified as possible human carcinogens. Long-term exposure has been associated with higher rates of kidney, testicular, and other cancers.
- Thyroid and Immune System Disruption: PFAS can interfere with normal hormone function, leading to thyroid disorders.
They’ve also been shown to suppress immune responses, including reduced vaccine effectiveness and increased susceptibility to illness. - Developmental Issues in Children: Prenatal and early-life exposure to PFAS has been linked to low birth weight, altered growth, learning delays, and behavioural problems, making it especially concerning for pregnant women and young families.
- Environmental Persistence and Contamination: PFAS don’t break down naturally. They build up in soil, groundwater, wildlife, and the human body over time.
Some have even been detected in rainwater, Arctic ice, and remote ecosystems, underscoring their global reach.
Because of these risks, governments around the world are taking action. From the EU to the US and now Australia, PFAS bans, import restrictions, and ultra-low water guideline values are being introduced to limit further exposure.
What Changed on 1 July 2025?
Australia’s PFAS regulatory landscape now includes two major shifts:
1. National Ban on Key PFAS Chemicals
From July 1, it is now illegal to manufacture, import, export, or use the following:
- PFOS (CAS 763-23-1)
- PFOA (CAS 335-67-1)
- PFHxS (CAS 355-46-4)
These restrictions apply across industries, from Defence and aviation to construction, mining, and industrial cleaning.
Even if your business doesn’t intentionally use PFAS, they could still be lurking in everyday products, quietly putting you at risk of non-compliance.
PFAS often hide in:
- Antifoaming agents
- Industrial cleaning chemicals
- Powder coatings and resins
- Graffiti-resistant or marine-grade paints
- Aerosol and spray formulations
Don’t assume you’re in the clear. Now’s the time to dig into your Safety Data Sheets (SDS), check for banned CAS numbers, and work with your suppliers to phase out any non-compliant materials.
2. New PFAS Drinking Water Guidelines
Australia has updated its health-based guideline values (HBGVs) for PFAS in drinking water, reflecting stricter international benchmarks and new carcinogenicity classifications.
The new maximum values are:
| Compound | New Max Value |
|---|---|
| PFOA | 200 ng/L (0.2 μg/L) |
| PFOS | 8 ng/L (0.008 μg/L) |
| PFHxS | 30 ng/L (0.03 μg/L) |
| PFBS | 1000 ng/L (1 μg/L) |
These ultra-low thresholds demand high-sensitivity testing that many standard labs simply can’t achieve.
Why Conventional Treatment Won’t Cut It
Still relying on traditional water treatment methods? You’re not alone, but when it comes to PFAS, they simply aren’t enough.
The go-to techniques used across Australia (coagulation, sedimentation, and chlorination) are great for removing many contaminants. But PFAS? They barely touch them.
These “forever chemicals” are engineered to resist breakdown, making them remarkably persistent even in advanced water systems.
To effectively reduce PFAS to the new ultra-low guideline levels, you need specialised technologies built for the job:
- Granular Activated Carbon (GAC): Absorbs PFAS molecules from contaminated water but requires regular media replacement to remain effective.
- Anion Exchange Resins: Swap PFAS compounds for safe ions, offering high efficiency for shorter-chain PFAS where GAC may fall short.
- Reverse Osmosis (RO): A pressure-based filtration process that can physically block PFAS molecules from passing through – ideal for high-risk sites and drinking water systems.
But even the best treatment system is only as good as the PFAS analysis behind it. Without detailed insight into the type and concentration of compounds present, even advanced systems can fall short.
What Should You Do Next?
If your organisation handles water, chemicals, coatings, or industrial processes, the time to act is now. With the regulations already in effect, being unprepared isn’t just risky – it could result in legal, environmental, and reputational consequences.
Here’s a practical 5-step plan to help you stay compliant and future-proof:
1. Review Your Chemical Inventories and Safety Data Sheets (SDSs)
Start with the basics. Conduct a full audit of all chemicals used across your operations, including cleaning products, coatings, antifoaming agents, and any imported goods.
PFAS often hide in unexpected places, so check the fine print in your SDSs and technical data sheets for any red flags.
2. Check for Banned PFAS CAS Numbers
Don’t just rely on brand names or product descriptions. The banned substances now include:
- PFOS (CAS 763-23-1)
- PFOA (CAS 335-67-1)
- PFHxS (CAS 355-46-4)
Search your SDSs and supplier documents for these exact CAS numbers and flag any products for immediate review or replacement.
3. Assess Your Water Systems Against New Guideline Values
If you’re managing a water utility, treatment plant, or industrial discharge system, compare your PFAS levels against the new health-based guideline values (as low as 8 ng/L for PFOS). These limits require high-precision data, so older test results may no longer be relevant.
4. Schedule PFAS Testing with an Accredited Laboratory
To comply with new drinking water and environmental thresholds, you need ultra-sensitive, high-resolution testing. Choose a NATA-accredited lab like Leeder Analytical that can detect both known and emerging PFAS compounds using advanced Orbitrap LC-MS technology.
5. Plan for Treatment Upgrades or Supplier Changes
If PFAS are present above regulatory levels, it’s time to act. This may involve:
- Upgrading treatment systems with GAC, RO, or anion exchange
- Sourcing PFAS-free chemical alternatives
- Working with environmental consultants to manage site-specific risks
Early action reduces disruption, protects your reputation, and helps demonstrate regulatory due diligence.
