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.

A Fellow Speaks: Beth Parker Featured in AGU Hydrology Section Newsletter

As a 2019 American Geophysical Union (AGU) Hydrology Section Fellow, Dr. Beth Parker was asked to reflect on the events that have lead to the person she is today, not only to inform the hydrology community but to inspire early career scientists to understand the different paths that a Fellow may take. Starting from an early appreciation for water and soil quality fueled by growing up on a dairy and cash-crop farm, Dr. Parker describes the value of field-based teaching and interdisciplinary work, and her career experience in both industry and academia. Read Dr. Parker’s article here.

The AGU will present and pay tribute to the 2019 Union Awardees, Fellows, Medalists and Prizes recipients tonight, at the AGU Fall Meeting, Honors Ceremony in San Francisco. The ceremony is open to the public and will be followed by a champagne reception.

G³⁶⁰ Presents DFN Approach to Swedish Trade Organization

On October 24, G³⁶⁰ Senior Research Engineer & Hydrogeologist, Steven Chapman, along with Erik Bergstedt (Geological Survey of Sweden, SGU) and Janna Svensson (Sweco) presented to members of the Swedish National Trade Organization, Nätverket Renare Mark (www.renaremark.se). The meeting was comprised of consultants, local and regional environmental authorities, community stakeholders, and contractors in Sweden.

Presentations were given to two groups (20 participants each) followed by site tours of a former dry cleaner site in Helsingborg, where ongoing G³⁶⁰ research activities including rock core sampling, use of FLUTe liners for sealing boreholes, A-DTS testing and multilevel installations were showcased. Carlos Maldaner and Ryan Kroeker of G³⁶⁰ participated in the field demonstrations along with Lina Ingelstedt Frendberg of Sweco.

G³⁶⁰ is collaborating with the SGU and their consultant Sweco on applying the DFN field investigation approach at the Helsingborg site, where presentations like this are organized to facilitate technology transfer as a requirement by the Swedish EPA.

In thanks for our participation, event participants from the Swedish National Trade Organization network provided a donation on behalf of the G³⁶⁰ Group, SGU, and Sweco to WaterAid (www.wateraid.se), whose mission is to change the lives of the world’s poorest and most marginalized people by improving access to clean water, sanitation and hygiene.

More details of the event can be found on the Nätverket Renare Mark events page.
