Question

Digging wells deep into the ground is not considered safe for health. Why?​

Answer 1

Answer:

If a well is located far enough away from a latrine, the soil is able to filter out harmful organisms before they reach the well. To determine the minimum safe separation distance between latrine and well we need to know three things:

1. Direction the groundwater is moving.

2. Distance between the bottom of the latrine and the water table.

3. Type of soil between the bottom of the latrine and the water table.

Thanks for the question.
