White space on right side of mobile site

Hello,

Kind of new to posting my own issues as I have been able to resolve a bunch by reading all of the helpful threads. Unfortunately, this time i have no such luck.

I am working on a site http://www.rainbowsreachinc.com

And for some reason there is a white space on the right side of the mobile site. (Viewing on a Galaxy s5)

From my reading I understand that this could be a set sizing issue causing my responsive site to not function properly. Is this my issue?

I have tried adjusting sizing, padding, margins, width etc in inspect element. I was able to increase and decrease the size of the content but that white space never moves. If enlarge the content it enlarges behind that white space.

Any help would be greatly appreciated.
