GNANGARA GROUNDWATER AREAS
ALLOCATION PLAN
504. Hon ALISON XAMON to the minister representing the
Minister for Water:
I refer to the Gnangara sustainability plan, which states at
page 61 that the Department of Water will work over the 2010–11 period
with the Department of Environment and Conservation to update the current acid
sulfate soils risk map and review procedures for addressing identified acid
sulfate soil risks when licensing.
(1) Has the acid sulfate soils map been updated?
(2) Have the procedures for addressing identified acid
sulfate soil risks when licensing been reviewed?

AnswerView source ↗

I thank the member for some notice of the question.
(1) I believe
that the honourable member is referring to the ''Gnangara groundwater
areas allocation plan''. Consistent with environmental management action
3 on page 61 of this plan, acid sulfate soil sampling has been undertaken by
the Department of Water and the Department of Environment and Conservation.
After considering the additional soil sampling data, DEC concluded that the
acid sulfate soils risk map boundaries remained appropriate. The current risk
maps and underlying soil sampling data are publicly available through Landgate's
Shared Land Information Platform website.
(2) Yes.
