Abstract

Arkelstorpsviken is a lake in Kristianstad municipality with eutrophication problems known since the 1970s. Several projects have been run over the years in order to identify and address sources of influence. In this thesis, new sampling locations have been selected to be able to identify additional sources of influence. Analysis of phosphorus and nitrogen has been performed to obtain an estimate of the water status in each watercourse. The purpose has been to investigate whether there are specific differences in the nitrogen and phosphorus levels at the sampling locations, identify point sources with a negative impact on water quality and investigate society's impact on nutrient load by locating sampling locations upstream and downstream of the communities Lerjevallen and Oppmanna. Two sources of impact were identified with high levels of phosphorus coming from the Immeln and Arkelstorp wastewater treatment plants. However, the two wastewater treatment plants meet the set requirements and limit values according to the wastewater directive. Studies concerning private sewers and the impact of agriculture have not yielded any definite results. In order to be able to draw reliable conclusions about these sources of influence, sampling opportunities in further studies should be located during, for example, low water flow. Proposed measures to improve outgoing water quality from Immeln's wastewater treatment plant are to construct a wetland as an additional treatment step.
