The Vermont Department of Health certifies laboratories analyzing drinking water as per Vermont Statute 18 V.S.A § 501b. Applicant laboratories need to be accredited by a National Environmental Laboratory Accrediting Program (NELAP) recognized accrediting body to the TNI standards currently in effect before the department will consider issuing a drinking water certification to the laboratory.
A sample is required to be analyzed by a laboratory certified by the Vermont Department of Health when:
The sample is from a public water system and the results are to be submitted to the VT Drinking Water and Groundwater Protection Division (per Section 21-13 of the Vermont Water Supply Rule).
The sample is from (non-public) potable water sources and is being analyzed for the purposes of permitting (per Section 1-1113(c) of the Vermont Wastewater System and Potable Water Supply Rules).
Any laboratory that is certified by the VT Department of Health which analyzes a groundwater drinking water sample (regardless of the reasons for analysis) must submit the results of their groundwater analyses to the Department of Health in a format required by the Department of Health (per 18 V.S.A § 501b).
