STOMPer G sent in these pictures of copper slag being offloaded at Mandai Road and wondered if it was illegal to do so, as it is a water catchment area.
In an email to STOMP, the STOMPer sent in these pictures which he snapped on Jan 12 and wrote:
"Why is copper slag being offloaded at Mandai Road?
"Isn't Mandai a water catchment area - will there be a danger of slag seeping into water supply?
"Perhaps the authorities should comment on this."
Wait a minute... this looks a little familiar.
