Water is needed both in production and processing of leafy greens and as such may serve as a source of enteric pathogens.  Depending on the source of the water, variations in quality and safety occur.  Unfortunately, increasing demands as well as pollution of existing resources have led to increasingly scarce high quality freshwater resources.  Consequently, water reuse for both food production and food processing will likely increase in the future.
