b'21A novel effective, fast and frequent monitoring system forphosphate within a catchment OGrady J1, deEyto E2, Jennings E3, McGinnity P4 and Regan F11DCU Water Institute, Dublin City University, Dublin, Ireland2Marine Institute, Furnace, Newport, Co. Mayo, Ireland3School of Biological, Earth and Environmental Sciences, University College Cork, Cork, Ireland4Centre for Freshwater Studies and Department of Applied Sciences, Dundalk Institute of Technology, Dundalk, IrelandCatchment monitoring with an emphasis on water quality is a growing area of critical importance within recent years. [1] Catchments can be extremely complex systems where the quality and quantity of the water is influenced by biological, chemical and physical factors. [2] A catchment area for water is usually defined as the area of land around a lake, river or some form of water body. [3] Catchment monitoring is important as it provides a strong approach to sustainable management of the area, it can also highlight problems or threats concerned with the area.Monitoring systems are put in place to better understand the key drivers influencing the quality of the water bodies and land surrounding the catchment. The Burrishoole catchment in Newport, Co. Mayo is the focus of this study. Burrishoole is a highly instrumented and monitored catchment. Long-term data sets are widely available that date back to the 1950s. These datasets contain information on water temperature, precipitation pH, and dissolved oxygen. This work aims to demonstrate the need for novel multi-test phosphate sensor that is capable of on-site frequent analysis of phosphate levels in real time throughout the many lakes and rivers within a catchment area.
