Four WRRC students took top spots in two student poster contests at this year’s Pacific Water Conference (PWC) in Waikiki.
It was a WRRC clean sweep in the Hawaii Water Environment Association (HWEA) student poster contest, with Brian Allen placing first ($250), Erik Hoffnagle second ($200), and Junxi Dai third ($150).
Brian’s winning poster was titled, “Understanding and Mitigating Hexavalent Chromium Risks in Maui Wildfire-Impacted Agricultural and Forest Soils.”
Erik’s poster was titled, “Preliminary Testing of a Floating TDS Sensor for Inflow and Infiltration to Sanitary Sewers.”
Junxi’s poster was titled, “Carbon Source-driven Enrichment of Phosphate Accumulating Organisms in EBPR Systems.”
Engineering MS student Claire Pedersen won second place in the American Water Works Association (AWWA) poster contest, taking home $240. Her winning poster was titled, “Comparing Water Treatment Solutions in American Samoa: An Engineering Feasibility Assessment of Reverse Osmosis and Microfiltration.”
Congratulations, Brian, Claire, Erik, and Junxi! You make all of us at WRRC very proud!
