This project investigated the fate and transport of pharmaceuticals and personal care products (PPCPs) in turfgrass/soil systems irrigated with recycled water. The project involved laboratory adsorption and degradation experiments, controlled lysimeter experiments, field-scale controlled plot monitoring of drainage concentrations, and mass flux below fairways on four different golf courses. Fourteen different compounds were monitored in the irrigation and drainage waters.
The results support the use of recycled water for irrigation purposes, as long as sound, science-based irrigation management practices (e.g., cycle and soak irrigation) are implemented. The use of recycled water allows communities to extend their water resources while minimizing the discharge of such waters into aquatic systems.
