Irrigation with reclaimed wastewater and soil amendment with biosolids are increasingly common practices in agricultural systems and result in exposure of crop plants toa variety of wastewater-derived contaminants including pharmaceuticals and personal care product ingredients.Crop plants may take up and accumulate wastewater derived contaminants, but plant-driven processes that influence accumulation are not well understood. We will discuss recent work on how plant modulation of rhizosphere pH can impact the accumulation of ionizable organic contaminants. Results highlighting the influence of other plant-driven processes (e.g., effect of rhizosphere exudates on bioavailability, <i>in planta</i>metabolism of contaminants) will also be discussed.<br/>
