Most soil and groundwater treatment remediation systems are power-hungry units that require their own electrical power drops. Occasionally, opportunities arise where a greener choice can be made. This was the case with Broward County’s Partnership for the Homeless Center, where an inadvertent diesel fuel spill from an emergency generator adversely affected the underlying soil and groundwater, and free floating product (FFP) was also found on the water table as a result of the spill. We were tasked to remediate this issue. A solar-powered FFP recovery system was implemented to capture the FFP from the groundwater’s surface. This system successfully operated for six months and recovered approximately 450 gallons of diesel fuel, after which no additional FFP was detected. Choosing solar power seemed to fi t the property’s sustainability environment since most of the patrons travel by either bicycle or foot. After the FFP was removed, the remaining diesel fuel impacted soil and groundwater could be effectively treated, and when the subsequent remediation system was selected. Once again, we implemented solar power technology with the aerobic bacteriological treatment. The system has proved to be extremely effective and our scientists are very pleased with the results..
