Murray River 
 The longest river in Australia is Murray river covering 2508 kilometres  in length, 
source of water are freshly renewed by mountain Alps. The stretch of river is bend south 
towards sea at Morgan for 315 kilometres meeting ocean at Lake Alexandrina. It is one of the 
main river for the fresh water supply to the Australian community. For centuries it was not 
polluted but at the end of 20th century industrial revolution starts polluting the mainstream of 
river by draining industrial wastes directly into the river once PCB commissioned the strict 
law helped in reduction of pollution with stringent practise. However the mass polluted 
components in the river still exists hence the analysis are performed for finding the vital 
cause for the Murray river degradation. The data from the spreadsheet are used for analysis 
with the hypothetical reasoning of major pollutants with BOD, COD and associated 
parameters. 
Section 1- Data Quality Evaluation 
 The procedure framed by Klimisch Evaluation System (KES)  is used as it's the best 
reliable methodology for the analysis of pollution data. It is comprised of Reliability, 
Relevance and Adequacy  principles. The data given in spreadsheet aligns with all these three 
terms as the main parameters of hard water constituents like Ca, Mg .., are given in depth 
detail since early 1990's.
