A common leak on the 3.8 engine is the upper intake manifold. The gasket itself can go bad on it’s own, but sometimes the plastic intake will become brittle and crack around the gasket. Do not delay having the leak inspected. Water can both leak outside the engine and into the oil. Sometimes it can leak into the cylinders and hydrolock the engine. A qualified mechanic from YourMechanic can come out and diagnose the coolant leak and make the proper recommendations.
