520	|a"In the mid-1970's, an 81 unit townhouse complex was built in Kitchener, Ontario on an old municipal garbage dump and adjacent to a major landfill site. The combination of odours and dangerous levels of methane soon caused the householders to leave. The complex has been largely vacant for ten years. CMHC and CH2M Hill Engineering explored ways to reduce the levels of methane concentration in the houses. A radon remedial measure, subslab ventilation, proved very effective in keeping indoor methane concentrations below 100 ppm, even in the townhouses with the previously recorded levels up to 30,000 ppm. Researchers are now investigating the ambient air impact of the subslab venting, the soil pressures required for effective venting, and the regulatory maze that needs to be traversed before the units can be reoccupied"--Introduction.
