Bores with Hydrochemistry
Hydrogeochemistry data provides useful information about the quality of groundwater and the processes affecting it. The Hydrogeochemistry layer depicts bores with hydrogeochemistry data available through the Australian Groundwater Explorer. The colour of the layer represents the number of hydrogeochemistry measurements on record, from dark green (>40) to light green (<20).
<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>The hydrochemistry data in the Explorer has been sourced from Geoscience Australia (GA) web services and the CSIRO Data Access Portal.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>GA collects hydrochemistry data on a project basis. CSIRO has curated a groundwater hydrochemistry dataset by collating and standardising data from most State and Territory lead water agencies. At this stage the Explorer only contains a pilot of the CSIRO hydrochemistry data for the Northern Territory. Data for remaining States will be added in the near future.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>GA and CSIRO datasets include a range of hydrochemistry data including:</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Field measurements and laboratory analyses, such as pH and electrical conductivity</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Major and minor ions, such as sodium and calcium</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Environmental tracers, such as oxygen-18, carbon-13</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Radioactive isotopes, such as chloride-36 and carbon-14</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Nutrients, such as nitrate as N</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Gases, such as nitrogen gas</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>In addition to this CSIRO has calculated variables such as saturation indices, which are derived from the hydrochemistry measurements. Information for methodologies used by CSIRO, including the saturation indices, is available from the CSIRO Research Publications Repository.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>GA uses project-based bore IDs, which may be different to the bore IDs used by State/Territory agencies and the National Groundwater Information System (NGIS). While CSIRO has collated State datasets and bore IDs should match NGIS, some bore IDs may not due to missing hole and pipe numbers.</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>Information about groundwater hydrochemistry fields:</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>BoreholeIdentifier—State and borehole number e.g. WA/1027477</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>SamplesCount—Number of samples taken at a particular bore (water sample taken from a particular bore at a particular day and time)</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>AnalysesCount—Number of analyses taken at a particular bore (test for particular physical or chemical property e.g. Electrical Conductivity (uS/cm), Magnesium (mg/L))</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>SamplesMaxDate—Most recent date when sample was taken</SPAN></SPAN></P><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>SamplesMinDate—Earliest date when sample was taken</SPAN></SPAN></P><DIV><DIV><P><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV>
