The municipal water supply for Lac-Mégantic was shut down on the evening of the explosion because of a leak inside the blast zone, requiring trucks carrying drinking water, though the leak was repaired overnight and a precautionary boil-water advisory issued. The industrial park lost access to rail service in both directions as the line remained severed until December 2013. Claims to local insurers were estimated at $25 million for Intact Financial, $18 million for and $7 million for Desjardins Group. List of victims and their ages     All but 800 of the evacuated residents were allowed to return to their homes in the afternoon of the third day; all but 200 were able to return by the sixth day. At least twenty had no home to which to return. Some homes had reportedly been broken into during their vacancies, although police deny that homes were looted. Rail World's president and CEO Edward Burkhardt visited the town on July 10, 2013, and was heckled by residents. After the accident, the railway's safety record was called into question: over the previous decade the firm recorded a higher accident rate than the rest of the U.S. rail fleet, according to data from the Federal Railroad Administration. In the previous year, the railroad had 36.1 accidents per million miles travelled, in comparison to a national average of 14.6 accidents. Burkhardt's historical involvement with a 1996 derailment on the Wisconsin Central in which hazardous materials burned for over two weeks also drew renewed scrutiny. While the actual cause of the disaster was still under provincial (Sûreté du Québec) and federal (Transportation Safety Board) investigation, Burkhardt announced the railway had suspended the engineer for allegedly improperly setting the handbrakes on the rail cars. The engineer was made unavailable at the suggestion of his lawyer and MMA instructed its employees not to answer questions from police without first consulting the company's lawyers. A former colleague established an Albany-based legal defence fund for the engineer. The Sûreté du Québec raided MMA offices in Farnham on July 25 as part of a criminal investigation into the Lac-Mégantic fatalities; the Transportation Safety Board conducted its own search backed by RCMP on August 1. Raymond Lafontaine, a local contractor who lost a son, two daughters-in-law and an employee, raised concerns about the poor condition of MMA-owned track and about the increasing quantity of dangerous goods being transported through downtown areas by rail, not only in Lac-Mégantic but in cities such as Sherbrooke.
