 IQAASL was a project sponsored by the Swiss Federal Office for the Environment to quantify shoreline trash along swiss lakes and rivers. Multiple small scale litter surveys are completed at different locations within a designated survey area. For the year 2020/2021 the survey areas were defined by the municipalities that border the Aare, Rhône, Ticino and Linth/Limmat rivers and any lakes or rivers that are within the catchment area.
