Mission Statement

ESAL is the only university soils laboratory in Nevada providing routine analyses of geologic materials, soils, plants, and water to the general public. ESAL’s mission is to maximize efficiency of laboratory resources by providing accurate, reliable, and prompt services to the research programs within UNLV, and to external public and private entities in Nevada and the region, at reasonable costs.

At ESAL, all samples are analyzed according to the United States Environmental Protection Agency (EPA), Department of Agriculture Natural Resources Conservation Service Soil Survey Laboratory Methods Manual (Soil Survey Staff, 2004) and Soil Science Society of America or regional authorities (reference sources vary with individual items). Analyses of geologic materials vary with user needs. All analyses are performed under rigid routine quality control procedures.

Our Laboratory

The Environmental Soil Analysis Core Laboratory (ESAL) is part of the Department of Geoscience, University of Nevada Las Vegas (UNLV). It is located in the new Science and Engineering Building (SEB), rooms 4118 to 4120. ESAL is capable of providing routine analyses of geologic materials, soils, plants, and water, including chemical, physical and mineralogical analysis of soils or other geological materials, and chemical analyses of plant and water samples. Our most significant expansion in analysis capacity recently is duo to the addition the Agilent 7700x ICP-MS and Labconco Filtered Balanced System, which enabled us to analyze almost every element. We can also deal with soil or rock samples containing asbestos.
