WQ.26/2026
WRITTEN QUESTION TO THE MINISTER FOR THE ENVIRONMENT BY DEPUTY I. GARDINER OF ST. HELIER NORTH
QUESTION SUBMITTED ON MONDAY 9th FEBRUARY 2026 ANSWER TO BE TABLED ON MONDAY 16th FEBRUARY 2026
Question
"Will the Minister advise –
- whether he is aware of any PFAS (per- and polyfluoroalkyl substances) treatment options currently being considered by Jersey Water in order to meet the 4 ng/l (4 nanograms per litre) maximum concentration proposed within the Draft Water Law (Jersey) Amendment Regulations 202-;
- if so, the indicative lead times associated with the design, procurement and installation of any such options; and
- whether, based on current information, compliance with the proposed 4 ng/l regulatory limit could potentially be achieved earlier than 1st January 2031?"
Answer
I am aware that Jersey Water is actively considering a range of potential treatment options to address PFAS limits in water quality. At this stage, no single treatment solution has been finalised. The assessment of options involves detailed technical evaluation, including suitability for Jersey's water sources, operational complexity, cost, waste handling implications and long-term effectiveness. As a result, indicative lead times for the design, procurement and installation of any specific treatment option are still being assessed. These timescales will depend on the option or combination of options ultimately selected, as well as the need for design development, procurement processes, construction, commissioning and regulatory assurance.
Progress will continue to be kept under review as further technical work is completed.
