They have dug the same bit of pavement up repeatedly over the last 12

have had the smell analysed and its not their gas....

So what could it be?

Its an 18th and 19th C mining area, might it be gas rising from the old
mines? They say mines would be too deep...

it is probably coming out of the old pipes. We had a smell for over year
when they replaced our mains.
