HS04 Methodologies for risk assessment of waste water re-use
on groundwater quality
Re-use of waste waters is one method for conserving regional water resources. However (pre)treated waste waters contain elements and compounds that may damage environmental quality. Poor management of waste water treatment facilities can also harm the environment. Pre-treated waste water can also be used for irrigation of agricultural crops. But what pre-treatment is necessary and at what rate can the treated waste water be applied to soils without soil degradation occurring? What are the relevant physical, chemical and biochemical processes in the top-soil after application and during its transport to greater depth?
