Abstract

Industrial activity is one of the major reason of groundwater contamination. Arsenic is one, which is responsible for the contamination of the groundwater. Its testing in groundwater is considered as an important activity due to its serious effects on human health. Arsenic problem in Pakistan has been identified recently as a result of field testing. In Faisalabad, arsenic has been found in groundwater within permissible limit. But due to increasing industrial activities the concentration of arsenic is increasing day by day. Drain passing through the city is one of the sources of arsenic in groundwater. The research work was conducted at Syedabbad, Faisalabad. Samples were taken from the selected drain portion and from the groundwater by the help of water pumps. The sampling points were drawn on GIS map by the help of GPS receiver to study the spatial variability of arsenic contamination The results shows that there 10109.9 mg per second intake of arsenic due to drain. Results show that there is no temporal variability of arsenic within the research period but they have spatial variability.

Highlights

INTRODUCTIONGroundwater is an important source of drinking water and its quality is subjected to threat due to manmade activities like industrial development as mandatory to cop the demands of growing population which is one of the major the focal reason for groundwater contamination especially in industrial cities like Faisalabad

Some area of Syedabbad located near the University of Agriculture Faisalabad was selected where many cases of skin diseases were observed in pre-research survey representing the possible arsenic contamination and unlined portion of drain was passing through the area

Summary

INTRODUCTION

Groundwater is an important source of drinking water and its quality is subjected to threat due to manmade activities like industrial development as mandatory to cop the demands of growing population which is one of the major the focal reason for groundwater contamination especially in industrial cities like Faisalabad. Pahatang and Madhhuana are the two main drains passing through the center of the Faisalabad city having most of its portion unlined and utilized for the disposal of industrial wastewater [1-12]. These industrial effluents mostly consist of untreated wastewater carrying hazardous substances which were continuously leaching down to groundwater and causing its contamination [13,14]. GIS is one of the most powerful tools to visualize groundwater contamination as it consists of different geo statistics tools combined with advanced overlapping technologies and map development options which helps to study the spatial variability of groundwater contaminants
