Brofiscin Quarry, Groes Faen

Brofiscin Quarry, Groes Faen is a disused limestone quarry in Groes-faen, near Llantrisant in South Wales. It has been designated a Site of Special Scientific Interest due to the exposed Early Carboniferous geological formations on the site. It was used for about seven years for dumping of toxic waste including PCBs and was capped in 2011.PollutionBrofiscin Quarry is privately owned, and was leased to waste contractors for use as a landfill, as is common with spent quarries. It was used as a waste site from about 1965 to 1972 and accepted waste from BP, Veolia, and Monsanto. A 2005 report by Environmental Agency Wales found that the quarry contained up to 75 toxic substances, including heavy metals, Agent Orange, and polychlorinated biphenyls (PCBs). Prior to its remediation, The Guardian described the site as "one of the most contaminated places in Britain."Remediation and costsIn February 2011 The Ecologist and The Guardian reported that Monsanto had agreed to help with the costs of remediation, but did not accept responsibility for the pollution. A webpage at the Environmental Agency site put up at around that time states: "We have completed our extensive enquiries to identify those we consider should be held responsible under the contaminated land laws and be held liable for the cost of remediating Brofiscin Quarry. We are at an advanced stage in our consultations with BP, Veolia and Monsanto to provide them with the opportunity to help remediate the land on a voluntary basis. We expect to make further progress on this matter in the next few months. If this approach is unsuccessful, we have the power to carry out the work needed ourselves and recover our costs. The three companies have been identified under the legislation as inheriting the liabilities of companies who were associated with depositing wastes at the quarry."
