PERTH
MAJOR SPORTS STADIUM — BOREHOLE DRILLING
265. Hon KEN TRAVERS to the Leader of the House representing
the Minister for Sport and Recreation:
I refer to the
drilling of boreholes over the proposed Burswood stadium site and surrounding
areas.
(1) Do any of
these boreholes within the contaminated sites contain possible asbestos?
(2) If yes to

fibres as a result of this drilling?

I thank the
member for some notice of the question.
(1) On the
basis of previous investigation and historical records, the possibility of
drilling encountering contaminants including asbestos was highlighted in the
tender documentation for the work in question. Tenderers were required to
address this risk in their proposed methodology.
(2) The
drilling contractor has adopted a wet drilling method, with all spoil recovered
from boreholes in wet slurry form stored in containers onsite and trucked
offsite to an authorised landfill site for disposal. This methodology ensures
that any asbestos fibres that might be encountered cannot become airborne,
thereby eliminating the risk to human health.
