EMSL Analytical, Inc. provides laboratory services on several large Erionite projects. Erionite is listed as a class I carcinogen by the IARC. Work over the past two years has focused on reliable analysis electron microscopy analysis of soil, rock and air samples. EMSL has assisted with method development and is the first commercial lab to offer Cryogenic TEM for defensible Erionite identifications. Two notable projects for Erionite that EMSL has worked on are: characterization of the EPA Erionite reference material used for health studies and providing analysis on a state wide survey of pit material used on NV DOT projects.
