PFAS in Sludge: What It Means for Waste Producers and Discharge Consent Holders

PFAS contamination is no longer just a buzzword in the environmental world — it’s a developing risk for any business involved in waste, effluent, or sludge handling.

Often referred to as “forever chemicals,” PFAS compounds don’t break down in the environment. They’ve been used widely in manufacturing, packaging, cleaning products, and industrial processes for decades. And now, they’re showing up in the most inconvenient places: agricultural soils, food chains, water courses — and sludge.

At Trade Effluent Services, we’re seeing a growing concern across the waste and wastewater landscape. The Environment Agency is tightening its focus, and that means more scrutiny for producers, consent holders, and contractors alike.


Why PFAS Is Becoming Your Problem — Even If You’re Not the Source

You don’t have to handle PFAS directly to be affected. Here’s why it matters:

  • The EA is scaling up sampling — Sites that never had to test for PFAS before may be expected to do so in the near future.
  • Farmers are walking away from biosolids — Once a low-cost, sustainable route for sludge disposal, land spreading is now facing community and regulatory pushback.
  • PFAS conditions may be added to your discharge permit — Just like pH, COD, or oil and grease, expect PFAS to join the list of parameters you’re accountable for.

The kicker? PFAS can enter your stream upstream, without your knowledge — via treated water, cleaning agents, industrial residues, or packaging materials.


Who Needs to Be Paying Attention?

We’re not just talking about water companies or chemical processors. These are the businesses most at risk of PFAS exposure or regulation in 2025:

  • Food and drink manufacturers, especially those with oily, protein-rich effluent or heavy detergent use
  • Waste contractors managing septic, FOG, or sludge materials
  • Agricultural sites storing or spreading sludge from third parties
  • Any site with a trade effluent consent that discharges to sewer

What You Can Do Right Now

This doesn’t have to be a scramble. A few proactive steps can protect your site — and your reputation.

1. Review your consent and sludge documentation

Check if PFAS is mentioned. If not, ask your undertaker or EA rep what their policy is. You don’t want to be caught out by a surprise update.

2. Speak to your waste hauliers and sludge outlets

Are they already screening for PFAS? Are thresholds changing? Start the conversation now.

3. Consider basic PFAS testing

Even a one-off sample gives you a baseline. If PFAS is present, you can plan. If it’s not, you have evidence on file.

4. Audit your upstream chemical use

PFAS might be sneaking in through things like surface coatings, fluorinated cleaning agents, or even staff PPE.
