Toxic Chemicals

Question: asked Her Majesty's Government:What assessment has been made of the quantity of polychlorinated biphenyls and dioxins and other toxic chemicals that have leached into the Cardiff aquifer from Brofiscin Quarry; whether this pollution continues; and what action is being taken to protect the water from further pollution.

Answer: The Environment Agency has not made an estimate of the quantity of contaminants that have leached into the Miskin aquifer from Brofiscin Quarry. Investigations to date have concentrated on the shallow groundwater regime beneath the quarry, and its interactions with the surface water environment. The conceptual site model report of July 2007 confirms the pollution of controlled waters from the waste mass is ongoing. The Environment Agency is currently conducting a remedial options appraisal in accordance with the relevant legislation and statutory guidance.
