In a medium Dutch oven, bring 4 cups water and milk to a boil over medium-high heat. Stir in grits, salt, garlic powder, pepper, and paprika. Reduce heat to medium-low; simmer, stirring frequently, until grits are tender, 20 to 40 minutes. Add cheeses, and stir until smooth. Keep warm until serving.
