Actually, at the behest of a coalition that included the Chamber of
Commerce and Reef Relief, the voters in Key West approved extra taxes via
referendum to install an advanced nutrient-removal sewage treatment plant
with a deep well backup.  This was several years ago and the plant has been
functioning well.  The Keys plan to upgrade sewage treatment has been
underway for many years in population centers such as Marathon, Islamorada,
Key Largo and Big Pine,  mainly due to a state mandate to upgrade or risk
losing development points (rights) from the state as part of comprehensive
land use planning.  As noted, funding has been the pinch point. Many
illegal cesspits have been phased out as well and a no discharge zone has
been established Keys-wide.  In my opinion, though it may be too little too
late, it is still important to complete the plan to upgrade treatment in
the Keys to improve water quality, not just for the corals, but also
because fecal contamination is a human health threat. Ear infections are a
fact of life for frequent Keys divers.  All the best, DV
