Contamination of soils and sediments in the vicinity of a mercury recovery plant

River water, sediment, and soil samples were analyzed to determine the contribution of an adjacent mercury recovery plant to local Hg contamination. Soil samples from sites subjected to runoff and located near the plant's landfill, contained Hg levels in excess of 10 ppm. A sediment sample from...

Description
Summary:River water, sediment, and soil samples were analyzed to determine the contribution of an adjacent mercury recovery plant to local Hg contamination. Soil samples from sites subjected to runoff and located near the plant's landfill, contained Hg levels in excess of 10 ppm. A sediment sample from a dry river bed contained 49.6 ppm Hg. Identification of the recovery plant as a point source is consistent with the progressive reduction in Hg levels as the distance increases from the dry river bed site to the permanent source of the river.
