Microcystin

Application materials are available for laboratories to apply for ELAP certification for Total Microcystins.  Certification for Total Microcystins will be offered in the Drinking Water and Non-Potable Water categories using Total Microcystins by Environmental Protection Agency (EPA) Method 546 – Determination of Total Microcystins and Nodularins in Drinking Water and Ambient Water by Adda Enzyme-Linked Immunosorbent Assay (ELISA) (ELAP method number 9168).

Any laboratories currently performing Total Microcystin analysis using ELISA on Drinking Water and Non-Potable Water samples originating from New York State will need to submit  either or both a primary application in the Potable (Drinking) and Non-Potable Water category and supporting documentation (see below) by Friday, May 4, 2018.  Any laboratory that is currently performing total Microcystin testing and that has submitted a timely application for certification, will be granted interim approval until the application is fully processed by ELAP.  A laboratory will be required to have an on-site assessment performed prior to full certification being granted.

Form 108 - Potable Water - Primary

Form 109 - Non-Potable Water - Primary
