Based on a 10% increase in precipitation,  estimated an increased mobilisation of organic carbon from soils to freshwaters of at least 30%, demonstrating the importance of climate wetting for the carbon cycle. Browning negatively affects the taste of drinking water and this may be difficult to address . It also often reduces attractiveness for recreational purposes, especially swimming . Based on a worst-case climate scenario until 2030,  projected an increase in the browning of lakes and rivers in boreal Sweden by a factor of 1.3. The chemical character of DOM, as modified by climate change , determines its amenability to removal by water treatment . Therefore, in order to provide safe and acceptable drinking water, more advanced, more expensive and more energy/ resource-intensive technical solutions may be required .
