The city of Orlando, Florida, and surrounding areas have used drainage wells to alleviate flooding and to control lake levels since 1904. In the greater Orlando area of about 75 square miles, about 310 drainage wells are presently injecting an average of approximately 23 million gallons a day of surface water into the Upper Floridan aquifer, a zone of high transmissivity approximately 350-feet thick. Some of the drainage wells were also used to drain effluent from large community septic tanks and various industrial wastes from processing plants until the 1950's. A 3-year study, from 1987 through 1989, encompassed about 6 square miles in the downtown urban area of Orlando and included water-quality analyses from wells influenced by inflow from one or more drainage wells. The water-quality data from the urban area were summarized and compared to water-quality data from wells in the Orlando area but upgradient from the urban study area and in the Ocala National Forest area about 50 miles north of Orlando.
