The National Drinking Water Policy (2009) and Khyber Pakhtunkhwa Drinking Water Policy (2016) set a target of providing access to safe and sustainable drinking water supply to the entire population by 2025. Similarly, the Sustainable Development Goal (SDG) 6.0 also sets a target 6.1 “by 2030 achieve universal and equitable access to safe and affordable drinking water for all”. Monitoring of drinking water sources is crucial to ensure safe water supply, because if we cannot measure a thing, we cannot manage it. Pakistan Council of Research in Water Resources (PCRWR) in 2016 monitored drinking water quality of 25 major cities of Pakistan. Only 31% were found safe whereas 69% samples were found unsafe for drinking purpose. However, Charsadda was not part of the regular water quality monitoring program of PCRWR. PCRWR in collaboration with UNICEF conducted a detailed study of drinking water quality in Charsadda District. This report is an outcome of the study. It is hoped that it would provide a baseline towards achieving goals set in the national and provincial drinking water policies and SDG 6. vii viii SUMMARY Overall 649 water samples were collected from Charsadda District, out of those 272 (42%) were found unsafe whereas 377 (58%) were found safe for drinking. The groundwater (tube wells) is the major source of water for water supply schemes in Charsadda. Overall 158 tube wells were surveyed. Out of those, 14 tube wells were operated by TMA and all were operational, whereas 143 tube wells were under the control of PHED and out of those 64 tube wells were operational, whereas 78 tube wells were non-operational. The water samples from tube wells were found mostly safe because contaminants have less chances of access to deep layers of groundwater. The depth of tube wells in Charsadda ranged between 280 feet to 400 feet, therefore 89% tube well sources were found safe, whereas only 11% were unsafe. At consumer
