1) Collect representative soils from DDx and dieldrin contaminated areas of the North Farm at BARC; 2) Identify earthworm species which occur in these soils; 3) Test the effect of organic matter amendments (manure compost; biosolids compost; biochar) on bioaccumulation of DDx by common soil earthworms; 4) Test the effect of growing crops in the earthworm bioaccumulation assay soil on the bioaccumulation of DDx and dieldrin by earthworms; 5) Examine the effect of treatments on nutrient and trace element accumulation by the earthworms; 6) Examine the effect of the soil amendments on changes in soil microflora which may affect earthworm activities; and 7) DDx and dieldrin and other halogenated hydrocarbon analyses to be provided by cooperators.
