Last Stand Information Forum:
“Water Quality – What the Experts Say”
(Key West,
FL – May 21, 2008)
Over 100
Last Stand members and concerned citizens packed the auditorium
of NOAA's Eco-Discovery Center in Key West Wednesday evening,
May 14, for a public program on near-shore water quality in the
Florida Keys.
The panel
assembled for the program by Last Stand consisted of
Monroe County Health Department’s
Bobbi Sleighter, Reef Relief’s
Mike
McCleary ,
Scott
Donahue of NOAA’s Florida Keys National Marine
Sanctuary, Assistant Key West City Manager
David
Fernandez,
and
Paul J.
Mitchell, a professional engineer and long-time
Key West resident.
Forum moderator
and Last Stand board member Amy Lachat Lynch, after introducing
the panel, gave each panelist a topic which they had been given
earlier, on which to comment.
Bobbi Sleighter,
asked to describe Monroe County’s water quality monitoring
program, told the audience there are seventeen locations in the
Keys regularly monitored, five of them in Key West. Samples are
taken on Tuesday of each week, and tested for concentrations of
fecal coliform and enterococcus bacteria, the primary bugs found
in sewage. Testing has been going on for eight years. Although
Key West’s sewage system, overhauled over several years, has
resulted in fewer “hits” (i.e. test results showing unsafe
contamination levels) than 8 years ago, unsafe levels are
observed fairly regularly at Higgs Beach and South Beach in Key
West. These “hits” are more frequent following heavy rain
events, a significant fact.
Paul Mitchell was
asked to describe how general water conditions have changed over
the several decades he’s been in the Keys. Mitchell said that
in terms of clarity and general quality, deterioration has been
“profound and dramatic”, especially in enclosed bodies of water
such as Garrison Bight, Key West Bight, and Safe Harbor on Stock
Island. He said that dredging and closing off of these bodies
had a lot to do with the worsening conditions, which have taken
place gradually over a long time. He noted that he has not
immersed himself in Garrison Bight since 2004, and isn’t likely
ever to again.
Scott Donahue was
asked to summarize water quality regulations that exist in the
Florida Keys National Marine Sanctuary. He gave a brief history
of regulations beginning in the early 1970s restricting
discharge of oil and toxic chemicals from ships, and up to the
present with the “2010 rule”, EPA’s edict that the Florida Keys
must stop discharging sewage into Keys waters by 2010. He noted
that within the Keys Marine Sanctuary, prohibitions are more
stringent in No Discharge zones.
David Fernandez
was asked to comment on Key West’s sewage and stormwater
treatment systems. Fernandez noted that at one point in 1999,
every beach in Key West was closed due to sewage contamination.
The city of Key West then embarked on a seven-year capital
program to upgrade its sewage system, and that the program was
completed in three years. Ocean outfalls of treated effluent,
previously outfalls of raw sewage, were replaced with deep
injection wells. He noted that Key West’s wastewater plant
meets stringent Advanced Wastewater Treatment standards,
exceeding minimum requirements. The city spent $67 million on
its upgrade, and citizens and businesses spent $22 million
upgrading laterals and plumbing on private property. Fernandez
noted that Key West’ system has won awards for its advanced
treatment.
He acknowledged
that stormwater collection and treatment is still a huge
problem… that during heavy rains, millions of gallons per day
flow into the ocean through outfalls as well as into injection
wells, and that stormwater contains numerous contaminants,
including fecal matter, petroleum products, all kinds of nasty
things. The city is working on its stormwater system and still
has a long ways to go.
