Research effort has been undertaken to address the problems associated with using REW, both for farmers, but also in terms of health and environmental costs. One such success story has been the use of soil aquifer treatment to ensure greater purification of REW. For Israel to move toward more sustainable use of REW, however, will further require: examining the stringency of treatment standards, investing in treatment infrastructure, and developing research, especially on the concerns related to the possible links between use of REW in agriculture and endocrine disruption in the male population.
