Technical Report WRD94031 Viewed at 15:07:29 on 29/07/2010 Page 7 of 34. 3. RESULTS STUART HIGlf"wAY Bore &'\1 29012 (grid ref 987-108, 1 :100 000 map Gorrie) penetrated approximately 40m of clays and fine sands overlying limestone and siltstone of the Tindal Limestcne to a total depth of l21.8m. Composite logs of the holes are included in the attachments. Pump testing subsequently determined a high yield for the bore and an extraction rate of lOLls has been recommended. If higher extraction rates are required, Water Resources Division should be consulted. Bore RN 29013 (grid ref 292-450, 1:100 000 map Larrimah) was drilled through 32.5m of clays and fine sands overlying limestone to 95.7m. Basalt of the Antrim Plateau Volcanics was encountered to the total depth of 103. 3m. Pump testing again determined a high yield for the bore and an extraction rate of lOLls has been recommended. If higher extraction rates are required, Water Resources Division should be consulted. Til/ater quality results from samples taken during pump testing are included in Table 1. The bores yielded water of potable quali ty (A~IRC/NHr-L'l.C, 1987) except for high total dissolved solids caused by excess hardness. These parameters are not directly health related and reflect the carbonate source rocks in the area. Regular inspection of pumps and fittings is recommended to ensure that scale buildup does not affect the operation of the bores. DELAMERE ROAD Bore RN 29090 (grid ref 191-009, 1:100 000 map Killarney) was drilled through siltstones, limestones and mudstones of the Montejinni Limestone to a depth of approximately 60m overlying basalt to a total depth of 70. 7m. A small seepage of vlater was encountered at the limestone/basalt interface, however not enough to provide a water supply. The hole was sealed at the surface and left open to depth for further monitoring.
