Some water well facts
- Dug Wells - pose the highest risk of allowing drinking water supply contamination because they are shallow and often poorly protected from surface water. A dug well is a large diameter hole (usually more than 2 feet wide), which is often built by hand.
- Bored Wells - are constructed using an earth auger, usually up to 2 feet in diameter. Concrete is the most common casing material. These wells are typically hallow (less than 60 feet) and thus tend to be susceptible to surface contamination. These wells pose a moderate to high risk of contamination and are the first to go dry in a drought.
- Driven point (sand point) wells - which pose a moderate to high risk, are constructed by driving assembled lengths of pipe into the ground. These wells are normally smaller in diameter (2 inches or less) and less than 50 feet deep. They can only be installed in areas of relativity loose soils, such as sand.
- Drilled Wells - cover all other types of wells, including those constructed by a combination of jetting and driving. Drilled wells fro farm use are commonly 4 to 8 inches in diameter and when properly constructed pose a relatively low risk of contamination.
- 75% of Americans are chronically dehydrated. This likely applies to half the world's population.
- In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger.
- Even MILD dehydration will slow down one's metabolism as much as 3%
- One glass of water shut down midnight hunger pangs for almost 100% of dieters studied in a University of Washington study.
- Lack of water is the number one trigger of daytime fatigue.
- Preliminary research indicates that 8-10 glasses of water a day could significantly ease back and joint pain for up to 80% of sufferers.
- A mere 2% drop in body water can trigger fuzzy short-term memory, trouble with basic math, and difficulty focusing on the computer screen or printed page.
- Drinking five glasses of water daily decreases the risk of colon cancer by 45%, it can slash the risk of breast cancer by 79%, and one is 50% less likely to develop bladder cancer.
