Question

Untreated human excreta is a health hazard. Explain.

Answer 1

• Human excreta are home to several pathogens and disease-causing microorganisms. If left untreated, it poses a concern to public health.
• Many water-borne diseases, including cholera, diarrhoea, typhoid, polio, meningitis, hepatitis, and dysentery, are transmitted via the faecal-oral route. Untreated human excreta can pollute water and soil.
• Both surface water and groundwater become polluted. Groundwater is the primary supply of water for wells, tube wells, springs, and many rivers, making it the most prevalent pathway for water-borne diseases.
