Groundwater levels in the bores were recorded at depths of 2.48m, 2.42m and 1.15m below
ground surface. Test sites have not been surveyed for location or level: however, they were
targeted approximately on the 10m AHD contour. Consequently, standing (at rest) groundwater
levels would be at an elevation of approximately 7.5m to 9.0m. This would indicate a
reasonable amount of available drawdown (above sea level) for water bores constructed at
these locations.

During purging of the bores for groundwater sampling, the Grundfos MP-1 pump intermittently .
ran dry in bore GW, i.e. the bore yield could not maintain the pump demand. No such

problems were encountered in the sampling of bores GW2 and GW, indicating better supply

potential at these locations. Though the drilling program and yield testing has been limited, it is

considered that appropriately constructed water supply bores in the Landsborough Sandstone in

close proximity to test locations GW2 and GW3 wiil provide reasonable water supplies of the

order of 1L/s to 2L/s.

Water quality for each of the test locations based on the laboratory analysis of groundwater

samples is summarised in Table 6.2.1. The laboratory results are assessed in comparison with
guidelines for potable waiter quality as outlined in NHMRC (1996, updated September 2007).
