Do contaminants rebound?

Contaminant concentrations may increase (typically 1-2 months) after application as a result of desorption by biological surfactants associated with the biodegradation process. Desorption of contaminants adhered to soil particles in both the saturated and unsaturated zone can contribute to an increase in groundwater contaminant concentrations, especially if free product is present. The concentrations will subsequently decrease over time.
