Naturally can be used as a synonym for normally, so its use is ok here. In fact, you can't move "naturally" into the prepositional phrase as it changes what the word modifies from "found" to "balanced". Analogy:
The mineral is found naturally in calm water
The mineral is found in naturally calm water (how can something be naturally calm?)
