G.7 INFORMATION COLLECTION SUMMARY REPORT Executive Summary The South Florida Water Management District (District), Florida Department of Environmental Protection (FDEP), Collier County, and other local stakeholders have formed a Working Group to conduct this Picayune Watershed Water Quality Feasibility Study (Study) to address increased nutrient inflows for primarily Total Phosphorus (TP) and Total Nitrogen (TN). This will be accomplished through identification of potential treatment technologies based on a review of literature and other information identified by the Working Group. The Information Collection Summary Report presents the results of review of documents, web links and other information provided by the working group. The report also includes detailed descriptions of the nutrient treatment technologies found in the reviewed information and provides general recommendations regarding which technologies to focus on during the Task 4 Feasibility Study task that will follow this report. This document summarizes the review of information provided by the Working Group, focusing on technologies identified within those resources. Overall, a total of 19 treatment options are described in detail within this report. Eleven proven technologies in common use were identified in numerous documents and are included as ‘Applicable’ project types below, including constructed treatment wetlands, detention areas and settling ponds, spreader swales and berms, restored wetland systems, air diffusion systems, the growth and removal of periphyton and submerged aquatic vegetation (SAV), polishing ponds, hybrid wetland treatment technology, bioreactors, iron enhanced sands, and Bold & Gold® filtration media . Eight additional ‘Non-Applicable’ technologies are described below because they were identified in the reviewed documents as potential technologies for nutrient removal in previous South Florida studies. These include novel concepts that have generally only been demonstrated for smaller scale systems, including recyclable water containment areas, algal scrubbers, alum treatment systems, floating treatment wetlands, NutriGone MediaTM, Downstream Defender®. Aquifer storage and recovery (ASR), and deep well injection. Although these technologies appeared in the reviewed literature, none of these are recommended for additional consideration. It is recommended that the Applicable treatment options be considered for further evaluation under the Task 4 Feasibility Study, possibly combining multiple technologies into a treatment train. It is also recommended that the operation and maintenance of treatment systems chosen for further investigation consider a sediment and or vegetative removal component.
