I refer to the Water Authority monitoring of aquifers in the Three Springs Shire and Mingenew Shire area, and ask -
(1) What are the aquifers and relevant data, below the following coordinates -
(a) Latitude 29 22’ 37.3582” and Longitude 115 31’ 34.2988”;
(b) Latitude 29 19’ 02.3213” and Longitude 115 33’ 45.2108”;
(c) Latitude 29 10’ 28.9491” and Longitude 115 24’ 07.2406”;
(d) Latitude 29 09’ 35.6925” and Longitude 115 23’ 04.2286”; and
(e) Latitude 29 06’ 35.4831” and Longitude 115 22’ 46.7485”?
(2) Does the department have any bores, logs or records of the drawdown of aquifers at these locations?
(3) In relation to (1)(a)-(e), will the Minister table this data?

(a) The main aquifer is the Yarragadee aquifer.
The watertable is likely to be approximately 40 metres below ground level.
Groundwater is likely to be fresh to brackish near the watertable and brackish to saline at depth.
(b) The main aquifer is the Yarragadee aquifer.
The watertable is likely to be approximately 40 metres below ground level.
Groundwater is likely to be fresh to brackish near the watertable and brackish to saline at depth.
(c) The main aquifer is the Yarragadee aquifer.
There is a geophysical log available for Irwin View OB1-76.
The watertable is currently 62 metres below ground level in Irwin View OB1-76. A hydrograph is available and it shows an increase in water level from 112 m AHD in 1978 to 119.5 m AHD in 2010. This is an increase of 0.23 metre/year.
Groundwater in the Yarragadee aquifer is fresh near the watertable and brackish to saline at depth.
