i'd want to know what water company he used to get his water from. I call be on that part. There is no way that they would get water from the lake, process it, and deliver it to him in 2 days. I don't know of any companys that get water from lake erie anyways... granted I am not an expert on water companies, but thats still way too fast.
I'd ask him for reciepts for the water then contact the company and see if they get any of their water from the lake.
