Question

What sources of water pollution include industrial waste, agriculture and sewage

Answer 1

The biggest source of water contamination is industry in general if you meant a "point source"

Answer 2

Primary sources

Step-by-step explanation:

Primary sources of water pollution are those wastes that are discharged into bodies of water directly from the sources that produce them, as is done with industrial wastes, agriculture and sewage. This type of pollution greatly damages marine life, diminishing biodiversity, degrading nature and making it difficult for people living on fishing and other activities related to this environment.
