If you don't get a favorable response or are unclear about the test results, contact your local health department for clarification or call the EPA Safe Water Hotline at (800) 426-4791 or e-mail hotline-sdwa@epamail.epa.gov and ask for information about EPA standards (also see their web site, http://www.epa.gov/OGWDW/index.html). The Safe Drinking Water Act requires periodic updating of EPA monitoring standards, but there has been no update since October of 1996. When calling the EPA, ask for a complimentary copy of the booklet: WATER ON TAP: A Consumer's Guide to the Nation's Drinking Water.
One might think that rain or snow would be exempt from contamination, but when water vapor condenses out of the atmosphere it always does so on a particle of dust which releases substances into the water, and even the purest air contains carbon dioxide which dissolves to form carbonic acid. Except in highly polluted atmospheres, the impurities picked up by snow and rain are too minute to be of concern.
About Covenant Filtration :About two-thirds of the weight of an adult human consists of water. About two-thirds of this water is located within cells, while the remaining third consists of extracellular water, mostly in the blood plasma and in the interstitial fluid that bathes the cells. This water, amounting to about five percent of body weight (about 5 L in the adult), serves as a supporting fluid for the blood cells and acts as a means of transporting chemicals between cells and the external environment. It is basically a 0.15M solution of salt (NaCl) containing smaller amounts of other electrolytes, the most important of which are bicarbonate (HCO3–) and protein anions.
Ice, like all solids, has a well-defined structure; each water molecule is surrounded by four neighboring H2Os. two of these are hydrogen-bonded to the oxygen atom on the central H2O molecule, and each of the two hydrogen atoms is similarly bonded to another neighboring H2O.
10. Try water for weight loss. Can you drink more and weigh less? Yes, thanks to a biological quirk that is friendly to fat reducers. Your body is a natural water heater. When you drink water, which is nearly always a lower temperature than your body, the body expends energy (and therefore calories) to bring the water up to its own temperature. So you're not only drinking a non-caloric beverage, you're burning calories! That's a darn good drinking deal. Your body can burn around 100 calories a day using energy to heat a gallon of cool water that you drink. That translates into nearly a pound of fat loss in a month. Beware of any weight loss programs that advise drinking less water. Water contributes to health by helping the kidneys flush toxins out of the body. When the kidneys are working optimally, other organs of the body, especially the liver, are more in balance.

"WATERING" YOUR GROWING CHILD
Covenant Filtration Group Offerts : It has recently been found (Langmuir 2003, 19, 6851-6856) that freshly distilled water takes a surprisingly long time to equilibrate with the atmosphere, that it undergoes large fluctuations in pH and redox potential, and that these effects are greater when the water is exposed to a magnetic field. The reasons for this behavior are not clear, but one possibility is that dissolved O2 molecles, which are paramagnetic, might be involved.

* Avoid junk juice "drinks," which contain a tiny bit of juice and a lot of added sweeteners. Instead, use "100 percent juice."
* Avoid carbonated drinks which can leave the athlete feeling bloated.
* Before the game, instead of soft drinks, drink plain water. Besides the sugar in the soft drink slowing the absorption of much needed water, it could trigger low blood sugar during the game, just what the athlete doesn't need.
* Instead of commercial sports drinks, you could make your own. Juices, such as apple, orange, or grape are an excellent base for sports drinks, since they contain both glucose and fructose sugars, as well as potassium, which is lost with sweating. Fructose sugar is one of the best carbohydrates for replacing used up muscle glycogen stores. Add one teaspoon of salt (to replace the sodium lost while sweating) to a quart of dilute juice, and you've made your own sports drink.
* The best time to drink commercial or homemade sports drinks is during exercise, since the carbs in the drink do not cause high blood sugar fluctuations because insulin is not secreted during exercise. (Drinking a high- sugar drink prior to exercise may trigger insulin and lead to hypoglycemia in the middle of the game.)
* As a general rule, sip one quart of cool rehydration liquid per hour of strenuous exercise.
* It's better to drink liquid calories rather than solid food during exercise, since solids remain in the stomach longer and delay the absorption of the much- needed carbs and water.
