(b) what percentage, and how many Gigalitres, of Perth’s potable (domestic) water supply comes from groundwater abstracted from the Jandakot Mound; (c) how many Gigalitres of water were abstracted from the Gnangara Mound in each of the last 5 years and to date in 1995 for the following - (i) horticulture; (ii) other agricultural industries; and (iii) other commercial and industrial uses; (d) what was the total non-domestic water (in GL) abstracted from the Gnangara Mound in each of the last 5 years and to date in 1995 for the following - (i) horticulture; (ii) other agricultural industries; and (iii) other commercial and industrial uses; (e) is the Minister aware that the Department of the Environment (DoE) estimates that there has been a decline of more than 500GL in the aquifers of the Gnangara and Jandakot Mounds since 1979, equivalent to four times the storage capacity of the Serpentine Dam; and - (i) if so, why has the public not been informed about what is happening to the largest source of water supply to the metropolitan area; (f) are the groundwater licences still being issued by the Water and Rivers Commission (now Department of the Environment) for private abstraction from the Gnangara Mound; (g) how many private groundwater licences are there on the Gnangara Mound; (h) how many of these private groundwater licences from the Gnangara Mound are for more than 5000 KL; and (i) how many of these private groundwater licences from the Gnangara Mound were checked for compliance annually in the last 5 years?

It is also important to note that declining surface water levels over the Mounds is substantially due to the drying climate, and the ongoing significant decrease in rainfall experienced since the mid 1970's, and not abstraction levels. (a) 58.1%. 132.9 GL in 2004/2005. (b) 2.5%. 5.8 GL in 2004/2005. (c) Water allocation licences are issued for horticulture on the Gnangara Mound based on advice from the Department of Agriculture on the amount of water required for various crops. The licensing data base does not make provision for historical data to be provided. To date, the amount that has been allocated is as follows :- (i) horticulture - 42.6 gigalitres per year (ii) other agricultural industries - 14.9 gigalitres per year (iii) other commercial and industrial uses - 1.2 gigalitres per year (d) Same as for (c). (e) Yes (i) The total amount of water stored in the superficial water table aquifer on the Gnangara Mound is estimated to be about 25,800 gigalitres. Hence only about 2% of the aquifer storage has been used over a period of 25 years. This information is publicly available in the Department of Environment's (DoE) State of the Gnangara Mound report (July 2005). This will also be discussed with the public during the consultation process associated with the preparation of a management plan due for completion by mid 2006. (f) Yes, but only in areas where the DoE considers they will not exacerbate water level declines. (g) 8,544. (h) 2,617. (i) 2001 14 2002 3 2003 132 2004 512 2005 160 In the past three years the Government has taken significant steps to improve the delivery of core water resource management functions, culminating with the decision to establish a focussed Department of Water. Funding for core functions has increased by almost 50 per cent, from $50.6 million in 2003/04 to $74.4 million this financial year. This includes a three year $6m program to meter private groundwater abstraction on the Gnangara Mound. The additional funding will ensure that core water resource activities such as metering, monitoring and compliance will be enhanced in the future.

Although the total amount of water licensed for abstraction from the Gnangara and Jandakot Mounds has increased since 2000/01, over that time public water supply abstraction from the superficial aquifer has decreased in environmentally sensitive areas and additional water has been abstracted from the deeper confined aquifers, which has a greatly reduced impact on surface water levels.
It is also important to note that declining surface water levels over the Mounds is substantially due to the drying climate, and the ongoing significant decrease in rainfall experienced since the mid 1970's, and not abstraction levels.
(a) 58.1%. 132.9 GL in 2004/2005.
(b) 2.5%. 5.8 GL in 2004/2005.
(c) Water allocation licences are issued for horticulture on the Gnangara Mound based on advice from the Department of Agriculture on the amount of water required for various crops. The licensing data base does not make provision for historical data to be provided. To date, the amount that has been allocated is as follows :-
(i) horticulture - 42.6 gigalitres per year
(ii) other agricultural industries - 14.9 gigalitres per year
(iii) other commercial and industrial uses - 1.2 gigalitres per year
(d) Same as for (c).
(e) Yes
(i) The total amount of water stored in the superficial water table aquifer on the Gnangara Mound is estimated to be about 25,800 gigalitres. Hence only about 2% of the aquifer storage has been used over a period of 25 years.

This will also be discussed with the public during the consultation process associated with the preparation of a management plan due for completion by mid 2006.
