NC WW/GW Laboratory Certification Program
Note: The Division of Water Quality merged with the Division of Water Resources on August 1, 2013. The NC WW/GW Laboratory Certification Program is now part of the new Division of Water Resources (Water Quality Programs).
The North Carolina Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) program is a vital component in the effort to ensure the quality of analytical data used for regulatory purposes by various programs within the Department of Environment and Natural Resources (DENR). These programs rely on the services of the NC WW/GW LC program to support a multitude of scientific, regulatory and administrative decisions.
The NC WW/GW LC program is a parameter-based, method-driven program. The name refers to North Carolina regulatory programs and is used to differentiate the NC WW/GW Laboratory Certification program from the Drinking Water Certification and Biological Laboratory Certification programs. It is not meant to exclude certification of laboratories analyzing soil, sediment or other matrices. The NC WW/GW LC program operates pursuant to authority contained in North Carolina General Statute 143-215.3(a)(1) and 143-215.3(a)(10). It is a fee-supported program managed by the Division of Water Resources (DWR) Laboratory Section. The rule governing laboratory certification is North Carolina Administrative Code, 15A NCAC 2H .0800, which provides procedures for laboratories applying for certification, establishes laboratory certification fees and provides the appropriate methods and references for evaluating laboratory competence. The purpose of certification is to determine that a laboratory has the necessary technical competence, facilities and equipment to perform the required laboratory analytical procedures. Key elements of this certification include:
The program certifies more than 730 environmental laboratories in North Carolina and throughout the United States under the following categories:
Efforts to improve the quality of monitoring data ranks among the most important functions of the NC WW/GW LC staff. In addition to certification, staff also provide technical support and training to environmental laboratory personnel to assist in improvement of laboratory operations, quality systems and understanding of the framework of regulatory requirements which govern environmental laboratory operations.
Initial Application Procedures
Information regarding initial application to the program can be found at the following links:
Field laboratory certification applies to laboratories, its agents or employees seeking to analyze samples for field parameters only. These parameters include Total Residual Chlorine, Conductivity, Dissolved Oxygen, pH, Settleable Residue and Temperature. Field commercial certification applies to a laboratory, its agents or employees seeking to analyze field parameters for others for a fee.
