It’s every homeowner’s nightmare: You buy a home, move in, then find out there’s an abandoned gas well beneath, leaking and contaminating your property.

Think it can’t happen to you? It can. According to the Energy Resources Conservation Board in November 2012 over 150,000 abandoned wellsites dotted the Alberta landscape, making it essential that buyers do their homework.

“These nightmares happen because of gaps between what Albertans should know, could know and actually do know about their environment,” says Adam Driedzic, Staff Counsel and author of a new Environmental Law Centre publication, What Lies Beneath? Access to Environmental Information in Alberta.
