Residents of a housing estate in Longford are meeting with the Health Service Executive today to determine whether they need to be evacuated from their homes.
Longford County Council and the HSE have been monitoring gas levels at the Gleann Riada estate on the Strokestown Road in Longford since a suspected gas explosion occurred at one of the houses in March.
Gleann Riada is a private estate partly controlled by the National Asset Management Agency (Nama), which demolished a vacant apartment there in July.
The council has contracted specialists to investigate the estate's sewerage system in an effort to ascertain the source of dangerous gases detected in some houses.
A number of residents have been advised not to light fires in their homes. They were also asked to open doors and windows and leave their homes if strong odours were detected.
