Air Quality Monitoring

Apr 2, 2020

We have had to postpone  the monthly visits to gather data on the air quality in the tunnel. We have completed three so far and plan to do this for a whole year, but that programme may need to be extended. The visit for May was planned to be one in which we would be entering via the Blaengwynfi air shaft managed as ever by the highly skilled and professional team from MRS (Mines Rescue). At that visit, we were expecting to be able to take a number of visitors into the tunnel to show them its remarkable state. We shall have had to postpone that visit as well.
