Purchased 8 case's of PurAqua Spring Water...Today noticed that some brown particles floating in an sealed and closed bottle...Had consumed about half the case of water (24 bottles). The remaining bottle all had the particles floating in them...What is this? Is the water safe to drink? I looked at another case of water...and it apears to be okay or the particles are to small to be seen...Is there quality control during the bottling process? I know the water is cheap as it should be but it should also be safe to drink by anyone. read full review »
