WThe Aberfan disaster was the catastrophic collapse of a colliery spoil tip at around 9:15 am on 21 October 1966. The tip had been created on a mountain slope above the Welsh village of Aberfan, near Merthyr Tydfil, and overlaid a natural spring. A period of heavy rain led to a build-up of water within the tip which caused it to suddenly slide downhill as a slurry, killing 116 children and 28 adults as it engulfed Pantglas Junior School and other buildings. The tip was the responsibility of the National Coal Board (NCB), and the subsequent inquiry placed the blame for the disaster on the organisation and nine named employees.
WThe Tribunal of Inquiry into the Aberfan Disaster, chaired by Lord Justice Edmund Davies, was established in 1966 to inquire into the causes of and circumstances of the Aberfan disaster. The report of the tribunal placed the blame for the disaster on the National Coal Board (NCB), naming nine of its staff as having some degree of responsibility.
WThe Armley asbestos disaster is an ongoing health issue originating in Armley, a suburb of Leeds, West Yorkshire, England. Described by Dr. Geoffrey Tweedale as a "social disaster", it involved the contamination with asbestos dust of an area consisting of around 1,000 houses in the Armley Lodge area of the city.
WThe Bawtry gasworks contamination involved land at Bawtry, South Yorkshire, England containing hazardous byproducts from the manufacture of coal gas. Remediation of the land was at public expense through the Environment Agency (EA), who then sought to recover the costs from National Grid Gas (NGG), then known as Transco, declaring it the "appropriate person" under Part IIA of the Environmental Protection Act 1990 and therefore liable on the basis that one or more of its statutory predecessors caused the contamination. NGG sought a judicial review in the High Court of Justice where Mr. Justice Forbes ruled that they were liable for the costs of the decontamination. The ruling was considered a crucial issue by NGG as, if they were deemed liable in this particular instance, then they could be found liable in a substantial number, possibly thousands, of other cases involving former gasworks.
WBeaufort's Dyke is a natural trench between Northern Ireland and Scotland within the North Channel. The dyke is 50 km long, 3.5 km wide and 200–300 m (700–1,000 ft) deep.
WThe Camelford water pollution incident involved the accidental contamination of the drinking water supply to the town of Camelford, Cornwall, in July 1988. Twenty tonnes of aluminium sulphate was inadvertently added to the water supply, raising the concentration to 3,000 times the admissible level. As the aluminium sulphate broke down it produced several tonnes of sulphuric acid which "stripped a cocktail of chemicals from the pipe networks as well as lead and copper piping in people's homes." Many people who came into contact with the contaminated water experienced a range of short-term health effects, and many victims suffered long-term effects whose implications remained unclear as of 2012. There has been no rigorous examination or monitoring of the health of the victims since the incident, which is Britain's worst mass poisoning event. Inquests on people who died many years later found very high levels of aluminium in the brain. Dame Barbara Clayton led a Royal Commission on Environmental Pollution enquiry into the incident.
WThe Corby toxic waste case was a court case decided by The Hon. Mr. Justice Akenhead at the High Court of Justice, London, on 29 July 2009 in the case of Corby Group Litigation v. Corby Borough Council [2009] EWHC 1944 (TCC). The judge found Corby Borough Council liable in negligence, public nuisance and a breach of statutory duty for its reclamation of a Corby Steelworks in the town of Corby, Northamptonshire, between 1985 and 1997. The landmark decision was historically significant as the first in the world to establish a link between atmospheric toxic waste and birth defects - all previous cases have involved water pollution - and held implications for other council reclamation programs and the methods of conducting reclamation in England and Wales.
WThe Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected the British capital in early December 1952. A period of unusually cold weather combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed.
WThe Great Stink was an event in Central London in July and August 1858 during which the hot weather exacerbated the smell of untreated human waste and industrial effluent that was present on the banks of the River Thames. The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. The miasma from the effluent was thought to transmit contagious diseases, and three outbreaks of cholera before the Great Stink were blamed on the ongoing problems with the river.
WThe Sea Empress oil spill occurred at the entrance to the Milford Haven Waterway in Pembrokeshire, Wales on 15 February 1996. The Sea Empress was en route to the Texaco oil refinery near Pembroke when she became grounded on mid-channel rocks at St. Ann's Head. Over the course of a week, she spilt 72,000 tons of crude oil into the sea. The spill occurred within the Pembrokeshire Coast National Park – one of Europe's most important and sensitive wildlife and marine conservation areas. It was Britain's third largest oil spillage and the twelfth largest in the world at the time.
WThe Windscale fire of 10 October 1957 was the worst nuclear accident in Great Britain's history, and one of the worst in the world, ranked in severity at level 5 out of a possible 7 on the International Nuclear Event Scale. The fire took place in Unit 1 of the two-pile Windscale facility on the northwest coast of England in Cumberland. The two graphite-moderated reactors, referred to at the time as "piles", had been built as part of the British post-war atomic bomb project. Windscale Pile No. 1 was operational in October 1950 followed by Pile No. 2 in June 1951.
