Flow-Proportional passive sensor validation of phosphorus and nitrogen in Irish rivers (Flow-Pro)
Flow-Pro will test a new passive, flow-proportional sampling solution for phosphorus and nitrogen in rivers. The passive system is based on cartridges that are exposed in flowing water over defined time periods and absorb nutrients, proportional to the velocity of influent water, which are subsequently extracted in the laboratory. Over a 12 month period, weekly, fortnightly and monthly exposure periods and subsequent extractions will be compared with high resolution datasets of phosphorus (TP and TRP) and nitrate (NO3-) in a flashy Irish river catchment. These data will be collected from existing flow and P infrastructure, augmented with new N infrastructure. The Flow-Pro project will deliver: The most complete validation of P and N passive water quality sensors by comparing exposures to unsurpassed continuous P and N concentration data coverage from established and augmented stations. A report and technical workshop for the EPA and provide recommendations for using this technology in routine water quality monitoring and also for ongoing/future research into nutrient transfers from land to water. At least two peer-reviewed publications submitted to Environmental Science and Technology, the foremost journal in the environmental sciences and a regular outlet for emerging scientific technologies.