Mike McCleary of
Reef Relief was asked to comment on No Discharge Zones and Reef
Relief’s take on what can be done to reduce near-shore water
pollution. McCleary noted that the reef is dying, partly due to
global warming, and partly due to what we are putting into the
water, both from land, and from the numerous boats and ships
that ply our waters. He noted that Monroe County has the
state’s largest number of registered boats. No Discharge Zones
were extended in 2002 to include all state waters within the
National Marine Sanctuary, but that the jury is still out on
their effectiveness. He also said that cruise ships discharge
up to 30,000 gallons of waste (treated and untreated) per ship
per day, but that they’re prohibited from doing so within 3
miles outside of state waters. He said that No Discharge Zones
need to be expanded to include federal waters, which extend
farther offshore. Some discussion of cruise ship discharges
ensued, with Key West Ports Director Ray Archer commenting that
cruise ships in general voluntarily refrain from discharging
waste within 12 miles of shore. Discussion included the
possibility of requiring cruise ships to pump out into a city
facility to avoid ocean dumping, but Fernandez noted that such
pumpouts would far exceed the capacity of Key West’s waste
treatment facility and would require storage capacity that does
not exist.
Following the
panelists’ comments on the above topics, the audience directed
questions to the panelists. Among other things, people wanted
to know:
-
why Fort Zachary Taylor consistently shows only low
levels of contamination, the reason being that there’s good flow
of water past that point, and that there’s no stormwater
discharge near there.
-
what kind of testing is used to distinguish between human
sewage sources and that of animals, the answer being that DNA
testing has shown that some is from humans, and some is from
other creatures, including domestic pets, wild animals such as
sea birds, and that more can be done to contain contamination
from some sources than from others.
-
why does it even matter whether contamination is from
humans or animals, since it’s all pollution; the answer is that
different types of bacterial contamination are handled by
different systems, human sewage in the sewers, and most animal
sources are in storm runoff.
-
why we don’t re-use treated wastewater since it’s treated
to Advanced Wastewater Treatment (AWT) standards; the answer is
that re-use of treated water is likely feasible for some
uses, but treatment doesn’t remove all contaminants (e.g.
pharmaceuticals and other contaminants) and therefore isn’t safe
for drinking.
-
what the extent of contamination is in bottom sediments;
it was noted that a variety of contaminants are present in
sediments that settle on the bottom, including heavy metals such
as lead, copper, arsenic, and that activities such as dredging,
and stormwater runoff can re-suspend contaminants in bottom
sediment.
-
why, if some cruise ship ports have enacted their own
standards more strict than federal standards, Key West isn’t
willing to (Monterrey, California was cited as an example);
there seemed to be no answer to that question that was
satisfactory to the audience. It was stated that the cruise
industry is “working in the right direction”, but not everybody
was satisfied by that.
-
what the status is on modifying rules to allow old septic
tanks to be converted to cisterns for use in storing water for
irrigation of plants, etc. The answer is that modifying those
rules “is underway”.
-
what the single worst source of contamination is;
overwhelmingly, all panelists stated that stormwater is the
single worst source. (It should be noted that stormwater is
only the vehicle for contaminants’ reaching the water;
each contaminant still has an ultimate source, but that
was not mentioned.)
-
why North Stock Island’s wastewater isn’t treated by Key
West’s AWT system; the less-than-satisfactory answer was that
Stock Island has an “approved” system, begging the question.
-
why wild birds’ waste can’t be collected; the answer is
that they are wild, and that we can’t eradicate wild birds nor
diaper them.
-
what can be done to reduce contaminants in stormwater;
some measures that can be taken include picking up pet waste,
maintaining vehicles so they don’t leak oil, care in disposing
of wastes such as oil, antifreeze, etc, reduction or elimination
of lawn fertilizers, etc.
-
why tests at Higgs and South Beach consistently show
higher levels of contaminants; because they are near stormwater
outfalls.
From the
thoughtful questions posed by the assembled citizens, it was
obvious that the residents here are very concerned about water
quality, and demand that local policymakers become even more
concerned than they are. It is clear that if places like
Monterrey, California can enact and enforce standards more
stringent than minimum federal standards, there is significant
local support for our local and state governments’ doing so. |
