AN ASSESSMENT, IMPACTING OF 2022 HEAVY RAINFALL ON GROUND WATER QUALITY IN TALUKA KHAIRPUR, PAKISTAN

Abstract

Groundwater is the primary source of  Fresh water,  plays a central role in sustaining life and livelihoods in Taluka Khairpur, where the quality of groundwater may significantly impacted due to increased surface runoff, infiltration of contaminants, and water table fluctuations. As groundwater is a source for drinking and irrigation in the region, potential changes in its quality pose risks to public health and agriculture. However, no detailed assessment has been conducted to evaluate the extent and nature of these impacts, creating a critical gap in local water resource management. of drinking water, agricultural irrigation, and household usage. However, with recent shifts in climatic conditions particularly the increased intensity and unpredictability of heavy rainfall events the safety and quality of this vital resource are under growing threat. This research aims to assess the impact of heavy rainfall on groundwater quality by conducting a comparative analysis of pre- and post-rainfall water samples collected from various boreholes and hand pumps across Taluka Khairpur, with a focus on identifying potential contaminants, evaluating the risks, and informing sustainable water resource management practices. Through a comprehensive analysis of groundwater samples and hydrochemical data, this research will provide critical insights into the effects of heavy rainfall on groundwater quality and contribute to the development of effective strategies for mitigating these impacts and ensuring the long-term sustainability of water resources in the region.
