EasyChair Preprint no. 3093

Abstract

Groundwater is one of our most important natural resources. To establish a sustainable and optimal use of this natural resource its quality has to be assessed. The present study consists of an analysis of groundwater quality within the vicinities of Amayizhanjan thodu, one of the most polluted rivers in the Trivandrum city. The samples collected from the wells located along the banks of the river were tested for various physio-chemical and biological pa-rameters. Water quality index for parameters such as pH, total dissolved sol-ids, hardness, dissolved oxygen, biochemical oxygen demand, chlorides and to-tal coliform has been determined. Spatial distribution maps of all water quality parameters including Water Quality Index map have been developed using Geographical Information System (GIS). Analysis reveals the present status of groundwater quality of study area and recommends that the groundwater of the region needs field-specific treatment before putting it to use. Additionally, the authorities need to put a strict regulation of waste disposal along Ama-yizhanjan thodu.

Keyphrases: GIS, Ground water quality, Spatial distribution maps, Water Quality Index
