This two-year effort develops innovative 3D-printed materials to remove excess phosphorus from freshwater systems and curb harmful algal blooms. Backed by statewide water-quality investments and prior research, the project will create durable, retrievable structures that provide a more effective, environmentally safe method for long-term nutrient removal. It also includes educational outreach to strengthen the local workforce and public awareness. The work addresses the growing threat HABs pose to ecosystems, public health, the economy and quality of life, driven largely by phosphorus from runoff and other nutrient sources.
