Question

Which is not a major source of groundwater pollution?


sewage


compost


chemicals


pesticides

Answer 1

Among the options listed, **compost** is not typically considered a major source of groundwater pollution. Sewage, chemicals, and pesticides can all contribute significantly to groundwater contamination. Compost, on the other hand, is generally used as a natural fertilizer and can improve soil health when used properly, although it could potentially contribute to pollution if improperly managed.
