New Upfront Interface: You might have noticed we have new directory pages (sessions, animations, simulations, videos and spreadsheets) so you can get to where you want to go faster and easier.

New Pricing: We are now offering discount pricing to college students and their instructors and extending the license period to one year. You need to have your instructor contact us for a discount code and have a current college id.

New Downloads: We have revised the course content download (which is yours to keep) so you get the course as a pdf portfolio.

New Spreadsheets: The pumping test analysis spreadsheet with Excel Solver in Session 14c has been revised. A new batch Kd test analysis spreadsheet has been added.

New Simulation: Two new simulations have been added: a Water Level Sounder and a Batch Kd Test.
