It's actually this way all over Florida. I wish it were only limited to central Florida. We've lived in Miami, Fort Lauderdale, Palm Beach, Lake Worth, Jacksonville...I also spend a good time on the west coast of FL (Tampa/St. Pete & Naples), and the water's nasty all over. The worst has been western Palm Beach County. The sulphur's so high, it makes your eyes water just to smell it.
You'd think after 34 years, we'd be used to it, but, no. Bottled water is the way to go in FL in my opinion -- or a good filter on your system or a Brita.
