B -- STUDY AND TEST VARIOUS SUBSTRATES FOUND WITHIN STA-1E TEST PROJECT, WEST PALM BEACH COUNTY, FLORIDA SOL DACW17-00-R-0042 POC Brenda L. Martin, Contract Specialist, (904)232-3820 E-MAIL: click here to contact the contracting officer via, brenda.l.martin@saj02.usace.army.mil. The Jacksonville District Corps of Engineers proposes to establish a sole source cost reimbursable contract with the Southeast Environmental Research Center (SERC) located at Florida International University (FIU) in Miami, Florida. The purpose of this effort is to provide technical information needed to implement a new technology at a full scale Corps project. The contractor is expected to conduct the necessary investigations and provide the Corps with sufficient technical information to meet this purpose. The technology is referred to as Perphyton Stormwater Treatment Area (PSTA). PSTAs are designed to remove high levels of phosphorous from agricultural runoff water. Levels attained are near those found in natural Everglades systems. The Corps is in need of a protocol by which we can scale-up from a small experimental procedure to a large operation system. This work is critical to our mission in south Florida. SERC is a not-for-profit research center, within the State University (Florida) system (a State Agency) devoted to conducting environmental and wetlands research in south Florida. SERC has established and developed its environmental laboratory and specialized staff to study the Everglades and has achieved international recognition as a leader in the area. It maintains and operates unique research and testing laboratory facilities directed at Everglades and South Florida research adapted to the study of various ecological processes that define the bio-geo-chemical cycles of this unique region. SERC has innovated and developed new techniques to study phosphorous levels just above detection levels (DTL). The SERC laboratory infrastructure is based on the latest state-of-the-art customized analytical equipment and analytical methods specifically devised to study phosphorous uptake in periphyton algal communities. This contract requires SERC to study and test various substrates found within the STA-1E footprint to determine the optimum conditions needed to nurture the appropriate periphyton community found naturally within the Everglades. SERC shall provide an experimental plan which includes the purpose, concept, order of work, schedule, cost estimate, and end products. SERC shall also test the operational ranges of this periphyton community to determine the feasibility of using this technology to reduce phosphorous, within naturally occurring hydraulic regimes and hydroperiods. SERC shall summarize the operating parameters needed to achieve the lowest practical level of phosphorous in the system. Data generated shall be summarized on a quarterly, and annual basis. Formal reports shall be provided annually which will include material balances of key parameters, such as phosphorous, dissolved oxygen, sulfate, total organic carbon, mercury, nitrates, such that sufficient data is available to perform scale-up design.
