Description

These three reports present the results of a sampling and delineation program conducted as a part of the Environment and Parks investigation of the former Domtar Edmonton Wood Treatment Facility. The sampling and delineation program was conducted by an independent third party consultant. Some samples from this testing show the presence of chemicals known to be harmful to people in large amounts or over long periods of time.

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...
