Welcome to the Environmental Isotope Laboratory


PLEASE BE AWARE. Due to the ongoing COVID-19 outbreak the University of Waterloo Environmental Isotope Lab has temporarily suspended operations in compliance with University of Waterloo policy and Ontario provincial emergency orders. Please refrain from shipping samples (especially perishables) in the interim due to the possibility of service interruptions associated with couriers and shipping.

As the University of Waterloo begins the process of strategically reopening the UW-EIL will be prioritised as a part of Phase 1 with more information to be provided when available. In the meantime please refer to the University of Waterloo Coronavirus update page for the most up-to-date information on the status of the University of Waterloo campus.

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.
