This document provides an update on the study being conducted during in Biscayne National Park on glyphosate applications to near-coastal aquatic environments. Because of the heavy use of glyphosate formulations to control unwanted vegetation along canals and structures in South Miami-Dade County resources in areas of Biscayne National Park adjacent to the water control structures could be at risk due to the presence of the active ingredient or the surfactants used in commercial formulations. For that reason, the main purpose of the initial phase of the project was to conduct a detailed survey of canals and coastal environments where glyphosate is applied as vegetation control herbicide concentrating in the following objectives: a) Occurrence of the parent herbicide and metabolites; b) Spatial and temporal distributions; c) Potential accumulation into marine and limnetic sediments. The original SOW was modified to reflect changes in funding so that only 1/3 of the proposed work will be conducted on the initial phase (Year 1) with the remaining 2/3’s to be conducted in the second funding cycle. In addition, at the request of the Park Leader a comprehensive survey of other contaminants such as pesticides and herbicides was required as part of an initial baseline assessment of the study area.
