Practice of onsite sanitation in majority of peri urban areas in India is responsible for deterioration of surface and groundwater resources. Due to inadequate sanitation and practice of onsite sanitation like pit latrines and septic tanks, the contaminant levels are exceeding permissible levels in ground water drinking sources resulting in water borne diseases, causing widespread morbidity and mortality. A field study carried out for one year in a peri urban areas of Bangalore rural district indicates that ground water sampling collected at twelve sampling stations near onsite sanitation systems are unfit for drinking purpose. Higher concentration of nitrates and chlorides in bore well water samples show that ground water is getting contaminated with onsite sanitation.

Abstract


Practice of onsite sanitation in majority of peri urban areas in India is responsible for deterioration of surface and groundwater resources. Due to inadequate sanitation and practice of onsite sanitation like pit latrines and septic tanks, the contaminant levels are exceeding permissible levels in ground water drinking sources resulting in water borne diseases, causing widespread morbidity and mortality. A field study carried out for one year in a peri urban areas of Bangalore rural district indicates that ground water sampling collected at twelve sampling stations near onsite sanitation systems are unfit for drinking purpose. Higher concentration of nitrates and chlorides in bore well water samples show that ground water is getting contaminated with onsite sanitation.
