blog postsBottled Water vs. Tap WaterOct 29, 2010 11:00 am971 views The only reason to buy bottled water is for the convenience (and possibly taste). In Illinois, homeowners who have their own wells often buy drinking water due to quality problems with their well water. But if you get your drinking water from a public water supply, that water is regulated by the Environmental Protection Agency (EPA), which has developed drinking water standards for more than 100 contaminants. Bottled water, on the other hand, has been defined as food and is regulated by the Food and Drug Administration (FDA), using different standards than EPA. FDA's regulations are defined as Current Good Manufacturing Practices (CGMPs), such as using sanitary conditions, protecting water sources, and analyzing for a smaller set of contaminants than EPA requires. This is not to say that bottled water is unsafe, but its quality is no better than tap water.Why study water quality?Oct 21, 2010 4:30 pm755 views This seems like an obvious question. We need to understand water quality in order to protect our health, and also the health of ecosystems. Those, of course, are the main reasons we are interested in water quality, so that we make sure our drinking water is safe and we are not damaging the environment.Illinois Water 2010 ConferenceOct 15, 2010 11:00 am256 views Last week (October 6-7, 2010) was the biennial Illinois Water conference, hosted by the Illinois Water Resources Center at UI.
