I was at the beach and usually do not drink as condition of my probation but had plenty of drinks Sunday around 5 drinks Monday and 2 on Tuesday and have not drank since then as I came back from the beach and wanted to return to bring clean... My EtG test is Friday (tomorrow) at noon.. How/ will I pass?

More than 60 hours will have passed since your last drink so chances are you will be fine. There is a chance that you might have enough residual ETG/ETS in your system that you'll test positive though. Hopefully this series of mistakes will not stop you from going to the beach again soon.

When was your last drink on Tuesday? I agree that 2 1/2 days of not drinking would most likely clear the 2 drinks from Tuesday, but I worry about the build up from Sunday + Monday episodes. Even though your BAC most likely reached 0 at some point, Monday or Tuesday, the ETG would still be present for... who knows how long after. If it were closer to the 80 hour mark after the last drink, over 3 days of drinking I would be more comfortable guessing a pass.
