Overview

The New Hampshire Environmental Laboratory Accreditation Program (NH ELAP) provides primary accreditation to environmental laboratories located in New Hampshire to ensure sufficiently accurate, precise, and consistent results of tests, analyses, and measurements. Primary and secondary accreditation is also granted to out-of-state environmental laboratories. NH ELAP is currently accrediting environmental laboratories according to the July 2003 edition of the National Environmental Laboratory Accreditation Conference (NELAC) Standards. The program's goal is to move to the latest approved version of the TNI Standards once the rules update process has been completed. In general, primary accreditation is based upon the results of the on-site assessment and the results of the laboratory's participation in proficiency test studies. Secondary accreditation is based upon the accreditation granted by the Primary Accrediting Authority. NH ELAP offers accreditation for a variety of 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.
