I love to read and study about groundwater. It drives me. Maybe because its has so much history and its very very important. Maybe because groundwater can be there for more than 20 thousand years. I always say think of groundwater as saving account. You save it and sometimes use it but If you empty it you end up with no saving. (Or something like that)
When I was applying for masters I really wanted to work on groundwater and surface water interactions. That didn’t happen to me but I got to talk a lot about it and give a lot of presentations on groundwater!
