Title: An assessment of mercury contamination in the Red River catchment : final draft report
Author: Tim Geatches
Document Type: Monograph
Abstract:
In 1990 a report to the Regional Advisory Board identified a risk of failure for total mercury with the EC dangerous substance directive in the Red River. The report recommended an immediate investigation to determine the source of mercury and eliminate contamination. In 1992 a report of the investigation identified the discharge from South Crofty Mine to be the probable source of mercury. The storage or milling of imported ore within South Crofty mine was thought to have been the source. However, mercury was also thought to be present in the natural geology. A follow up investigation in 1993 of South Crofty mine concluded the ultimate source of mercury was from the natural geology. The report recommended further analysis to determine whether the mercury is of mineral or elemental origin.
