How to change static information above footer found on each page

Hi,
I am a total non-web-design person, so much so that I am struggling with finding the right words to describe what I need help with. So, my employer’s website has what looks like a banner running across the bottom of each page ( https://www.northamptonprevent.org). It is a wide blue banner with a disclaimer and our contact information. I have been poking around WordPress, learning as I go and found out that the information I need to change ( contact information) is not held within the footer. So I am not sure where the information is stored or how to access it. All I need to do is change the contact info but do not know how to find it.

My first thought is maybe it is a template somewhere, but I have been unsuccessful in figuring out where.

Can anyone help?
Thanks,
Ananda
