Is the underneath of my car being wet a serious problem.

What is your question?

I accidentally hit a curb and upon looking underneath the car, the front right passenger side near the front wheel and along a metal frame was wet. The liquid was blackish and sludgy. There was also a distinct stench that I cannot describe but it is not gasoline. When lifting up the hood, The power steering container is wet and there seems to be the same black liquid on the alternator. The left driver side is completely dry and no air conditioning was used.

What makes this problem better or worse?

Has not been long enough to see it get worse or better.

How long has your 2005 Honda Accord had this problem?
