In line with the current World Health Organization (WHO) guidelines for the safe use of wastewater, excreta and grey water in agriculture, IWMI is exploring low-cost options which can be implemented all the way along the food chain, from farms to markets to consumers. To make appropriate recommendations, scientists assess risks by sampling the locally available water and irrigated crops. Then they identify the most effective ways to remove pathogens by making changes in common practices.
