An Issue Worth a Thought: Your Water Supply and Why You Don’t Need Bottled Water
Years ago, we began learning about possible contaminants to our water supply through nightmare stories like “Love Canal” which quickly got embedded into our lexicon. I looked into some of the recent issues about water quality and decided to install an RO (stands for reverse osmosis; reverse because normally the dissolved material (solute) goes through a filter, like a semipermeable membrane but with RO, its the solvent (water) that goes through leaving everything else behind…hence ‘reverse’) water filter attached to our normal water supply. An RO filtration system is based on a fine semipermeable membrane that allows water through but very little else. Then, when combined with a charcoal filter, you have a very high quality source of water, because, to begin with, our water supply is generally safe. But, as you know, more and more bottled water is being sold and it seems as though people are under the impression that our water supply is not safe, so that bottled water is the way to go. But, numerous reports indicate that this is not the case and that, quite often, the bottled water you see labeled as “spring water” is more contaminated than your tap water. Some brands do carry bottled, RO water and you have some assurances about that water quality because an RO filter system can take some very ugly water and make high quality drinking water out of it, but it is usually far more expensive.
