Introduction Inception of Program Activities What We Have Learned Statewide Coordination Reporting to the Public IDEM Monitoring Activities in Upper Fall Creek Watershed Future IDEM activities
Inception of Programs Public concerns about algae blooms in Geist Reservoir in 2007 Dr. Tedesco/CEES work in reservoirs Senator Gard’s call for coordinated approach to examining this issue
What We Have Learned Traditional assumptions of when algae blooms occur have been challenged. Nutrient loadings from a variety of sources, including residential, agricultural, point sources contribute to the problem. Existence of cell counts does not necessarily imply high toxin levels. High toxin levels can occur with low cell counts.
Statewide Coordination IDEM has partnered with DNR, ISDH, Indianapolis/Veolia Water, and IUPUI’s Center for the Earth and Environmental Sciences (CEES) to monitor local reservoirs. IDEM/ISDH partner on Blue Green Algae level advisories to provide public with information.
World Health Organization Thresholds Reporting To the Public:
