Benthic Monitoring for the Florida Keys Canal Water Quality Remediation Project

Many residential canals in the Florida Keys are unhealthy with low oxygen levels, murky water, and harmful chemical conditions that have resulted in waters unsuitable for swimming and many sea critters. To fix these problems the US-EPA, Monroe County, cities within the Florida Keys, and even homeowner associations are helping to fund restoration efforts. The first stage of restoration includes the experimental installation of remediation technologies that could potentially improve canal conditions. Those technologies that are the most effective and cost-efficient can be installed in more canals across the keys. This first stage will assess the effectiveness of the different technologies by comparing canals with installed technologies against nearby, unaltered controls over a period of three years. The effectiveness of remediation technologies will be determined by using organisms, including seagrass, macroalgae, and fish that are commonly used to judge water quality in south Florida. We are also taking sediment samples to understand the source and composition of the accumulated organic material in the canal bottoms. Check out our work in the demonstration canals mapped below or visit the Monroe County's website on the project.

We have recently added six canals in Islamorada to our monitoring. These will be monitored as sewage changes from septic to municipal sewage.
