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?
