standing water behind the brake booster

[texomawaves]

Could this be condensate collecting from the air conditioning component (dryer?) ? I suspect leaves clogging a drain hole somewhere in there. The standing water is hard to see in the picture. Any solution?

clean the drain hole right next to the battery.

here is the location.
in this picture the battery is removed, but it doesn't have to be.

There are multiple drain holes in that front compartment - firewall area. In that picture there should also be an arrow in the left side near that wire loom - if I am not mistaken.
