The Protection Against Legionella regulation requires that all Legionella culture analyses be performed by a laboratory approved by the New York State Environmental Laboratory Approval Program (ELAP) to perform such analyses.
Certification for Legionella culture analysis is offered in the category of Non-Potable Water using International Standard Method 11731 Water quality-detection and enumeration of Legionella (ISO 11731). It is also offered for certification in Potable Water using the same method.
Application materials for these categories are provided.
Applicants are required to submit proficiency testing (PT) results for Non-Potable samples only from any TNI and ISO/IEC 17043:2010 accredited providers. Applicants must demonstrate passing scores in at least two (2) of three (3) consecutive proficiency tests performed at least fifteen (15) days apart.
An on-site assessment must be performed prior to certification being granted.
