Predictive Models multiple factors, provides answers now, potential for regional model (unmonitored areas) Need sufficient monitoring data (4-5 days/wk) Improve access to data (NOAA, etc) Need equipment (e.g., monitoring buoys) Need training and technical support Highest Priority Issues for Beach Monitoring in Great Lakes
Affordable Rapid Tests reduce delay, potential for source tracking Need to invest in technology Develop new technology Modify existing technology Highest Priority Issues for Beach Monitoring in Great Lakes
