Water well monitoring data from wells on Aboriginal lands (Pitjantjatjara, Yalata and Nepabunna) are summarised for the period April to October 2000. Equipment failure was high, with faults recorded at 17 wells, particularly of the 2100P standing water level measurement units. These units are progressively being replaced with a modified design that should reduce failure frequency. The rainfall events that occurred in the central and eastern parts of the Pitjantjatjara Lands in February 2000 continue to recharge aquifer(s) at Amata, Pukatja and Indulkana, with the groundwater levels at Amata rising by 3-4 m, and possibly still continuing to rise.
