car is leaking a clear substance, need help!

Hi guys, have a quick question - I noticed something dripping from the passenger side door (left door - driver side for US cars) and was wondering if it would be of any concern - Dad said it's just condensation because it's humid today but i don't know and want to be sure.
Underneath doesn't look like there's any damage but might have been a scrape from a speed bump or something?

The liquid is clear and water like and dripping very slowly - no smell but it's hard to tell if it is actually water because most of its on the ground.

Some pics here : Photo Album - Imgur Pretty hard to get under - but theres a gash that looks like it's a concern but i have no idea how that could have happened..

Thanks for the help!
