A reader, who claims to be a chemical engineer, has written to tell us of a danger of a sewer gas explosion in Neath's Old Market Street.   He urges to the council to find out where the smells are coming from in order to trace the source of the leak(s).   Several readers have now written in to tell us of their concern.
