Evaluation of SHORE Monitoring Stations in the Context of Nutrient Compliance Targets in Florida Keys National Marine Sanctuary

​

"Water quality sampling since 2008 throughout the Halo Zones of the Keys, shows that for one parameter, samples complied only 22.3% of the time; for the other parameter, samples complied 58.1% of the time."

Comments by Licensed FL Geologist

​

"These tests demonstrate that in the karst geology of the Florida Keys, shallow sewage well injection
is the functional equivalent of a direct discharge to surface waters."

Affadavit - Effect of Nutrient Addition on Marine Ecosystems of the FL Keys

​

"..the plants and animals ... of the Keys – the seagrass and corals – are quickly killed and replaced by fast-growing, noxious seaweed if nutrient delivery is increased."

2018 Update to the Florida Keys Reasonable Assurance Document, EPA

​

"Throughout the Keys, all of the areas within the Halo Zone waters (up to 500 meters offshore)... are impaired for nutrients...." “The Florida Keys are a linear collection of small watersheds which are hydrologically connected at the local level
by near shore waters.”

​

"First we documented elevated nutrient concentrations (DIN, TN, TP, and SiO2) in waters close to shore along the Keys.

These changes, associated with land/human development, have become even more obvious by the addition of 10 stations
located very close to shore..."

Design and implementation of dye-tracer injection test,
Cudjoe Key, Florida Keys, Final Report, 2014

​

"We conclude that ... injected freshwater at the current injection depth of 80’ to 120’... readily migrates ... to surface waters. These results are similar to those found by other researchers elsewhere in the Florida Keys."

​

"Long-term (1995-present) trends show changes in the region’s seagrasses consistent with decreasing water quality and increasing nutrient availability... our indicators of Sanctuary-wide status have rebounded, but these rebounds do not include data from very-near-shore sites."

Excerpt - Black and Vetch Memo for Cudjoe Wastewater Treatment Plant

​

"FDEP... stated that most shallow wells in the Florida Keys are only operational when the tide is receding.

FDEP cited several plants with shallow wells that do not work."

of the Florida Keys

Limestone in the Florida Keys is "extremely porous and permeable due to conduits and interconnected pore spaces
created by ancient coral growth and meteoric diagenesis."

Sewage pollution in Negril, Jamaica: effects on nutrition and ecology of coral reef macroalgae

​

"Globally, escalating nutrient pollution and eutrophication have led to an increase in the frequency and intensity of harmful algal blooms. One mechanism causing HAB outbreaks is increasing nutrient concentrations and alteration of N:P ratios from increasing sewage pollution."
