Options and Recommendations for a Polybromobiphenyl Control Strategy at the Gratiot County, Michigan Landfill
Abstract
The Gratiot Country (Michigan) Landfill received large amounts of waste polybrominated biphenyls (PBBs) in the period 1971 to 1973. With use of the Preliminary Pollutant Limit Value (PPLV) method, provisional limits were calculated for PBB concentration in soil and water in the area surrounding the landfill. Separate PPLV values were calculated for agricultural, residential and industrial land use scenarios. The method begins with an estimate of a maximum allowable daily dose for man. Then for each land use scenario, significant pathways from soil or water to man are identified. For each pathway taken by itself a maximal allowable PPB level (single-pathway PPLV) is calculated. Relevant single-pathway PPLVs are then used to calculate a PPLV value for each land use scenario. Results indicate that the agricultural use scenario is associated with the most stringent soil PPLV (0.18 ppm), due largely to ingestion of soil by cattle. The corresponding value for residential use, 45 ppm, was governed by soil ingestion by children. Least stringent was the PPLV for industrial use, 700 ppm, based on dust inhalation. Potable water for humans was not considered in the above figures, but the (perhaps avoidable) contamination of such water was shown to require corresponding reductions in the soil PPLVs.
