I don't like my son to go in the sound for that very reason. Not only is run-off a problem, but one of the hurricanes in the past 10 years filled in a split to the barrier island that allowed the water to drain properly. Now the only two outlits to the Gulf of Mexico are over 20 miles apart and I live in the center section. Build up is nasty and residents are patitioning to reopen the pass. With that said I have used water from the gulf, but it was from out past a pier and pulled from under 5 feet of sand. Shore water is nasty and sound and bay waters are worse. I hope the report encourages some water quality improvements.
