Groundwater Contamination: A Brief Review for Pakistan and Saudi Arabia
This study presents a brief review on groundwater contamination, its causes and effects. The groundwater is contaminated by various sources. However two major sources, domestic sewage and industrial waste are discussed. The improper management of domestic wastewater and industrial effluents is responsible for deterioration of groundwater quality and human health hazards. The status of groundwater contamination in major cities of two countries Pakistan and Saudi Arabia is discussed. Both countries are suffering from groundwater contamination issues. In Pakistan most of population is deprived of clean drinking water because of contamination of groundwater water reserves. There are close similarities between Saudi Arabia and Pakistan as far as the contamination and the constantly declining quality of groundwater is concerned. The colossal amalgamation of wastewater from domestic and industrial sources with groundwater resources is causing a concentration of hazardous substances, like heavy metals, which eventually leads to poor human health Issues. It's the dire need of the hour that the water reserves left underground should be saved from being contaminated.
