  2. Algal Assessment Program Review • Water Sciences Section, Ecosystems Branch • Coordinate with: • Regional Offices • Public Health Dept. • Academic Institutions • Sea Grant • Fish and Wildlife • Wildlife Resources Commission • Private Citizens and more

  3. Potential Harmful Algal Blooms (pHABs) • DWR defines pHABS as: • Blooms of bluegreen algae that may produce toxins • Densities above 10,000 units/ml • PUBLIC HEALTH RISK = PUBLIC HEALTH DEPT. • Algal bloom investigations • Regional Offices • Estuarine Monitoring Team • Episodic (1 to 7 days) • 50 in 2017 • 20 considered pHABs • XX so far 2018 • XX considered pHABs • Chronic (1 to 3 months, returning annually) • Fontana Lake > 2015 • Chowan River/Albemarle Sound > 2015

  4. Cyanotoxin Testing Development • Field Staff/Regional Office • Abraxis cyanotoxin test strips • Rapid assessment • Field or office use • Limited results (no verification procedures) • Water Sciences Section Chemistry Laboratory • Abraxis Cyanotoxin Automated Assay System • ELIZA instrument • Quality assurance and Quality Control procedures • sample collection, handling & processing procedures

  5. Current Focus and Efforts • Draft pHAB and Cyanotoxins Sampling Protocols out for review • Staff and Interagency • Cape Fear River Partnership • Basinwide Lake Monitoring Program • Testing for Microcystin in Water Supplies • Special Studies • Split samples with DPH • Test strips vs ELIZA • National Rivers and Stream Assessment • Waterville • White Lake

  6. Fish Kill and Bloom Reporting APP • Developed as a Fish Kill reporting tool • Reconfigured to include reporting algal blooms • Downloaded to phone or via the web • 60 fish kills where reported with this app in 2017 • 10 algal blooms were reported since spring 2017
