First, you need to determine what is actually leaking near the pump. At the bottom of the water pump is a weep hole. Coolant will leak from it if the seal or bearing goes bad in the pump. Check that. Next, the brown substance could be dirty coolant. If you are getting it on the windshield, that is odd. However, I would recommend checking for a leaking intake manifold. Please keep in mind, if you are adding coolant, make sure to use the correct type for your vehicle.
