LETL Lab Testing Accreditations
The Loyola Environmental Testing Lab is participating in third-party accreditation to ensure the quality of analytical testing and validation for results used in any research, reports, or application. LETL is currently accredited with the North American Proficiency Testing (NAPT) for soil testing, and is pursuing accreditation from the Illinois Environmental Protection Agency Laboratory Accreditation Program (IEPA-LAP) for water testing.
North American Proficiency Testing Program (NAPT)
Soil Accreditation - May 2017
The North American Proficiency Testing (NAPT) Program (a program of the Soil Science Society of America) assists soil, plant and water testing laboratories in their performance through inter-laboratory sample exchanges and a statistical evaluation of the analytical data.
The program guidelines have been developed for the agricultural laboratory industry by representatives from groups familiar with and involved in standardizing methods and developing nutrient recommendations for soil and plant analysis methods within the U.S. and Canada. It is operated as an activity of the Soil Science Society of America and overseen by an oversight committee comprised of representatives of the above-mentioned groups. These include: Regional Soil and Plant Analysis Workgroups; Scientific Organizations; State/Provincial Departments of Agriculture; and private and public and plant analysis labs.
Illinois Environmental Protection Agency Laboratory Accreditation Program (IEPA-LAP)
Water Accreditation - Application Pending
The Illinois Environmental Protection Agency's Environmental Laboratory Accreditation Program (IL ELAP) operates pursuant to authority in the Illinois Environmental Protection Act, which authorize the Illinois Environmental Protection Agency to "establish and enforce minimum standards for the operation of laboratories relating to analyses and laboratory tests for air pollution, water pollution, noise emissions, contaminant discharges onto land, and sanitary, chemical, and mineral quality of water distributed by a public water supply, and to "issue certificates of competency to persons and laboratories meeting the minimum standards established by the Agency...and to promulgate and enforce regulations relevant to the issuance and use of such certificates."
The IL ELAP offers accreditation for the analysis of various inorganic and organic analytes in the following fields of testing: Drinking Water, Wastewater and Hazardous Waste. Accreditation is based on the field of testing, approved test method and analyte. Participation in the IL ELAP is voluntary except for any laboratory submitting community water supply water compliance data to the Illinois EPA, Bureau of Water, Compliance Assurance Section.
