[5] After the closure of the clay pits the site was used until 1972 for dumping of highly toxic industrial waste, mostly from the Burmah-Castrol company at Ellesmere Port, comprising around 94000 tons of sulphuric acid mixed with tar-like hydrocarbons, 7500 tons of spent bentonite containing absorbed heavy oil, and over 1000 metal drums with unknown contents, comprising one of the largest instances of such dumping in the UK.

[5] The site, along with an adjacent tip used for dumping of chemical waste from the Monsanto works in Cefn Mawr, was purchased in 1980 from the landowners for £1 by the then local authority Clwyd County Council, as the latter was concerned about environmental contamination.

[8] A variety of plans have been put forward for decontamination, though none have yet been implemented due to the high estimated cost of the remediation work.
