camaraderie Fast...I think what you posted is the reason we want no dumping in areas WITHOUT significant tidal flow. When there is NO rise in fecal coliform levels DUE to tidal flow...then it follows that there is no need to prohibit dumping.
This would apply to dissolved oxygen levels as well since there would be no depletion and the balace of the aquatic environment would not be affected by the normal decomposition of "waste products".
For relatively enclosed situations...with high concentrations of boaters and little tidal exchange...then regulations are appropriate.

Problems resulting from fecal contamination of water

Human health hazards

Large quantities of fecal coliform bacteria in water may indicate a higher risk of pathogens being present in the water. Some waterborne pathogenic diseases include ear infections, dysentery, typhoid fever, viral and bacterial gastroenteritis, and hepatitis A. The presence of fecal coliform tends to affect humans more than it does aquatic creatures, though not exclusively.

Effects on the environment

Untreated organic matter that contains fecal coliform can be harmful to the environment. Aerobic decomposition of this material can reduce dissolved oxygen levels if discharged into rivers or waterways. This may reduce the oxygen level enough to kill fish and other aquatic life. Reduction of fecal coliform in wastewater may require the use of chlorine and other disinfectant chemicals. Such materials may kill the fecal coliform and disease bacteria. They also kill bacteria essential to the proper balance of the aquatic environment, endangering the survival of species dependent on those bacteria. So, higher levels of fecal coliform require higher levels of chlorine, threatening those aquatic organisms.

RickBowman Wow, I never knew I had it so good. In the Great lakes, we don't dump overboard. Get caught doing so and you could have up to a $100,000 fine, lose your boat and maybe your freedom. It cost me $5.00 US to have my 15 gallon tank pumped out, half filled with fresh water and pumped out again. $5.00? No complaints here. There are pump out stations at every harbor that I have ever visited. Then a honey dipper truck will come and pump it out from the marina holding tank and transport it to a local refinery, yummy yummy right here, or sometimes to a farmers field, please wash all of your vegetables. No such thing as a 3 mile limit in the Great Lakes. It's all very simple, and I like it.

Quite an interesting thread. It degressed for a bit. One thing I will never do is name call or attack another persons country in this forum. It cheapens us and sailnet and imho is not what this is about. No matter what country we are from, and what I have gathered are many, we all have our great qualities and not so great qualities. We are all human and we all have the same basic needs. To eat, sleep and sail. ViVA' Le Broadreach!

By most standards, I would be considered an "eco-freak", because I compost, use CF lights, don't own a car, have only one kid, etc. But in reality, it's because I'm a cheap bastard who would rather spend boat bucks than drive an SUV for 10K a year in gas, insurance and depreciation. The stupidity of a polluting lifestyle comes into it, but the economy of just not wanting "stuff" pushes that decision.

This plays into your point this way: There have been several climate events we know of (the rapid rise in sea levels around 7,800 BC, the "mini Ice Ages" of the Medieval period, and so on) where fairly severe changes have happened comparatively suddenly. Mankind's response was to die in large numbers....historically a typical coping mechanism. So while it's true that we can't cope well with solar dimming or volcanos putting a billion tons of soot into the atmosphere, I prefer to err on the side of caution myself, because I suspect that mankind's industrial activities are playing a fairly significant part in (likely) worsening or hastening climate change, and that certain of our industrial excreta of choice (CFCs, NO, various other weird gases) haven't existed in nature, and thus comprise uniquely introduced "wild cards" that could tip rapid climate change either way.

So it's cheaper and latterly more responsible for me to not have a car and to attempt to reduce that carbon footprint as much as possible. I truly believe that if I don't go long-term cruising in the next ten years, the impact of climatic change will alter parts of the world that I will "miss out" on seeing some real beauty.

But as for the pooping, I find it stupid as well. Yachties comprise a tiny, but visible and mostly friendless (thank you, envy!) target. Freighters pump out bilge water full of zebra mussels and goby fish from distant parts directly into the Great Lakes in amounts that surpass the lifetime pump out of ten yachts in every bilge transfer. In Halifax and Victoria, toilet crap goes directly into the harbours. New York has produced vast seamounts of crap and garbage.

So while I find the hypocrisy as noxious as the sludge, I will be a good little citizen until I get offshore, where I will continue to leave packaging ashore, crush cans and crap off the side with a clear conscience.

Finally a voice of reason....

Hear, Hear! Once again I must compliment you on your considered appreciation of the issue at hand. Cheers!! M6

camaraderie Stout...
1. The people on the beaches don't like human waste floating by...and they think porpoise crap is "cute" (I agree with you but the landlubbers outnumber us!) I especially think that we ought to be able to use processing heads that discharge cleaner "product" than local sewers are permitted to.

2. Global warming discussions are probably best located in the off topic forum. Lots of "heated" debate there.

stoutwench I have two very simple questions that will help me understand the two topics in this thread:

1) What, specificly, is wrong with untreated human waste being dumped in an area with significant tidal flow? Does it not break down in the same manner as fish or bird feces. What harm does it cause? Please, no general terms like "it is pollution". I'm looking for the scientific answer.

2) There have been numerous global climate changes in the past, but didn't they take thousands of years to occur? Is it not possible that global warming is being caused by a combination of natural and man made influences?

camaraderie We thank god you're a Canadian too Jimmy! ....but you COULD move further away!

jimmyb116 All I can say is thank god I am a Canadian, If SURFESQ is any example Its no wonder most of the countries I have visited arenít to crazy about Americans. I am embarrassed to live next to you. Did you by chance vote for your current President ?

Whampoa Camaraderie, good evening. Thanks for the positive comment. I placed a number of pics of Whampoa out in the member gallery. Hope you enjoy them as much as I do. Regards, John
