The Aberfan Disaster Memorial Fund (ADMF) was set up on the day of the disaster. It received nearly 88,000 contributions, totalling £1.75 million. The remaining tips were removed only after a lengthy fight by Aberfan residents, against resistance from the NCB and the government on the grounds of cost. Clearing was paid for by a government grant and a forced contribution of £150,000 taken from the memorial fund. In 1997 the British government paid back the £150,000 to the ADMF, and in 2007 the Welsh Government donated £1.5 million to the fund and £500,000 to the Aberfan Education Charity as recompense for the money wrongly taken. Many of the village's residents suffered medical problems, and half the survivors have experienced post-traumatic stress disorder at some time in their lives.
