Introducing the modification of Canadian water quality index

Abstract There exists currently in water resources management a significant disconnect between stakeholders, policymakers, and decision-makers. Research has demonstrated the usefulness of water quality indices for water quality assessment and management. Built on existing works, the modified Water Quality Index must possess the following fundamental properties: independence from a particular set of quality parameters and sensitivity to individual bad parameters. Based on a literature review of relevant works on water management and theories on water quality indices, the Canadian Water Quality Index (CCME WQI) has been selected as the basis because it has the first of the properties mentioned above. Analysis of the implicit statistical exploration demonstrated that CCME WQI is also a quality index for the quality of water control. Nevertheless, there are situations where CCME WQI classifies the water as bad, but more detailed analysis shows that the water is good. This research presents a modification of CCME WQI, called the Modified Water Quality Index (MWQI). MWQI behaves largely similarly to CCME WQI but provides fairer judgment in cases where the statistical factors of CCME WQI paint a skewed picture.
