Background Check Alcohol Charges

Received and signed offer from a BB. I am currently waiting on background check to be completed before I start my internship. My only concern is that I ended up disclosing 2 charges on my employment application that I had in the past: - one underage drinking when I was a minor - one public drunkenness charge 3 years ago. I ended up disclosing it, just to be safe, even though they are not considered felonies or misdemeanors. I was wondering, if my alcohol charges could potentially result in a offer revocation. I'm starting in less than a month and really worried. Any thought or comment would be helpful. Thank you.
