Recycled Sewage Water Is Safe for Crop Irrigation, Study Suggests

Sep. 9, 2013 — The first study under realistic field conditions has found reassuringly low levels of pharmaceuticals and personal care products (PPCPs) in crops irrigated with recycled sewage water, scientists reported in Indianapolis today at the 246th National Meeting & Exposition of the American Chemical Society (ACS).

“The levels of pharmaceuticals and personal care products that we found in food crops growing under real-world conditions were quite low and most likely do not pose any health concern,” said Jay Gan, Ph.D., who led the study. “I think this is good news. These substances do not tend to accumulate in vegetables, including tomatoes and lettuce that people often eat raw. We can use that information to promote the use of this treated wastewater for irrigation.”
