Eliminate Land Applications of Residuals - FDEP
End the practice of depositing domestic wastewater residuals on land, which can result in excess nutrients getting in tributaries and estuaries
Residuals Contain Nutrients that are land applied in Phosphorus-Sensitive Basins
![Page 21: Water Resources Advisory Commission Lake Okeechobee Committee January 25, 2006 Susan Gray, Ph.D](https://reader036.vdocuments.us/reader036/viewer/2022070410/56649eff5503460f94c14c64/html5/thumbnails/21.jpg)

Progress
Between 1998 and 2005, more than 35 projects have been completed in the north watershed.
Approximately 20 additional projects are under way and expected to be complete in the next one to five years.
Will prevent an estimated 150 tons of phosphorus from entering the Lake each year.
Will add approximately 280,000 acre feet of additional water storage to reduce impacts from flood-control releases to the estuaries
