DAEMONS kicked off in early 2020, with the first field samples collected in the Anråse river catchment in January. Shortly afterwards the COVID-19 pandemic began, putting a temporary stop to sampling. Despite this, the first stakeholder meeting went ahead as planned on the 15th April, albeit in the virtual, rather than physical world. Present for the meeting were a small but diverse range of stakeholders, with representatives from:
Representing the DAEMONS project team were Filip Moldan, Sara Jutterström and Johanna Stadmark (IVL), Martyn Futter (SLU), and Sofia Hjalmarsson and Lars Johansson (DHI). The team gave an overview of the project, including the aims, scientific background and model simulations of the dispersion of solutes from the river mouth into the fjord system, before the preliminary data were presented from the January, February and March sampling campaigns. The monthly sampling sites cover a range of the main land uses (identified as key end members) present in the Anråse river catchment: agricultural streams, forest streams, mire streams, lakes and river outlets. Total phosphorus concentrations in January for the different lake and stream sampling sites. The two sites with the highest concentrations (LE1.5 and LE2) are agricultural streams. The stakeholder group provided feedback on the early results with particular discussion about high phosphorus levels in some streams: is this diffuse emission from agriculture, or coming from point sources such as septic tanks? A question to investigate in future, and one that could perhaps be answered with extra analyses (e.g. E.coli). There were also requests to include specific lakes in the large-scale synoptic sampling campaigns that are planned quarterly, and to ensure oxygen concentrations were measured. Useful local information was also provided about water treatment works, pumping stations and other relevant people to make contact with. All in all, a very productive first meeting.
