Cows, sheep, dogs, etc.
It may not be human, but there's still a heck of a lot of fecal matter in rivers.
Fish wee in them, too

we were always told ( before the Eastney outfall was extended offshore etc ) that you don't swim of Eastney - you just go through the motion.....

Good afternoon:
I have watched threads on the subject of waste discharge from yachts for a number of years and have been amused at the "alarmism" that develops as the thread progresses. I recall reading one several years ago where the poster claimed the surface of the bay was covered by large lumps of waste after a gulet had discharged a holding tank. There is a comment above about lumps as large as walnuts floating on the surface.
I think it is time to put this matter in perspective and would like to provide a quote from another site:
Feces, also spelled faeces, also called excrement, solid bodily waste discharged from the large intestine through the anus during defecation. Feces are normally removed from the body one or two times a day. About 100 to 250 grams (3 to 8 ounces) of feces are excreted by a human adult daily.
Normally, feces are made up of 75 percent water and 25 percent solid matter. About 30 percent of the solid matter consists of dead bacteria; about 30 percent consists of indigestible food matter such as cellulose; 10 to 20 percent is cholesterol and other fats; http://global.britannica.com/science/feces
While I don't want to admit to the same fascination that some young children exhibit towards what they leave behind during potty training I have often gone on deck to check the results after pumping my toilet and have only observed a fairly large "cloud" of brown water which quickly dissipates. I do not recall ever having observed any "lumps" other than undigested kernels of corn and don't understand how anything else could get past the toilet "joker" valve without being broken/mashed up.
While I understand the concerns of most yachtsmen/women to deal with this subject as responsibly as possible under the circumstances I do wish there was less exaggeration in some of the posts - after all how much damage can the substances outlined above in the amount mentioned do in a bay containing millions of gallons of water?
If this were the Daily Mail I would expect lots of red arrows but fortunately this is not the Daily Mail and I hope that future posts on this subject will deal with the subject a little more realistically.
Cheers

Firstly it's all about multiplication: numbers of people and numbers of boats. With plenty of tidal movement you don't have to do your integration over long times.
Do you prefer your juice smooth or with bits in?

As with most things in life it's all about how much and how often. I don't think a lone yacht in an isolated anchorage is going to make the slightest bit of difference to anything, a whole load of house boats in a residential marina moored so close together they have effectively cut off the tidal flow is another matter altogether, especially if high tide falls about 3pm on a lovely sunny afternoon with a slight onshore breeze......
