Melody,
I am not aware of any use of coffee grounds for purification of water. Water can be purified with carbon filters. Passing water through coffee grounds most likely will just add compounds (nutrients) in the grounds into the water and not purify the water. However, coffee grounds could be beneficial to plants as a fertilizer. You might try an experiment of getting small plants that are the same, add no grounds to 3 plants, a little coffee to 3 plants, and allot of coffee to 3 plants and compare resutls after some time (eg 1 month).
