Opportunity: Water quality indicators can be monitored with satellites and used to protect public health. Approach: Strengthen cross-agency research to mainstream satellite capabilities for water quality management decisions. Results: New methods and tools to monitor cyanobacteria harmful algal blooms (HABs). Impact: Scalable information across any geo-political boundary, and ability to prioritize locations for management actions. f Sierra Club v. EPA 18cv3472 NDCA Schaeffer et al. 2015. Agencies collaborate, develop a cyanobacteria assessment network. Eos. 96:16-20. Tier 10 ED 002061 00270537-00002 Quantifying Cyanobacteria Frequency Problem: How do we quantify bloom frequency? arw ai*w srw Action: Site-specific frequencies >100,000 cells/mL. Result: Derive relative exposure risk profiles from frequency data. Impact: Ability to prioritize locations for management actions, e.g. surface water intakes or recreational waters. 3 Sierra Club v.

Tier 10 ED 002061 00270537-00003 Quantifying Cyanobacteria Extent Problem: How do we quantify the spatial extent of cyanobacteria? Action: Time series analysis evaluated overall trend. Result: 2008-2012 and 2017+ for the continental U.S. (CONUS). Impact: Each year report on status of HABs in the U.S. by state. Sierra Club v. EPA 18cv3472 NDCA 4 Urquhart et al. 2017.
