The Environment Agency Wales and the local authority, Rhondda Cynon Taff county borough council, have been working in partnership with the local health board, the national health service in Wales and the Food Standards Agency to ensure a co-ordinated approach to the issue at Brofiscin quarry. Monsanto, Solutia Inc.—the parent company of Solutia UK—are co-operating with the Environment Agency in their investigations under part IIa of the Environmental Protection Act 1990.
While the Environment Agency in Wales’ investigations have confirmed pollution of deep groundwater and intermittent pollution of surface waters, they have found no detectable risk to drinking supplies. It will be publishing its latest report on this matter shortly in the spring, which will bring together all monitoring results taken to date and provide an interpretation of what is happening on site.
Assessment of what appropriate remedial action is necessary is currently ongoing. Investigations into identifying the “appropriate persons” responsible for the cost of these remedial works are also still ongoing.
