Brofiscin Quarry

Brofiscin Quarry, Groes Faen is a disused limestone quarry in Groes-faen, near Llantrisant in South Wales. It was used for about seven years for the dumping of toxic waste including polychlorinated biphenyls (PCBs) and was capped in 2011. Some 72 000m³ / 80 000 tonnes of material was dumped here. Prior to its remediation, ''The Guardian'' described the site as "one of the most contaminated places in Britain." The level of pollution is such that it featured in an international conference discussing remediation of contaminated land. These events were described by ''The Ecologist'' magazine as "one of the biggest environmental crimes to have occurred in the UK". and the key witness at an Environmental Agency inquiry on 2006 ended up needing to live under police protection. The company using this disposal site also used the nearby Maendy Quarry.

Pollution

Brofiscin 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.Staff, Wales Online. 17 Oct, 201

The legislative frameworks prior to 1972 were not designed to deal with hazardous waste and were inadequate. This meant that the local planning department was ill-equipped when a request for planning permission was made in the late 1960's and consent was given. The Poisonous Waste Act 1972 was implemented due to other far smaller occurrences of dumping at other places in the UK.

Remediation and costs

In 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:

In 2011 Environment Agency Wales and the Rhondda Cynon Taf council announced that they had decided to place an engineered cap over the waste mass in the quarry and stated that the cost would be £1.5 million; previous estimates discussed in the media had been as high as £100 million, which Environment Agency Wales had dismissed. The site was cleared of vegetation and engineering work began in October 2011, and was completed in 2012.

On 14 July 2015, it was reported that Monsanto, BP, and Veolia had agreed to pay to contribute to the cleanup of the site, although they continue to deny liability.

The clean-up is incomplete containment, with a chemical smell still evident in boundary ditch and strong concerns remaining about neighbouring field. It has erroneously also been called Brofiscyn Quarry in an attempt to obfuscate its history.

Geology

It has been designated a Site of Special Scientific Interest due to the exposed Early Carboniferous geological formations on the site.
