The use of pesticides and herbicides has become so excessive that they are now commonly found in household tap water with alarming frequency. A 1994 study of 29 major U.S. cities by the Environmental Working Group found that all 29 cities had traces of at least one weed killer in the drinking water. The report titled Tap Water Blues went on to say that Millions of Americans are routinely exposed to one or more pesticides in a single glass of tap water. These first ever tap water testings found two or more pesticides in the drinking water of 27 of the 29 cities, three or more in 24 cities, four or more in 21 cities, five or more in 18 cities, six or more in 13 cities and seven or more pesticides in the tap water of five cities. In Fort Wayne Indiana, nine different pesticides were found in a single glass of tap water! As a startling side note, it was reported that in these 29 cities 45,000 infants drank formula mixed with tap water containing weed killers and that over half of these infants were swallowing 4 to 9 chemicals in every bottle! This is precisely why one should drink only filtered water. Water filters and Water purifiers such as those found at Berkey water can prevent one’s exposure to contaminated water and promote good health.
