Why do I have a puddle building under my water pump but my guages all read norma

water pump might be going bad do a preasure test it will pin point the leak

If the puddle under the water pump is coolant the gauges will read normal until the coolant level gets low enough to cause overheating or a low coolant indicator (not all vehicles have this) to come on. I agree with the previous answer, pressure test it, make sure to look at any hoses near the pump. If you are not sure where the coolant is coming from have it check by a shop.
