Very nice the three videos, very clear and useful in nay language, cause the subtitles work reasonably well. I am showing and recommending these videos in my classes in Spain (Master of Environmental Engineering). More like these, developing cases of GW pollution and contaminant transport, would be great.
At 4:51 my bf sent me a screenshot of it and it sounded familiar the last name it clicked n it said dumbass which I thought was hilarious 😂 no offense though
