Stage 1. Site Selection, Preliminary Water Testing, Construction of Pilot. In Stage 1 we will work with the County to identify appropriate sites for the pilot along the NRC and to secure the permits for construction of the pilot. To date, we have al- ready made progress on this front and worked with Indian River Farms Water Control District to identify an acceptable site and to secure a letter of support for the project from an adjacent HOA community. We will collect baseline water quality data and data on suspended and settleable solids in the NRC. A detailed breakdown of the sampling schedule and test parameters is available upon request.Sample analysis costs were calculated based on comparative quotes from two laboratories that are National Environmental Laboratory Accreditation Program (NELAP) certified. Note that we have budgeted for a percentage of quality control samples (field /equipment blanks) that meets or exceeds FDEP field quality con- trol requirements (5% of samples as per DEP-SOP-001/01). The Stage 1 data will be used to guide Stage 2 and Stage 3 pilot operations and, potentially, modifications to the pilot design (eg., flow rates, incorporation of clarifier, etc). In the Stage 1 budget, we allotted funds for a small scale lamella clarifier' to allow col- lection of a sufficient amount of suspended solids to perform a robust chemical analysis on the material. (Our preliminary spectrophotometric and Imhoff cone data suggest that we will need to pump and settle several thousand gallons of water to generate sufficient dry suspended solids for chemical analyses). An additional benefit of purchasing this unit is that it can be used as a clarifier module, as required, during Stage 2/3. During Stage 1 we will purchase equipment and materials, construct the pilot system and bring electricity to the site. Based on budgetary considerations and discussions with the County, we will be using modular tanks for pilot construction; the specific construc- tion materials and costs are available on request. The general layout of a LEAPSTM test system is illustrated in Figure Al on the next page and is similar to the designs previously described in our Proposal (page 23, Figure 213). However, we will now only operate a single LEAPSTM system that contains Water Lettuce as the floating aquatic plant; as opposed to testing multiple LEAPSTM systems with different floating aquatic plant species. This modification in scope will allow us to conserve and reallocate funds to extend the project period from six months to one year. Further, it reflects the field -reality that Water Lettuce is the overwhelmingly dominant floating plant currently in the NRC. The floating aquatic plant module for the pilot LEAPSTM test system will consist of two serial 725 gallon tanks to maximize treatment area, hydraulic detention, and solids set- tling capabilities. The next module, the periphytic, ephiphytic algae reoxygenation (PEARO) system will be constructed as described in the original Proposal. The emer- gent plant module will consist of a 725 gallon tank that incorporates 3 rows of BEEMATS floating growth structures; this will allow us to evaluate three emergent spe- cies side-by-side and gives us flexibility in plant harvesting strategies. 1 The clarifier is a LYNTEK 10 gallon per minute lamella clarifier tank (60 gallon settling tank) 266
