What is the pH of water with fresh squeezed lemon in it?

Obviously the pH of water is a neutral 7 and lemons are acidic so I would imagine that water with fresh squeezed lemon in it would be mildly acidic, but everywhere I read says that lemon water is alkaline. Is this true or are they wrong?

Here is one of the sites http://www.energiseforlife.com/list_of_alkaline_foods.php
Trevor I think you are completely over thinking this. On that link there are both lemons and limes listed as alkaline fruits, and that is why I was confused, because I have always known that lemons and limes (the fruits) are acidic. This was not meant to be a confusing question and obviously you misread it and/or over thought it.
