Management reduces E. coli in irrigated pasture runoff: Microbial pollutants, some of which can cause illnesses in humans, chronically contaminate many California water bodies. This study examined the potential to reduce E. coli contamination from cattle in irrigated pastures. During the 14 irrigation events examined, E. coli concentrations were lowest with a combination of three treatments: filtering runoff through a natural wetland, reducing runoff rates, and letting the pasture rest from grazing at least a week prior to irrigation.
