The major difference between point and nonpoint pollution sources as far as water pollution is concerned is the number of sources of pollutants.

Point and nonpoint sources of pollution

Point source pollutions are pollutions in which the source of the pollutants can easily be identified. This is so because they are usually from a single sources.

Nonpoint source pollutions have their pollutant sources all over the place and this makes it difficult to pinpoint a particular source as to where the pollutants are coming from.

Hence, the difference is majorly in the number of sources.
