    Science is confusing.
    Okay so, I'm in 8th grade and I have a worksheet on Freshwater pollution. It tells me about it on the front, I got the first half of the questions, but there's a question that I don't even see the answer to on the front?

    "How can water pollution be cleaned up naturally?"

    I think the answer is "rock and sand of an aquifer naturally filter and purify groundwater."

    But I don't know if it's right, and we get graded on our homework.

    Anyone help?
