The United Nation’s Agenda for Sustainable Development includes an acknowledgment that ending poverty must go hand-in-hand with strategies to improve health and inequality. Drinking water quality is a key factor affecting both of these, but finding solutions that provide access to clean water for communities in small, remote, and resource-poor parts of the world is difficult. For the past two decades, Dr. Kumiko Oguma has been exploring a variety of water-related challenges in underdeveloped areas in Asia. Projects include determining drinking water health risks following flooding in Jakarta, deterioration of water quality in distribution systems in Kathmandu, and identifying the potential source of a mysterious chronic kidney disease in Sri Lanka. In this talk, Prof. Oguma will focus on a recent initiative to install solar-powered ultraviolet light systems in schools in the Philippines. Ultraviolet light is known to be an excellent drinking water disinfectant, but electrical supply and longevity of the UV light source have been obstacles in the past. Her current research is exploring LED sources for UV, which promise to be more robust than traditional lamps, requiring less maintenance and intervention. The presentation will discuss the advantages and disadvantages of such an approach, and highlight where this technology might best be applied moving forward.

KUMIKO OGUMA is an Associate Professor in the Department of Urban Engineering at the University of Tokyo. Her primary research interest is in the use of UV-based technologies for the control and prevention of waterborne infectious diseases. Prof. Oguma has spent considerable time investigating water-related health issues in developing countries in South and Southeast Asia. She currently serves as the Asia-Pacific Regional Vice President of the International Ultraviolet Association.

Distinguished Lecture Series: David Keith, Harvard University @ Bahen Centre, Room BA1170



I will review the science and technology of solar radiation modification. Estimates of the risks and efficacy of solar geoengineering are deeply uncertain. Accurate physically-based models along with laboratory and in situ experiments will be needed to improve estimates of the efficacy and risks of proposed solar geoengineering methods. As an example, I will discuss out laboratory experiments and plans for perturbative outdoor experiments. Governance poses the greatest challenge for solar geoengineering. Finally, I will sketch how solar geoengineering might fit together with emissions cuts, carbon removal, and adaptation in a coherent climate strategy.

Distinguished Lecture Series: Silvio Baldassarra
Mar 25 @ 5:00 pm – 6:30 pm


TITLE: SkyDome Open and Shut Case


Silvio Baldassarra, Chairman of NORR Architects & Engineers Limited
Silvio Baldassarra is an Architect with 45 years of experience in design and management of large complex projects in commercial, government, hospitality, sports and transportation sectors.  He was the project architect responsible for the retractable roof of SkyDome (Rogers Centre) in Toronto when he started with NORR in 1986 and today is Chairman of NORR Architects & Engineers Limited. Abstract
“Open the 11,000 ton retractable roof by moving three roof panels in 20 minutes”.  On June 3, 1989 the world’s first retractable roof, multi-use stadium, SkyDome (Rogers Centre) opened in Toronto.  It was a Canadian architectural and engineering innovation, designed by architect, Rodrick Robbie and engineer, Mike Allen.  As, the roof architect I spent 3 years working with the two visionaries to develop the roof design including; structure, movement systems, seals, catwalks and stadium lighting.

Thirty one years later, I will share our story of the design/build solution of the first and most successful retractable roof innovation in the world.

The retractable roof of SkyDome was the first of its kind in the world.  Four separate roof panels weighing 11,000 tons and 8 acres in area.  Three of the panels are required to move and stack on the one positioned in the north end to expose 100% of the playing field and 91% of the stadium seats.  The building technology is adapted from fail safe railway technology.  The adaption is innovative when moving 11,000 tons of roof.  The design/build team worked through solution after solution including many failures through testing in labs including University of Toronto under the direction of Professor Jeffrey Packer, before arriving at the final technology solution for SkyDome.

The presentation will start with the competition criteria which was simple “open and close the roof in 20 minutes”.  The concept proposed during the design competition was not fully engineered and was defined in concept only as 4 panels, three of which moved over the fourth.  The presentation will describe the 3 years that followed through the engineered design/build process of solutions for:

  • Building support structure for the roof panels
  • Roof structure connection to the building
  • Roof movement systems analyzed and final chosen
  • Roof seals extreme movement laterally and horizontally and seals invented for SkyDome
  • -Maintenance of roof movement systems in the roof and on the building support
  • Stadium lighting systems which are uniquely fixed to the building sculpted under the retractable roof.

TITLE: Trouble Ahead, Trouble Behind: Acid Mine Drainage and Climate Change in the Rocky Mountains

Co-hosted with CivMinRyerson, and York


Diane McKinght, University of Colorado

Diane M. McKnight is a Professor in the Department of Civil, Environmental and Architectural Engineering, a member of the Environmental Engineering program faculty and a Fellow of the Institute of Arctic and Alpine Research at the University of Colorado. Her research focuses on the coupling of hydrology and water quality in streams and lakes, and the consequences for aquatic ecosystems and water supplies. She began her career as a research hydrologist with the U.S. Geological Survey, studying the biogeochemistry of lakes in the blast zone of Mt. St. Helens and acid mine drainage streams and pristine alpine lakes in the Rocky Mountains. She participated in designing ecological aspects of the National Water Quality Assessment Program of the USGS. Since 1992, she has conducted research on stream ecosystems as part of the McMurdo Dry Valleys Long-Term Ecological Research (MCM-LTER) project in Antarctica. She has been President of the American Society of Limnology and Oceanography and editor of Journal of Geophysical Research-Biogeosciences.

In the Rocky Mountain watersheds, weathering of disseminated pyrite in the country rock and in mining workings generates acidic, metal-enriched water that drains into streams and rivers. This overall process is referred to as acid rock drainage (ARD). ARD is a long-term and pervasive environmental problem in the Rocky Mountains and the Sierras, which provide water supply for communities and agriculture throughout the south western US. Contamination has not abated since the mining boom ended about 70 years ago, largely because these contaminants are continuously generated from the exposure to oxygen of pyrite in the mine workings and tailings. Typically these streams have high dissolved concentrations of toxic metals, such as Zn, Cu, Cd and Pb, and their streambeds are covered with iron and aluminum oxides. These streams and rivers support species-poor aquatic ecosystems, and fish are typically absent. A study in an ARD stream system that drains into Dillon Reservoir, a water supply for Denver, Colorado, has found that acidity and concentrations of metals and rare earth elements have been steadily increasing in the summer and fall over the past several decades. Another trend is that mountain resorts have been pursuing a “four seasons resort” approach to adapt to changing climate, and less reliable winter snowpack for skiing. ARD thwarts these plans by constraining the use of stream water for snowmaking and impacting summer recreation, such as fishing and rafting. In addition to general environmental concerns, this situation has focused attention on remediation of abandoned mines which is inherently challenging, as illustrated by the difficulties in remediating the Gold King Mine near Durango, CO. One issue for state and federal agencies and watershed stakeholders’ groups is determining which of the many abandoned mines in a catchment are the main ARD sources, and which of these are suitable for remediation. Addressing the ARD problem in mountain catchments will require a convergent research approach that integrates understanding of hydrology, water quality and aquatic ecosystem processes within a regulatory and water resources framework.


Research focuses on interactions between hydrologic, chemical and biological processes in controlling the dynamics in aquatic ecosystems. This research is carried out through field-scale experiments, modeling, and laboratory characterization of natural substrates.
