Sampling Procedures. Under the IM 15 monitoring program, water samples will be collected early in the bloom season (spring and early summer) for phytoplankton species cell identification/enumeration to determine the presence and abundance of cyanobacterial species (e.g., Dolichospermum sp., Aphanizomenon sp., Microcystis sp., etc.). Sampling entities will specify a 48-hour rush turnaround on analysis of all of these phytoplankton samples. Water samples will also be collected for cyanotoxin analysis by one of two methods: ELISA for total microcystins, analyzed by the EPA Region 9 lab, in accordance with the U.S. EPA Region 9 Laboratory Standard Operating Procedure (SOP 1305 for Microcystin analysis by ▇▇▇▇▇). Liquid Chromatography - tandem Mass Spectrometry (LC/MS/MS) for microcystin congeners and anatoxin-a analysis (per Mekebri et. al., 2009). Sample collection and preservation will be conducted in accordance with the Cyanobacteria SOP (KBGAWG 2009).
