Araluen Water Quality Sampling Report -2000

The rural community of Araluen, located 56 km northwest of Moruya, is almost totally
dependent on groundwater for their domestic, stock and agricultural needs. The Araluen
Valley groundwater resource, is deemed of highest beneficial use, as it provides drinking
water, water for large scale crop irrigation, plus stock and domestic supplies.

This aquifer system is also ranked as the third most ÔÇ£at riskÔÇØ aquifer in the Sydney South Coast Region, based on both the quantity and quality pressures on the groundwater resource.

In response to concern over declining water levels in local wells and bores, the Department of Land and Water Conservation (DLWC), undertook a preliminary groundwater study in the
Araluen valley in September 1997. The study aimed at gaining an insight into the groundwater resource and addressing issues raised by local groundwater stakeholders.

The groundwater sampling component of the 1997 study (Sanders, 1997), discovered water
quality issues within the Araluen valley. The results indicated that 14 of the 15 bores/wells sampled showed signs of faecal pollution. The Health Department was subsequently alerted to the study findings, and Araluen residents were advised to boil their drinking water. In response to the 1997 study further work was undertaken by DLWC. A DLWC drilling program was undertaken in 1998 to install nine monitoring bores throughout the valley.

Subesquently, all of the nine DLWC monitoring bores have had automatic groundwater level
recording devices installed, with ongoing maintenance and data retrieval.
