Environmental Site Assessment Repository (ESAR)

The Environmental Site Assessment Repository is an online, searchable database that provides scientific and technical information about assessed sites throughout Alberta.

Environmental site assessments determine the quality of soil and groundwater of a site, particularly at retail gas stations and other commercial and industrial sites. A site assessment does not necessarily mean a site is, or ever was, contaminated.

Using Alberta Registries Land Titles SPIN2 technology, the Environmental Site Assessment Repository allows you to search for a site by legal land description, municipal address or map. If information on a site is available, users can download, email and print relevant information and documents.

Please review our Frequently Asked Questions or the User Guide if you are having any trouble accessing information on the Environmental Site Assessment Repository. If you do not find the information you require, please contact ESAR-Support@gov.ab.ca.
