Abstract
ABSTRACTPit latrines are projected as a safe method of excreta disposal without considering its potential impact on groundwater contamination. To understand the possible link between pit latrines and groundwater quality, two villages using pit latrines and groundwater were purposely selected in Khyber Pakhtunkhwa, Pakistan. In the targeted villages, the numbers of pit latrines and groundwater wells, their depth, subsoil strata, distance between them, year of establishment, and design were determined. Drinking water samples from the two villages (Kot and Takht-e-nasrati) were collected and analyzed for coliform, nitrates, and nitrites. Groundwater contamination in both villages was confirmed possibly due to pit latrines, particularly in the permeable soil profile. Also, it was observed that local communities are often ready to take remedial measures once they understand the potential link between pit latrines and groundwater contamination and the associated health risks.
