Abstract

Water Quality Assessment of Ahoada River and its Suitability for Use

Highlights

  • Freshwater ecosystems exhibit high natural variability in their physical and chemical properties due to differences in geology and climate

  • The present study aims at examining some of the physical, chemical and biological characteristics of this river and the heavy metal content to determine its water quality and its suitability for both domestic and industrial use using the Weighted Arithmetic Water Quality Index method (WAWQI)

  • Water quality index of Ahoada River was based on the analysis of various important parameters

Summary

Introduction

Freshwater ecosystems exhibit high natural variability in their physical and chemical properties due to differences in geology and climate. All human usage of water either for drinking, irrigation, recreation and industrial processes has some quality criteria requirements to make it acceptable. This quality requirement can be addressed in terms of physicochemical properties of such water (Maitera et al, 2010). Stormwater runoff carries pollutants such as dirt, chemicals and fertilizers directly into streams and rivers where they seriously harm water quality (Wood and Bernknopf, 2003). These activities affect the physical process of river growth, modify streams structure and further influence the functions of the river system. The river is getting deeper due to dredging; it is no longer used for drinking and fishing activities, it is polluted with a lot of organic matters and other pollutants
