FORRESTFIELD–AIRPORT
LINK — DEWATERING
1157. Hon Dr STEVE THOMAS to the minister representing the
Minister for Transport:
I refer the Forrestfield–Airport
Link project, and the report in this week's The Sunday Times
telling us that tunnel boring is now occurring under the Swan River.
(1) Does the
project include dewatering?
(2) What amount of water has been
produced in dewatering?
(3) Where has
that water been disposed of?
(4) Has any of the water been
disposed of into the Swan River system?
(5) If yes to
(4), did any of that water entering the Swan River system contain PFAS; and, if
so, at what concentrations?
Hon
STEPHEN DAWSON replied:

656 000 kilolitres has been produced.
(3) The majority
of water has been disposed of via onsite reinjection, with a smaller amount to
the sewer.
