But I would expect that the cowpies in the proper pasture not connected directly to a waterway would have nowhere to go.
As the cowpie dries and disintegrates with the weathering, I would expect only a sheet flood would provide the contamination overflow that you describe.


It is the sheer concentration and overload of too many animals (humans) per acre, and poor to disgusting animal husbandry practices, that creates the inability for nature to cope.

Bill,
The survivability of enteric (GI tract) bacteria has long been thought to be problematic as you said in sunlight, etc. The problem is that when released into surface waters or spread on the ground, the bacteria are not washed individual bacterium into the water. They reside in yuckie clumps of organic stuff (cow pies, et al) and this will float away nicely protecting the bacteria incased in this. Sunlight and O2 has a hard time doing the job. This is the same reason why UV light that has been tried as wastewater treatment technology, does not live up to its potential in the "real world"


On the other hand you haven't lived if you haven't gone barefooted in a pasture. Squishes up between your toes in a pleasant way when they are fresh and if you're 6 or 7 years old. Trouble is today with mega poop farms and factory production, there isn't much pasture to enjoy.

Regards,
Chuck.
