CETEC conducted air quality testing in the M5 east tunnel in August and this was reported on 27th August on Seven news in Sydney.
CETEC has a continuing interest in improving air quality in our environment. Poor air quality can have a negative impact on community health and in particular for those who are sensitised to pollution including the young, the elderly, asthmatics and those with poor lung function.
Since the air quality test results were reported on 27th August and resulting from the public pressure, the NSW Roads Minister Duncan Gay has been reported as saying in regards to the air quality in the tunnels that "This tunnel is pretty ordinary in many respects". He has since committed to publishing the monthly air test results from inside the tunnel and displaying a warning sign at the tunnel entrance.
