Description

This document focuses on Tier 1 soil and groundwater remediation guidelines, the process used to develop them, and the manner in which they should be applied. Alberta's framework for the management of contaminated sites is designed to achieve three policy outcomes: pollution prevention, health protection, and productive use. Under this framework, three management options are provided: Tier 1, Tier 2, and Exposure Control. Tier 1 remediation guidelines are generic; that is, they are developed to protect sites at the more sensitive end of the range and can therefore be used at most sites without modification.

Description

Alberta's framework for the management of contaminated sites is designed to achieve three policy outcomes: pollution prevention, health protection, and productive use. Under this framework, three management options are provided: Tier 1, Tier 2, and Exposure Control. Under Tier 2 it may be possible to screen out certain exposure pathways and/or modify the Tier 1 guidelines on the basis of site conditions. This companion document describes how the Tier 2 approach might be used to develop remediation objectives for a site.

Description

Deposition of air-borne sulphur dust from industrial facilities that handle or process solid elemental sulphur has the potential to cause soil acidification at or near those sites in Alberta. Lack of suitable analytical methods for elemental sulphyr has become a challenge for soil monitoring for industry operators and regulators. An acetone extraction-sodium cyanide colorimetric analysis method has been used in Alberta but environmental consultants and laboratories complained about the high detection limit and questioned its reliability. A chloroform extraction-HPLC analysis method developed in New Zealand was reported to work well with a wide range of agricultural mineral soils and some sediments. It was not clear if it would be suitable in Alberta because the impact of elemental sulphur on soils is frequently monitored in forested sites where organic materials from forest litter may interfere. There was also a need to assess if the above-noted methods were compatible with the...
