Timothy McGrath, a sixth-year student from Community College Killorglin, was named the overall winner of SciFest 2019 for his research and development of a biofilter to combat oceanic and freshwater dead zones. Timothy will go on to represent Ireland at the International Science and Engineering Fair (ISEF) in Anaheim, California next May.

The SciFest 2019 National Final took place in the Marino Conference Centre in Dublin on 22 November. The fair was officially opened by Richard Bruton TD, Minister for Communication, Climate Action and Environment . Timothy was presented with the SciFest 2019 SFI ISEF Award by Margie McCarthy, Head of Education and Public Engagement, Science Foundation Ireland. Timothy secured his place at the National Final after his victory at the SciFest regional final in IT Tralee.

Through research Timothy realised that eutrophication, an enrichment of water by nutrient salts, which causes structural changes to the ecosystem, turns huge areas of the ocean into dead zones and affects many countries as a result. Dead zones are low-oxygen areas in the world's oceans and large lakes, caused by excessive nutrient pollution from human activities. Timothy created a technically viable solution and built a structure that stored a halophyte ecosystem that would reduce nutrient pollution, decreasing algal blooms and deoxygenation of ocean water and freshwater.

Timothy was one of 77 students who qualified to exhibit 41 STEM projects at the National Final.
