Water shortages in agriculture could be overcome with novel approaches to irrigation. By re-using treated industrial and domestic wastewater for irrigation, it is possible to reduce agriculturally induced demand on freshwater. However, as wastewater treatment technologies are not perfect, this would introduce contaminants of emerging concern (CECs) into the soil. Sub-surface irrigation can mitigate this problem to some extent, as CECs are degraded, transformed, or immobilized in the soil, such that they do not reach deep groundwater or the root zone. This project revolves around building physical models to characterize the risks and effectiveness of sub-surface irrigation with treated wastewater.
