On July 1, 1999, the New Hampshire Environmental Laboratory Accreditation Program (NH ELAP) was formally recognized as a National Environmental Laboratory Accreditation Program (NELAP) accrediting authority. NH ELAP has the authority to require that all laboratories which it accredits to be in compliance with the NELAC standards. To be accredited, a laboratory must have a quality system in place that results in the generation of data of a known and documented quality.
The New Hampshire Environmental Laboratory Accreditation Program provides accreditation to environmental laboratories in New Hampshire, as well as out of state, to ensure sufficiently accurate, precise, and consistent results of tests, analyses, and measurements.
New Hampshire Environmental Laboratory Accreditation Program, NH ELAP, is currently accrediting environmental laboratories according to the July 2003 edition of the National Environmental Laboratory Accreditation Conference (NELAC) Standards.
NH ELAP conducts On-Site Assessments of the laboratories, which are granted primary accreditation. Accreditation is based upon the results of the assessment and the results of the laboratory's participation in proficiency test studies.
Laboratories granted secondary accreditation by NH ELAP are assessed by other NELAP recognized accrediting authorities using the NELAC Standards. Secondary Accreditation is based upon the accreditation granted by the Primary Accrediting Authority.
NH ELAP offers primary and secondary accreditation for Potable Water (drinking water), Non-Potable Water, (wastewater and whole effluent toxicity testing), Non-Potable Water SW-846 and Solid and Chemical Materials SW-846 methods.
