Ngarradj (Swift Creek) monitoring data 2011-2012

The graphs on this web page show the following key chemical indicators for the 2011-2012 wet season plus water level and flow rate of the creek at the compliance point gauging station (JSC). Data for physico-chemical parameters and filterable analyte concentrations from previous wet seasons can be found at Ngarradj grab sample monitoring data 2001 - 2009 and Ngarradj monitoring data 2010-2011.

The Supervising Scientist's interpretation of the data in these charts is available at:

Conductivity and Water Level in Ngarradj

The conductivity guideline of 21 μS/cm was determined statistically from historical weekly grab sampling data, and applies to water quality measured in grab samples. This guideline may be exceeded occasionally due to natural events but should not be exceeded due to mining activities. The Supervising Scientist has a current research project to develop an appropriate interpretive framework for the EC  data produced by  the continuous monitoring program.
