A joint inspection of the Withyhedge landfill site will be carried out this week, after local residents claimed that foul smells had returned since the site near Haverfordwest reopened this month.

The inspection by Natural Resources Wales and Pembrokeshire County Council officers is due to be carried out on Wednesday, January 29.

Campaigners from the ‘Stop the Stink’ group have stated that people in the Crundale, Haverfordwest and Spittal areas continued to be subjected to "horrendous smells again".

One campaigner told BBC Wales: “The public inquiry is the only way to get to the bottom of what's happened, because we've been flanneled by NRW, by public health, Pembrokeshire council.

“All of these leaders need to take a back step and look at what they have not achieved. It's disgraceful.

“It's our only route now, because we've waited for 14 months for this problem to go away.”

NRW said that it had received 34 odour complaints since January 6, and the complaints had increased since January 16, but inspections had not identified any cause of offsite odours.

A spokesperson said: “In response to a rise in complaints in recent days, officers from NRW and Pembrokeshire County Council have been in the locality responding to odour incidents as reported. No odours attributable to the landfill have been detected.”

RML who own the site said that it had reopened following comprehensive engineering works; the installation of improved gas management equipment to help avoid the release of odour from cells in the future; extensive air quality checks; and stringent waste sampling and analysis in collaboration with Natural Resources Wales.

A spokesperson said: “RML and our partners are satisfied that historical issues at the site are fully resolved, whilst both Natural Resources Wales and Pembrokeshire County Council have confirmed any odours detected in the area are no attributable to the Withyhedge landfill site.”
