Remove Whitespace Between Content and Footer

I have searched the forum and have tried all the fixes for this to no avail. Maybe someone can address this again.

I have an embedded video on my contact page. I want to eliminate the whitespace between the video and the footer. Nothing I am trying is working. ?? Not having the issue on the home page but this is a project i just took over from someone else so not sure what they did.

Can one of you WP wizards offer a solution? Here is the link to the page. https://alpheuswaterfund.com/contact-us/

Thank you so much.
