Acid deposition results when acid forming pollutants are deposited on the earth’s surface. Sulphur dioxide and oxides of nitrogen are the main acid forming pollutants. Deposition of acidifying substances and their reactive products to terrestrial or aquatic ecosystems may result in acidification and damage to the ecosystem.
Management of acidic deposition requires an integrated approach that includes measurement; estimation of emissions and deposition; and evaluation of the effects of deposition on recipient ecosystems.
In Alberta, a management framework has been developed and is based on 4 levels of acid deposition. Each of the levels of deposition corresponds with specific management practices.
For more information on this management framework, see:
Acid deposition assessment
Under Alberta’s Acid Deposition Management Framework, 2 provincewide acid deposition assessments have been completed.

Acid deposition mailing list
The department has an automatic emailing system that will distribute acid deposition related information to those who subscribe to the list. Subscription to this list is open to all department staff, industry, NGOs and consultants, as well as members of the general public.
The personal information collected through the Alberta Acid Deposition Management Framework Acid disposition web page may be used for the purpose of providing you with an Acid Deposition Mailing List subscription to receive provincial acid updates.
This personal information collection is authorized under Section 8 (1) (2) of the Government Organization Act, and is being managed in accordance with Section 33 (c) of the Alberta Freedom of Information and Protection of Privacy Act.
