You may just have a faulty trackpad. The possibility of water exposure means it could be water damage. A little water is all it takes, and the damage is done if not dealt with immediately.
You could try replacing the trackpad. If you can do it youself the cost might be worth the chance that is all it takes. But there's the risk there is more damage than just a bad trackpad.
