More drilling on northern Gnangara Mound
Released 16 May 2008
Further efforts have begun on a groundwater monitoring program about 20 kilometres west of Gingin as part of the State and Federal Government's commitment to ensure the sustainability of Gnangara groundwater for drinking and commercial purposes and to protect the environment.
The Department of Water will install nearly 48 new groundwater monitoring bores in the northern portion of the Gnangara Mound at 12 sites between Military Road in the west and Coonabidgee Road in the east.
The department's groundwater investigation section manager, Seth Johnson, said the drilling program was part funded by the Australian Government Water Fund - Water Smart Australia program.
Mr Johnson said the drilling project into the Superficial, Leederville and Yarragadee Aquifers followed work postponed in July 2007 due to drilling difficulties. The monitoring bore installation was now expected to be completed by September.
"There will be four monitoring bores at each site - the shallowest about ten metres deep, and the deepest up to 320 metres in depth," Mr Johnson said.
"The new bores are an additional part of the department's State Groundwater Investigation Program to develop a better understanding of the groundwater systems and improve the existing groundwater monitoring network.
"The data we collect from this drilling will be used to bolster our knowledge of the groundwater resources and the connection between aquifers in the northern Gnangara Mound.
"The new information will also contribute to more accuracy in the department's Perth Regional Aquifer Modelling System, as well as assisting with ongoing management of this important water resource.
"With the increasing demand on local water resources made by farmers, horticulture, industry and the community, and the need to maintain Perth's unique wetlands and native vegetation, this project will help with monitoring and assessing impacts related to climate change and the continued expansion of the metropolitan area."
