Nitrogen Leaching from Saybrook Soil Amended with Biosolid and Polyacrylamide

Atrazine leaching from biochar-amended soils.

The herbicide atrazine is used extensively throughout the United States, and is a widespread groundwater and surface water contaminant. Biochar has been shown to strongly sorb organic compounds and could be used to reduce atrazine leaching. We used lab and field experiments to determine biochar impacts on atrazine leaching under increasingly heterogeneous soil conditions. Application of pine ch...

Bioaccumulation of pharmaceuticals and other anthropogenic waste indicators in earthworms from agricultural soil amended with biosolid or swine manure.

Analysis of earthworms offers potential for assessing the transfer of organic anthropogenic waste indicators (AWIs) derived from land-applied biosolid or manure to biota. Earthworms and soil samples were collected from three Midwest agricultural fields to measure the presence and potential for transfer of 77 AWIs from land-applied biosolids and livestock manure to earthworms. The sites consiste...

Emission and Leaching Potential of Mercury from Flue Gas Desulfurization (FGD) Byproducts Amended Soil

The release of mercury (Hg) into atmosphere, infiltration, and uptake by plants from flue gas desulfurization (FGD) material-amended soils was studied. The project was carried out in three phases: (1) laboratory study, (2) field study, and (3) life cycle calculation. In the laboratory study, factors controlling the release of Hg from FGD by-product amended soil were investigated under well-cont...

The use of Biosolid-derived Biochar to Control the Leaching of Nutrients and Bacteria from Agricultural Soil

Field study of methidathion in soil amended with biosolid and a cationic surfactant under different irrigation regimes. Solute transport modeling.

Four experimental plots located in Granada (Spain) were used to investigate the potential movement of the insecticide methidathion during three treatments in a period of three years. To increase pesticide soil retention a municipal biosolid and the cationic surfactant, tetradecyl trimethyl ammonium bromide (TDTMA), were used as soil amendments. The presence of the insecticide was monitored in s...
