A legal limit for PFAS in Jersey's drinking water will be introduced for the first time.
Regulations have been proposed, introducing a limit of four nanograms per litre for the so-called 'forever chemicals'.
Jersey Water will be given five years to meet the new standards, but the government is stressing the water supply meets current EU and UK standards.
Environment Minister Deputy Steve Luce has lodged the regulations with the States Assembly, calling it an important step forward.
"Under the Water (Jersey) Law 1972, water quality is assessed against a series of chemical parameters to determine whether it is considered wholesome. The proposed Regulations would add PFAS to this list for the first time.
"This development follows detailed work by the Independent PFAS Scientific Advisory Panel.
"The Panel has recommended the introduction of a new limit of 4 nanograms per litre for the combined concentration of four PFAS substances in our public water supply. They have also advised that this standard should be achieved over a five‑year period."
Deputy Luce says the new statutory standard will future-prof the island's drinking supply and there is no cause for concern over the current PFAS levels in mains water.
