Certified SDWP and VELAP Laboratory Listing (Updated 12/15/2016)
The Division of Consolidated Laboratory Services (DCLS) grants certification of public and private drinking water microbiology and chemistry laboratories in the Commonwealth of Virginia. Laboratories are inspected by DCLS to ensure compliance with quality control practices under Federal and Virginia Safe Drinking Water Program (SDWP) regulations. These regulations include the U.S. Environmental Protection Agency (EPA) Manual for the Certification of Laboratories Analyzing Drinking Water (EPA 815-R-05-004) and Chapter 41, Section 10 through 500 of the Code of Virginia. DCLS also inspects tuning fork laboratories in the Commonwealth of Virginia through carefully planned inspections to ensure compliance with quality control practices under regulations and criteria for laboratories performing calibration of tuning forks under Sections 46.2-882, 19.2-187, and 2.2-1112 of the Code of Virginia. The certification inspections are conducted by DCLS Laboratory Certification Officers (COs).
DCLS also certifies out-of-state laboratories participating in the state reciprocal agreement program under the Commonwealth of Virginia Safe Drinking Water Act (SDWA). Each out-of-state laboratory requesting reciprocal certification under the Safe Drinking Water program in the Commonwealth of Virginia is evaluated on an individual basis. Each laboratory must demonstrate a need to serve customers in Virginia. Laboratories must also be currently certified by EPA or the EPA approved certifying authority of that state. DCLS requirements for initial certification of reciprocal laboratories are outlined in 1VAC30-41-90, Reciprocity.
The Regulation for the Certification of Laboratories Analyzing Drinking Water (1VAC30-41), the protocol for tuning fork laboratory certification and the requirements for initial reciprocal drinking water laboratory certification are provided for your use.
