Title: Pumping Bores in the Northern Territory

Citation Date:2014-01-01

Date Type:creation

Custodian:Department of Environment, Parks and Water Security



The Water Resources Division of Department of Land Resource Management (DLRM) carries out pumping tests on boreholes in order to determine optimum pumping rates and pump depths. They are also used to determine aquifer hydraulic parameters. This dataset lists all boreholes that have been pump tested or that have been used as observation bores in pump tests

Data Quality

Lineage:Basic pump test data has been recorded in a register since the 1950's. Separate pump test books were kept at the Water Resources offices in Alice Springs and Darwin. Parts of that data were entered onto a spreadsheet in January 2014. Bore locations were obtained from the HYDSTRA database and the dataset was turned into a Shapefile. Information such as water quality and recommended pump rate were extracted manually from bore files using NRMaps.

Positional Accuracy:Before 1995 - the positional accuracy of sites is deemed low with a standard deviation of +/- 300 - 10 000 metres. A poor positional accuracy resulted from inconsistencies with the collection/storage of positional data and original mapping formats. Some of locational accuracy of these sites is being upgraded from poor to high with the use of GPS. From 1995 - the positional accuracy of sites is deemed high with a standard deviation of +/-3 - 10 metres with the use of GPS.

Attribute Accuracy:The accuracy of the sites attribute information is considered high and conforms to the Department Standards at time of capture.

Logical Consistency:Not Applicable.

Completeness:Continually updated and maintained.
