# Forever chemicals in Jersey water could cost £210m to remove

**In brief:** Jersey Water says early trial results for removing PFAS “forever chemicals” from the island’s water supply are “encouraging,” with levels reduced by around 30% at one treatment site. However, the company warns that full implementation could cost between £140 million and £210 million, and a definitive report will not be ready until the end of 2027.

## What Are PFAS and Why Do They Matter?

If you have not yet heard the term PFAS, it is time to pay attention. Per- and polyfluoroalkyl substances, known as “forever chemicals” because of how stubbornly they resist breaking down in the environment and in the human body, have been in widespread industrial use since the 1940s. The BBC reports they have been used to manufacture thousands of everyday items, from non-stick pots and pans to waterproof clothing.

The health implications are not trivial. PFAS have previously been linked to serious conditions including kidney and testicular cancer. For islanders who rely on Jersey’s water supply, the question of what is coming out of the tap is therefore rather more than an abstract environmental concern.

## Encouraging Signs, But a Long Road Ahead

Jersey Water’s chief executive, Helier Smith, has described the early results from trial tests at the company’s Augres treatment works as “certainly important and encouraging.” The BBC reports that the trials have so far reduced PFAS concentrations in water by approximately 30%. The company is testing four different removal methods across both its Augres and Handois treatment sites.

Smith was careful, however, not to get ahead of the science. The water company itself described the findings as “preliminary,” stressing that “further testing and evaluation” is needed before a long-term treatment solution can be identified. A full pilot trial, which Smith says will cost around £2 million, is expected to take 12 months to complete, with a final report due at the end of 2027.

On the question of transparency, Smith was unequivocal: “There’s clearly a public interest in PFAS and we made a promise when we started these pilot trials to be transparent and share our results on a regular basis. We want to make sure everyone understands what’s happening so we can go on that journey together with our customers.”

## The Cost: A Potential £210 Million Question

Here is where things get sobering for Jersey residents. Smith told the BBC that, in a worst-case scenario, an entirely new treatment works could be required on the island. The price tag for that outcome sits somewhere between £140 million and £210 million, a figure that will concentrate minds both at Jersey Water and, one imagines, in the corridors of Broad Street.

Smith framed the ongoing pilot trials partly as a means of narrowing down what the actual cost will be, suggesting the full-scale figure may yet prove avoidable or reducible depending on which treatment technologies prove most effective. Nevertheless, even the lower end of that estimate represents a very significant infrastructure investment for a small island community.

For context, Jersey Water serves a population of roughly 100,000 people. A bill of £140 million to £210 million, however it is ultimately financed, whether through tariffs, government support or borrowing, will have real consequences for household water bills and public finances alike. Islanders would be wise to watch the 2027 report closely.

## The NSFW Perspective

There is something almost poetic about the fact that humanity spent decades coating its frying pans in a substance that turns out to be essentially indestructible and potentially carcinogenic, and is now facing a bill of up to £210 million in Jersey alone to deal with the consequences. Progress, of a sort.

To be fair to Jersey Water, the company appears to be handling this with commendable openness. Promising transparency and actually delivering it are two different things, but publishing preliminary results, even when they are not yet conclusive, is the right instinct. Islanders deserve to know what is in their water, and they deserve to know what it will cost to fix it.

The real test will come in 2027. At that point, the island will need clear answers, clear costs and a clear plan. Given the sums potentially involved, this is not a conversation that can be left to Jersey Water alone. Government, regulators and the public will all need a seat at the table, and ideally one that was not made with PFAS.
