It’s an old problem, but we’ll never be able to solve the problem unless we suppress our desire to use a lot of water, but our life is heavily reliant on water. Science and engineering can do desalination to turn saline water into fresh water, and we can secure ground water by recycling wastewater to return it to ground, but that has limitations unless people change their lifestyle. But this isn’t just for scientists and engineers, this is everyone’s responsibility to think about what can we do better." Link to the PDF of the Cover Story.

The 242nd American Chemical Society Spring National Meeting in Denver, CO, August 28-September 1, 2011. Co-organized with Dave Cole (Ohio State Univ.)

Mitigation of climate change requires immediate actions to reduce anthropogenic CO2 emissions and lessen future adverse effects. Sequestration of carbon dioxide in geological reservoirs may be a promising approach to reduce carbon dioxide emissions. However, it requires a better understanding of the geochemical, geophysical, and biological processes, all the way from the nanoscale to the field site scale and from seconds to hundreds of years. This symposium features oral and poster presentations describing multiscale and multidisciplinary advances in our understanding of more sustainable geologic CO2 sequestration. The symposium will conclude with a panel discussion on "Knowledge Gaps and Future Outlook."

Invited speakers and Panelists are Sally Benson (Stanford Univ.), Susan Carroll (LLNL), Michael Celia (Princeton Univ.), James W. Johnson (Schlumberger), Yousif Kharaka (USGS), John Kaszuba (Univ. Wyoming), and Carl Steefel (LBNL).
