With a growing population, exploitation of natural resources increases and the need for cost efficient measures to reduce environmental impact is vital. This includes corporate environmental responsibility which could be reached through the use of ecosystem services. Constructed wetlands (CWs), can be used for treatment of drainage water and minimize harmful impact of dissolved and particulate substances from quarries. In the past, degradation of wetland habitats have resulted in loss of important ecosystem services. By CWs, we can rehabilitate both biodiversity and retention functions in a watershed. The quarry in Degerhamn, southeast Sweden, is located in a unique, semiarid alvar landscape. Typically, streams and wetlands of the alvar are small and ephemeral. Shortage of water is a main structuring factor for the ecological communities. The quality and availability of water is also of primary importance for the agricultural society. In order to compensate for the sink of groundwater into the quarry, water is pumped up the alvar and allowed to flow downstream in the catchment area. Through carefully designed monitoring, water sampling and analysis of nutrients, we will estimate nutrient loading from the quarry. Bioassays will be used to analyze limiting nutrients. Based on this information, we will propose a design of treatment wetlands. The purpose of the project is to show how wetlands functions can be optimized to local conditions in a quarry.
