Environmental Site Assessment Repository (ESAR)

The Environmental Site Assessment Repository is an online, searchable database that provides scientific and technical information about assessed and/or reclaimed 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.

Reclamation certificates issued for upstream oil and gas well sites, gravel pits and other specified lands on private land and the associated file information for the certificates (applications, reports) are also available on ESAR.  Reclamation certificates issued for sites on public lands of the province) are available through Sustainable Resource Development (CrownLandDataSupport@gov.ab.ca)

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,  Tips and Tricks document 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.
