Question

5 which is a point source of water pollution? a discharge pipes b runoff from farms c runoff from construction sites d runoff from urban areas

Explanation:

Point source pollution is pollution that comes from a single, identifiable source. Discharge pipes are a single, identifiable source of water pollution. Runoff from farms (non - point source as it comes from a large area), runoff from construction sites (non - point source as it is from a broad area), and runoff from urban areas (non - point source as it is from a large, diffuse area) are non - point sources as they come from large, diffuse areas rather than a single, identifiable point.

Answer:

A. discharge pipes
