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.

The University of Waterloo plans to have necessary labs back in operation by mid-July with the most critical facilities starting the soonest, with limitations on the number of people permitted in each facility. The Environmental Isotope Lab is expected to be in Phase 1 and is in the process of applying as a critical need facility. More information will 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.
