Evaluation of Drinking Water Quality in Urban Areas of Pakistan: A Case Study of Southern Lahore

Drinking water must be free from components which may adversely affect the human health. Such components include minerals, organic substances and disease causing microorganisms. A large portion of the population in developing countries suffers from health problems associated with either lack of drinking water or due to the presence of microbiological contamination in water [1]. Poor water quality is responsible for the death of an estimated 5 million children in the developing countries [2]. The problem is further aggravated by rapidly increasing population which results in poor water-quality management [3].
