New Cecil Day Family Center for International Groundwater Innovation Announced by Mercer University

G³⁶⁰ collaborator,  Mercer University,  recently announced the establishment of the Cecil Day Family Center for International Groundwater Innovation. The new center, led by Dr. Michael MacCarthy, will accelerate efforts in the Mercer On Mission program and the School of Engineering to provide access to clean water to the world’s most water-poor communities. The Center will focus on three core components – household self-supply, small community water systems and global groundwater innovation. The G³⁶⁰ group is excited to move into a new phase of collaborative research with Dr. MacCarthy and his group and congratulate them on this exciting news!

Dr. Jana Levison Receives the IAH-CNC Early Career Hydrogeologist Award

University of Guelph Associate Professor and G360 Principal Investigator, Dr. Jana Levison, was awarded the IAH-CNC Early Career Hydrogeologist Award announced this week in recognition of her leadership and engagement in the hydrogeological community. Dr. Levison is an active researcher in the areas of agricultural impacts on groundwater quality and quantity, impacts of climate change on hydrological systems, groundwater flow and contaminant transport in fractured geologic media, and source water protection for Indigenous and rural communities. Jana has taught numerous undergraduate and graduate students about hydrogeology and has supervised over 20 students as either primary or co-advisor, to date. In the hydrogeological community, Jana has served on major conference technical committees and as an Associate Editor of the International Association of Hydrogeologists’ Hydrogeology Journal and reviewer for water related grant applications. Jana’s impact on research and contributions to the field of hydrogeology are impressive and she has established research domains with new colleagues in a collegial and highly collaborative manner. Congratulations Jana on this distinguished early career award!

Ground Water Canada Features Upcoming Plans for the G³⁶⁰ BAFF

Dr. Beth Parker was recently featured in Ground Water Canada Magazine after being interviewed on her vision for the on-campus Bedrock Aquifer Field Facility (BAFF). Funding was approved earlier this year, and the new, research-focused, educational facility will highlight groundwater and serve as a hub for the public and professionals alike.

CEPS Highlights G³⁶⁰ Groundwater Remediation Research

The College of Engineering and Physical Sciences (CEPS) at the University of Guelph recently featured G³⁶⁰ groundwater remediation research headed by Dr. Beth Parker, including team members Dr. Kari Dunfield and Dr. Philip Wanner. The article highlights how new multi-disciplinary methods provide seasonal data that can help protect groundwater using monitored natural attenuation (MNA). With MNA, a range of physical, chemical and biological processes can be used to naturally reduce (attenuate) contaminants, as demonstrated at a historic manufacturing facility in southwestern Ontario.

Abstract:
Optical sensors are promising for collecting high resolution in-well groundwater nitrate monitoring data. Traditional well purging methods are labor intensive, can disturb ambient conditions and yield an unknown blend of groundwater in the samples collected, and obtain samples at a limited temporal resolution (i.e., monthly or seasonally). This study evaluated the Submersible Ultraviolet Nitrate Analyzer (SUNA) for in-well nitrate monitoring through new applications in shallow overburden and fractured bedrock environments. Results indicated that SUNA nitrate-N concentration measurements during flow cell testing were strongly correlated (R 2 = 0.99) to purged sample concentrations. Vertical profiling of the water column identified distinct zones having different nitrate-N concentrations in conventional long-screened overburden wells and open bedrock boreholes. Real-time remote monitoring revealed dynamic responses in nitrate-N concentrations following recharge events. The monitoring platform significantly reduced labor requirements for the large amount of data produced. Practitioners should consider using optical sensors for real-time monitoring if nitrate concentrations are expected to change rapidly, or if a site’s physical constraints make traditional sampling programs challenging. This study demonstrates the feasibility of applying the SUNA in shallow overburden and fractured bedrock environments to obtain reliable data, identifies operational challenges encountered, and discusses the range of insights available to groundwater professionals so they will seek to gather high resolution in-well monitoring data wherever possible.
