If you would like to avoid the toxic contaminants commonly found in city water such as: chlorine, fluoride, petrochemicals, dioxins, lead, mercury, aluminum and radioactive isotopes such as iodine 131, radium 226 and 228, here is a list of natural water sources in Wisconsin. Most of which are free to the public and some even list the TDS, total dissolved solids and pH level!
If you're thinking to yourself, "I only drink bottled water so I'm good," you may be surprised to know that the bottled water industry is a completely UNREGULATED industry, meaning they don't require any sort of testing or proof of quality on their products before introducing them to consumers. Most companies such as Coca Cola, Pepsi and Nestle source their water from municipal sources, containing all of the previously mentioned contaminants.
And just to ensure optimal quality, you can always purchase an Ozone Generator which will effectively remove any viruses, bacteria and other potential pathogens. Ozone Generators also work to detoxify all meats, fish and poultry. They also remove pesticides, herbicides, insecticides and artificial waxes from your produce. http://www.air-zone.com/water.html
