To clarify, nowhere does it say "1 out of 28 people that go to the beach get sick". Apparently the EPA finds this to be an acceptable value-whether or not this is so, I'm not sure, perhaps someone can figure that out. And to further clarify, the '1 in 28' value is for the whole country, not SOWAL, Florida, California...everywhere, and may or may not be limited to salt water. I imagine the '1 in 28' value is analogous to the infamous minimum number of acceptable insect parts in food the Agriculture Dept. sets.
A good contact to start looking into this would be Cindy Meadows. She lives in old Seagrove-rememeber though, she does not assume office until after the runoff election.
And if anyone wants to do a little leg work, I have noticed a sewerage type odor on 395 just north of Seagrove Market area, and there is some sort of pumping house looking structure there, on the west side of the highway. Maybe it is a factor, maybe not. But if Holly Street is the epicenter of unwholesome water, this would be a potential issue.
