  • How can my laboratory be accredited?
    It depends on whether the laboratory is in New Hampshire or out-of-state. Refer to part Env-C 302 of Env-C 300 Laboratory Accreditation. For a laboratory to become initially accredited, it must first submit a NH ELAP application package along with the appropriate fees. If the laboratory has NH ELAP as its primary accrediting authority, the laboratory will undergo an on-site audit of its facility, personnel, equipment, methods, sample collection, handling, and preservation procedures, quality system, instrument calibration procedures, records and data reporting procedures, use of outside support services and supplies, and handling of complaint procedures for compliance with the NELAC standards. Once the on-site assessment is completed and the laboratory has demonstrated compliance with applicable rules and regulations, it will be granted accreditation. A laboratory that has NH ELAP as its primary accrediting authority must apply for renewal annually. On on-site assessment shall be conducted every 2 years. If the laboratory has NH ELAP as its secondary accrediting authority, only the application with all requested documents and fees are required. The laboratory will be granted accreditation by reciprocity for the fields of testing offered by NH ELAP.

  • Can I use an accredited method for compliance work?
    No, not necessarily. Not all methods NH ELAP accredits for are EPA Approved Methods. Consult with the appropriate department or bureau personnel concerning the work to perform and any analytical requirements they may have. "When the use of reference test methods for a sample analysis are mandated or requested, only those methods shall be used" (NELAC 2001 Standards, 5.10.2.a).
