Came home and found pools of water in my basement, it surrounds my furnace and water heater.. It seems to me that it is coming from my furnace, could this be? I didn't know water could come from my furnace. How can I fix? I don't know too much about this type of thing, so if you could tell in layman terms would be greatly appreciated.

Another item, I know that a "pump" sits next to my furnace and water heater, I checked this pump to see if there is any water coming from it, there wasn't.

I have vacumed up the water and have a dehumidifier running right now.

Please help>
