The University of Waterloo-Environmental Isotope Laboratory (UW-EIL), a research group within the Department of Earth and Environmental Sciences, develops and applies isotope technology to the Environment.

Founded in 1971 by Dr. Peter Fritz, the UW-EIL offers analysis for the isotopes of a number of elements including hydrogen (δ2H, 3H), carbon (δ13C, 14C), nitrogen (δ15N), oxygen (δ18O), sulphur (δ34S), chlorine (δ37Cl), bromine (δ81Br) and strontium (87Sr/86Sr) for a wide variety of applications. UW-EIL is today an innovative modern research facility with an international client base encompassing universities, government agencies, consulting firms and other institutions.
