Description

Alberta has developed an acid deposition management framework to manage acidifying emissions and resulting acid deposition levels and effects. The framework requires an evaluation of provincial acidifying emissions and resulting acid deposition levels and effects. This report presents the results of the 2011 assessment and reflects the current state of knowledge on provincial acidifying emissions and interpretations of resulting acid deposition levels and effects in the province.

Description

Long term soil acidification monitoring was initiated by Alberta Environment in 1981 to track potential effects of acidic atmospheric deposition on soils in Alberta. Two sites per year were established for a total of eight sites, with baseline sampling completed in 1984. The sites were established each fall at eight locations in the province, as follows: Fort McMurray, Cold Lake, High Prairie, Bruderheim, Devon, Rocky Mountain House, Esther and Twin Butte. In 2008, a ninth site was added in the Fort Saskatchewan Industrial Heartland area in order to provide a better assessment of acidification impacts from major industrial development and oil sands bitumen upgraders proposed for a region. This report presents the data and statistical analysis of six or seven monitoring events up to 2010.

Description

The Alberta Acid Deposition Management Framework stipulates that Alberta Environment is responsible for conducting an evaluation of the acid deposition monitoring data in the province, as well as conducting an evaluation of receptor sensitivity. The present study addresses the latter of these two requirements with respect to potentially acid sensitive soils in the Edmonton East Half map sheet. The objective of this receptor sensitivity study is to provide an estimate of the critical load for the soil types and water bodies in the Edmonton West study area. On the basis of these critical loads estimates, a recommendation regarding the sensitivity of the study area as a whole is provided.

Description

Currently there is no standard method for field measurement and estimation of dry deposition of acidifying pollutants in Alberta. Alberta Environment is pursuing development of an inexpensive standard method. This may involve a combination of continuous, intermittent, and/or passive field measurements of acidifying pollutants and using inference methods for estimating sulphur and nitrogen species dry deposition. An overall objective of this study was to continue evaluating inferential methods for estimating dry deposition rates.
