To fill existing data gaps on drainage from lands that have been irrigated with treated wastewater or that have been fertilised directly with animal manure or derived bio-solids (e.g. after digestion or further processing), the European Commission is looking for participants to join the exercise by providing access to suitable test sites and manure samples.Further information and the terms of participation are provided in the links below.

Interested researchers or research facilities are invited to express their interest by 31 August 2018.
