Jersey Sea Foam Carries 'Forever Chemicals'

Residents and visitors in Jersey are being warned to avoid contact with sea foam accumulating on local beaches. Experts have reported that this naturally occurring foam can collect significantly higher levels of PFAS, often referred to as 'forever chemicals,' than the seawater itself.

These persistent chemicals have been associated with serious health concerns, including kidney and testicular cancer. While swimming in the sea is considered safe, the organic matter within sea foam could potentially irritate skin, cause stomach upset, or affect breathing, particularly in children and pets. Therefore, authorities advise keeping young children and animals away from thick, persistent foam.

Concerns have been raised following the Independent PFAS Scientific Advisory Panel's findings. Samples taken last summer at St Brelade's Bay and Le Grouet slipway revealed PFAS levels of 1,005 and 1,806 nanograms per litre, respectively, with no detectable levels in the adjacent seawater. Experts emphasize that this phenomenon is not unique to Jersey and can be observed on coastlines elsewhere, including the UK.

Further research is planned to explore other potential exposure routes, such as sea spray. Ministers are expected to provide a more detailed response to the report later this year, addressing the implications of these findings for public health and environmental safety.
