Residents in west Belfast say they've had enough of a foul smell which has been plaguing them for months.
he smell was traced to the Mullaghglass landfill site, which is operated by Alpha Resource Management, and residents in the Colin, Hannahstown and Glen Road areas were told last October that the problem would be sorted.
But those living near the site are still suffering the ill-effects and according to mum-of-three Mairead Connolly, who lives in Mount Eagles, the stench is now worse than ever.
"We've gone past frustration now," she said.
"It's just unacceptable that we have to put up with this. We're angry. We've put up with it for so long and it's getting worse.
"Complaints from residents are mounting. We have people complaining of nosebleeds, headaches, breathing difficulties. We need something done urgently."
Mairead said the smell reached new heights as her family tried to celebrate Christmas.
"The kids didn't mention it, they expect it now. But on Christmas Eve we could notice the smell getting stronger and on Christmas morning it was vile, coming up through toilets, sinks and through windows even though they were closed."
The Northern Ireland Environment Agency said it remains aware of the ongoing issue and is continuing to work to end the distress being experienced.
"NIEA is aware of the foul odour issue which local residents have been experiencing and have been undertaking regular odour monitoring at the site and in the surrounding area to try to pinpoint the exact source of the problem," a spokesperson confirmed.
"NIEA has also been engaging with the operator of the Mullaghglass landfill who has been instructed to conduct detailed methane surveys to try to detect any point sources of fugitive emissions around the landfill.
"In addition the site operator has been asked to prepare an odour management plan to ensure that measures are in place to effectively deal with the more recent waste deposits which seem to be generating landfill gas earlier than expected.
"Monitoring and site visits to Mullaghglass and the surrounding area by NIEA will continue, and will include joint visits with council environmental health officers. NIEA will continue to update local elected representatives on progress."
The source of the smell had been traced to the landfill site last October, giving residents hope that the issue would finally be dealt with.
The NIEA had said that inspections "have substantiated complaints from residents in Mount Eagles that there is an odour nuisance in the area which has been traced to the Mullaghglass landfill".
The agency said it had been in discussions with the operator to address the issue and that the smell was caused by "seepage of landfill gas".
It added that the operator had brought forward plans to install gas extraction wells, with work to begin that month.
It's understood the landfill site is nearing capacity and is due to close in December this year.
