Abstract

Water Quality Index (WQI) is one of the most powerful and effective tools for analyzing overall characteristics of water quality any reservoirs, its way to transfer information on water quality trends to policy makers and the general public is with Indices. Our objective was to evaluate ground water quality in the Rooppur Nuclear Power Plant (RNPP) area, Pabna, Bangladesh using a Canadian Council of Ministers of the Environment (CCME) WQI. WQI represent a clear scenario about the usability of the water for different purposes. Water quality indices are useful for concise information in order to achieve a national perspective. Attempts have been made to review the WQI criteria for the appropriateness of drinking water sources. Till now any methodology is not developed for evaluation of water quality index purposes in Bangladesh. At the very recent a few researcher try to use WQI method for giving WQ rating in Bangladesh. But, has no specific guideline for indexing water resources. This study to explore a potential WQ indexing method which applies easily and measure overall WQ for managing purposes. Besides, the present article also highlights and draws attention towards the development of a new and globally accepted “Water Quality Index” in a simplified format, which may be used at large and could represent the reliable picture of water quality. In the present paper, water quality index (WQI) was estimated for the groundwater of Rooppur Nuclear Power Plant area within the study period. The study also identifies the critical pollutants affecting the groundwater quality during the study period. The indices have been computed for the winter season at 17 locations, namely GW1, GW2, GW3 etc. It was found that the water quality ranged from poor to marginal category at all locations. Alkalinity, Conductivity, BOD, DO, Iron, Arsenic, Lead, Nitrite and fecal coliforms were found to be critical parameters.

Highlights

  • A water quality index (WQI) is a tool to assess the status of water quality at convinced times and locations

  • This study focus to evaluate the WQI in ground water of Rooppur Nuclear Power Plant (RNPP) areas

  • The frequency with which the objectives are not met is highest between the ranges 65 and 70 and the amount by which the objectives are not met is highest between 95 and 100. It was observed (Table 6) that the range of Council of Ministers of the Environment (CCME) WQI for ground water at RNPP area at GW1, GW7, GW9, GW10, GW14, GW15 and GW16 sampling site falls under poor category and other sampling sites falls under marginal category during study period in January 2017

Summary

Introduction

A water quality index (WQI) is a tool to assess the status of water quality at convinced times and locations. It helps to gather whole scenarios of water quality parameters into useful information that is modest and comprehensible and can be used by the state agencies as well as the general public. Groundwater reservoirs one of them and more reliable sources of fresh water These sources polluted by the various natural and human activities. Human activities are more significant factors whose are influence Physico-chemical characteristics of water quality; gradually this trends increasing very rapidly in developing countries in the world. In wide-ranging terms, water quality can be classified into three broad categories, namely physical, chemical and biological and each category has a number of parameters [18]
