Managing Beef Backgrounding Residual Soil Contaminants by Alum and Biochar Amendments.

abstract：:Perchlorate (ClO4-) contamination of ground water and surface water is a widespread problem, particularly in the western United States. This study examined the effect of biodegradation on perchlorate fate and transport in soils. Solute transport experiments were conducted on two surface soils. Pulses of solution conta...
