like humans carry it. Not shure about whales. Either way i think the ecoli would not last long in the cold water.

In and of itself, ecoli is pretty harmless. They use it as a marker since it's easier to develop tests to find it.
But your point about temperature is spot on. Most pathogens need something pretty close to body temperature to survive for any length of time.
Think about this:
- If you dump 3 miles off shore, it's likely going to be at least a couple hours before any of the waste gets near a beach and if you are talking 70-80 degree water temps most pathogens will be long dead.
- If you use the hot shower
in the marina bath house right after someone else, any waste that got on the floor is likely to be splashed onto you within minutes while incubating in a warm moist environment
Your odds of picking up something in the shower
is orders of magnatude higher but we don't outlaw showers in the name of safety
Employing reasonable rules in areas where people are likely to be in contact with the water makes sense. Plus there is just the gross factor. Making large bodies of water no discharge zones is a stupid knee jerk reaction.
