"Green and sustainable remediation can be further environmentally friendly by using renewable energy systems in place of utility-provided power. This project includes the installation of a single-axis tracking photovoltaic (PV) array at a former dry cleaning site that is undergoing remediation under the Missouri Department of Natural Resources (MODNR) Dry cleaning Environmental Response Trust (DERT) Fund program. The PV array provided power to a positive displacement piston pump that extracted ground water from a 15 m deep monitoring well. The tetrachloroethene (PCE)-contaminated ground water was treated using granular activated carbon (GAC) units prior to discharge to the local publicly owned treatment works (POTW). The system included a linear current booster that eliminated the need for batteries but meant that the system would only operate at or above a solar radiation threshold. A datalogger continuously collected radiation, flowrate, and electrical data, and water quality samples were regularly collected to quantify the mass of PCE and PCE-associated products that were removed from the aquifer. There were several challenges encountered during the project, the greatest of which was the low aquifer yield and competing remediation activities. Still, a stochastic analysis was performed to estimate the average daily flowrate for any given month. A long-form model analyzed the flowrate as a function of the power consumed by the pump, with consideration given to the renewable, electrical, and mechanical energy transformations. A short-form model was also analyzed where daily flowrates were solely a function of daily observed radiation. Radiation data was obtained from a publically-available resource and compared to the actual observed radiation. The project provides means for predicting PV-powered pumping performance at other sites"--Abstract, page iv.
