In the City:
Did you know that our public water systems only test for a limited number of dangerous chemicals? It is true — most water systems just measure levels for the ones that the EPA mandates.
Did you realize that you could be buying basic tap water in a bottled form at the grocery store? There are no guidelines to require bottlers to tell you what you are buying!
In the Country:
If you live on a farm or in a farming community and get your water from a well, your water may need to be treated for farm chemicals that leach into the water, as well as problems that come from the soil and other challenges depending on the local water table and supply.
