Joe's Creek Stream Restoration Utilizing Phosphorus Mitigation and Realtime Variable Rate Injection and Monitoring Systems

Pinellas County is invested in improving Joe’s Creek water quality so local urban communities can enjoy outdoor recreational opportunities centered around safe, clean, and enjoyable water. This project involves coupling innovative chemical application and monitoring approaches to remove Phosphorus (P) within the waters of Joe’s Creek as well as inactivating legacy P in the sediment of the four small lakes within Joe’s Creek flow path. This project proposes an inline automated injection technology for continuous application of a lanthanum-based P sequestration agent into Joe’s Creek, as well as the application of lanthanum-based treatments to sequester sediment-bound P within the four lakes.
