I think there is a great interest in the proposed actions and groundwater is a growing field of research in great part due to the EU regulations and future tackling of CC effects. I'm particularly interested in e-courses on groundwater ecology, environmental management and translation of scientific outputs into the industrial management context.
Chris Dede's work at Harvard created wonderful immersive environments for older high school students to study the effects of environment on ecosystems.

Guidance on groundwater modeling is better when received 1 on 1 by an instructor because it is more difficult to pass on experience through these online classes that generally do not provide a way to teach the real experience and what to do in specific real problems.
