Resource management technical reports

‘Cockatoo Sands’ is a common name for the Cockatoo Sands family of soils (comprising red to yellowish-red sands, sandy earths, and loamy earths) that have formed from quartz sandstone colluviums in relatively isolated patches throughout the East Kimberley region of Western Australia and the Northern Territory. Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging or inundation. These characteristics allow them to be cultivated and prepared for planting various crops during the wet and dry seasons of northern Australia.

Expanding agricultural production onto the Cockatoo Sands around Kununurra …

Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, Ivan Marin, Ilya Turbanov

International Journal of Speleology

Based on the morpho-genetic study of stygobiotic shrimps from the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae), a hydrogeological connection of a number of distant caves in Central Abkhazia of the southwestern Caucasus is satisfied, which indicates the possibility of using biospeleological studies in some cases to identify karst hydrosystems together with traditional hydrogeological methods. Moreover, a new stygobiotic atyid shrimp from the genus Xiphocaridinella, X. kelasuri sp. n., is described based on morphology and analysis of mitochondrial cytochrome oxidase I DNA sequences from three distant caves. The new species is genetically divergent from relatives and phylogenetically related to …


Hydrogeology Of The Gillingarra Palaeochannel, Russell Speed, Adele Killen Feb 2020

Hydrogeology Of The Gillingarra Palaeochannel, Russell Speed, Adele Killen

Resource management technical reports

Previous groundwater investigations had identified the presence of palaeochannel sediments under the Capitela Valley in the Perth Basin, about 25 kilometres south-west of Moora. The sediments of this Capitela Palaeochannel were thought to form a discrete aquifer of good quality groundwater suitable for agriculture.

To improve our understanding of the Capitela Palaeochannel, its distribution, water quality and potential as a groundwater resource, we undertook an airborne electromagnetic (AEM) geophysical survey of the area in December 2012. This led to the discovery of a palaeochannel located in the Darling Range between Gillingarra and New Norcia, and we named this the Gillingarra …

Biogeochemical Behavior Of Dissolved Arsenic And Uranium Concentrations In Public Water Supply Wells, Kevin J. Mcvey May 2009

Biogeochemical Behavior Of Dissolved Arsenic And Uranium Concentrations In Public Water Supply Wells, Kevin J. Mcvey

School of Natural Resources: Dissertations, Theses, and Student Research

Public water supply (PWS) wells currently contain dissolved uranium concentrations above the federally mandated maximum contaminant level (MCL) of 30 ppb (parts per billion) and dissolved arsenic concentrations above the 10 ppb MCL. Both uranium and arsenic are known to cause various forms of cancer in humans. Variations in total uranium concentrations in PWS wells in Nebraska indicate a relationship to the duration and rate of pumping in specific wells. Although total arsenic concentrations show some variability over time in specific wells, the relationship to pumping is not as clear. Previous studies show that iron and sulfur bacteria present in …
