Drilling for answers in Perth's Wetlands
Released 23 Apr 2007
The first stage of an extensive four year study conducted by the Department of Water into better managing groundwater and protecting wetlands on the Gnangara and Jandakot mounds has started.
Until late May 2007, staff from the Department of Water will be installing groundwater monitoring bores at six key ecologically significant wetlands.
The six sites include North Lake, Lake Forrestdale, Egerton Seepage, Lake Joondalup, Lake Nowergup and Lake Mariginiup.
Sandie McHugh, Hydrogeoloist and Project Manager with the Department of Water said the new monitoring network would examine surface-water-groundwater interactions and assess the impact of declining water levels.
"It will help us reconstruct past water levels and tell us how the wetlands have evolved over time," Dr McHugh said.
Several drill rigs will be used to complete the work, but with minimal disruption to local communities and the environment.
"The environmentally sensitive machinery will minimise the impact on vegetation and soil at all times."
"We have consulted extensively with community and Indigenous groups to ensure cultural and environmental values intrinsic to the wetlands are protected and enhanced." Dr McHugh said.
Once the work is completed the Department will monitor the bores each month.
