Soil could filter antibiotics from treated wastewater, protecting groundwater

Soil may be a natural filter that can act as a tertiary treatment for wastewater, preventing antibiotics from contaminating groundwater, according to researchers who conducted a study at Penn State's Living Filter.

Researchers analyzed the fate and transport of three  important to —sulfamethoxazole, ofloxacin and trimethoprim—in  and groundwater at the Living Filter, a 50-year-old wastewater reuse system that spray-irrigates treated effluent from the University Park campus' sewage treatment plant on 600 acres of farm and forest. In general, researchers found that each antibiotic behaved differently when exposed to the , but they gained insight into how soil might enhance wastewater treatment.
