CONCERNS ABOUT HEAVY METAL POLLUTION IN THE MARINE ENVIRONMENT

Following recent events, Save Our Shoreline believe that Environmental Services are not properly monitoring the waters of the South East Coast for the presence of heavy metal pollutants from the Waterfront, West of Albert and La Collette reclamation sites.

The visually evident degradation of the closest areas to La Collette and the recent high levels of human effluent which has been damaging oyster fisheries, we believe, is the tip of the iceberg. Jersey’s entire shellfish industry could be at risk.

Heavy metals such as lead, mercury and cadmium, build up in the environment over time and recent excavation work on the incinerator has opened a window onto a potential pollution pathway, revealing material which runs off into the adjacent Ramsar area. Heavy metals are invisible, odourless and toxic, and are extremely difficult to remove once they have built up in the marine environment, in filter feeders such as oysters and cockles, and ultimately into the human food chain.

Environmental Protection have stated that there is no evidence of significant pollution so far. They site test only slipper limpets, which are not filter feeders. At a recent Scrutiny Hearing, Tim Du Feu, Environmental Water Regulator, admitted that testing of heavy metals requires testing of filter feeders.

Recently, at Castle Quay raw incinerator ash was exposed to the high spring tides twice daily. Environmental Health officers have stated that they did not test the water and saw no reason to halt work, despite there being in our view a clear and serious infraction of the Water Pollution Laws and the Ospar Convention. Heavy metals in the ash would have been disturbed by excavation and liberated in solution and carried out to sea.

Even more serious is the question of the chronic pollution at La Collette, where the toxic ash is stored, and prior to 1995 was just dumped with inert waste and other waste materials such as asbestos, loose into the sea. After impaction, this mix forms the base of La Collette and tidal action is steadily leaching heavy metals from the bottom and inside voids beneath the site.

SOS believe that as Environment do not appear to be conducting any meaningful baseline studies, (and in fact did not even consider the necessity of conducting baseline studies of the marine biota in the Ramsar area prior to construction of the new incinerator) a baseline study needs to be done as an urgent priority, in order to establish current levels of heavy metals at this point in time. SOS believe that the problem will build up year on year and urgently call on the States accept that they need to explore what damage limitation is possible.
