A New Water Quality Index for Environmental Contamination Contributed by Mineral Processing: A Case Study of Amang (Tin Tailing) Processing Activity

Mohsen Nasirian

Abstract:
A Water Quality Index (WQI) is a mean to summarize large amount of water quality data into simple terms (e.g., good or bad, clean or contaminated) for reporting to authorities management and the public in a consistent manner. Few water quality index systems have been developed and none are widespread use. Available indices are either highly specialized (e.g., those applicable only to lakes) or very simple in terms of the numbers of variables considered. None seem to be geared to the protection of multiple water uses or to encompass the variety of measurements of water quality. Current WQIs provide indications of the quality of water influenced by domestic and some general industrial effluents. Unfortunately they were not formulated to quantify the quality of water impacted by mining. This study looked at the suitability of using current WQIs to describe water quality contributed by mining activities and in specific tin mining and amang (tin tailing) processing. An amended and new WQI was introduced integrating parameters relevant to such activities. A vast field measurements including physical, chemical and radionuclides analysis were carried out. A questionnaire survey was also carried out to facilitate the selection and integration of the best and appropriate water quality parameters. In this particular study, Water Quality Index (WQI) was calculated by summing up of nine individual quality parameters i.e., pH, NO3-, radionuclides, dissolved oxygen, PO43-, heavy metals, electrical conductivity, SO42- and suspended solid.
