As I said in my earlier post, "it's hard for coral reefs to flourish in a
I didn't get much response from the list about this issue, but I believe
it's the major issue that needs to be solved in order for coral reefs to
Specific to Kauai, in my opinion, there are numerous problems related to
"Water unsafe at Kikiaola boat harbor" Dec-2010
I doubt things haven't changed much since this article.
Take a look at Kauai using Google Earth. You'll see that there's a
significant agricultural industry on the island producing mostly sugarcane
probably. And you can see the runoff from the rivers and plumes of dark
water at the mouth of these rivers running into the ocean. I'm sure the
runoff contains significant amounts of pesticides and is heavily laden with
fertilizer nutrients. It's no wonder why the reefs suffer.
I have been SCUBA diving some of the reefs of Kauai. The reefs are very
close to shore. I would say the reefs are within a half a mile of shore
because the island drops off quickly into a very deep blue water. BTW,
there are a lot of "Frog fish" on these reefs.

according to the article. Honolulu, Oahu had been exempt from having to do
secondary treatment of their wastewater.
"Oahu's four main outfalls are off of Sand Island, Mokapu, Barber's Point
and Waianae. In 20 years of research, "We've never been able to determine
any negative effects on the life around the outfalls," says Philip Moravcik,
technology transfer specialist for UH-WRRC."
I doubt if Kauai, as a higher standard for wastewater treatment than a Oahu.
As a follow-up to my original post "it's hard for coral reefs to flourish in
a toilet bowl". Here's a video you might want to take a look at:
Florida's Chapter 2008-232, which mandates the elimination of the South
Florida wastewater outfalls by 2018 is great, but I doubt the State of
Florida will meet this deadline. Check out this video, which illustrates
the magnitude of the problem:
The most amazing part of this video is Miami-Dade's mayor asked the State of
Florida not to implement this law eliminate these outfalls because it may
raise everybody's water bill by 20 bucks.

Bastian, you may be referring to the work done by Jim Porter and others,
where they found a link between white pox, which decimated the elkhorn coral
populations in the Keys, to a bacterium found in the human intestinal tract,
the bacterium was present in the influent waters at the treatment facility
but not present in the effluent. Stormwater runoff is a big problem in the
keys, key west alone has over 970 storm drains, where the water drains
directly to the ocean, I dont know what kind of sewage treatment
infrastructure is on Kauai, but yes I would think it certainly is a
possibility good luck, Rudy
we also have a problem with septic systems in the keys as well, old and
