Dowsing and clean water

Dowsing 

From Wikipedia, the free encyclopedia

Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, gravesites,^[1] and many other objects and materials, as well as so-called currents of earth radiation (ley lines), without the use of scientific apparatus. Dowsing is also known as divining (especially in reference to interpretation of results),^[2] doodlebugging^[3] (particularly in the United States, in searching for petroleum^[4]) or (when searching specifically for water) water finding, water witching or water dowsing.^[5] There is no accepted scientific rationale behind dowsing, and there is no scientific evidence that it is effective.

A Y- or L-shaped twig or rod, called a dowsing rod, divining rod (Latin: virgula divina or baculus divinatorius), a "vining rod" or witching rod is sometimes used during dowsing, although some dowsers use other equipment or no equipment at all.

Dowsing appears to have arisen in the context of Renaissance magic in Germany, and it remains popular among believers in Forteana or radiesthesia.^[6]

History

Dowsing as practiced today may have originated in Germany during the 15th century, when it was used in attempts to find metals. As early as 1518 Martin Luther listed dowsing for metals as an act that broke the first commandment (i.e., as occultism).^[7] The 1550 edition of Sebastian Münster's Cosmographia contains a woodcut of a dowser with forked rod in hand walking over a cutaway image of a mining operation. The rod is labelled "Virgula Divina – Glück rüt" (Latin: divine rod; German "Wünschelrute": fortune rod or stick), but there is no text accompanying the woodcut. By 1556 Georgius Agricola's treatment of mining and smelting of ore, De Re Metallica, included a detailed description of dowsing for metal ore.^[8]

In 1662 dowsing was declared to be "superstitious, or rather satanic" by a Jesuit, Gaspar Schott, though he later noted that he wasn't sure that the devil was always responsible for the movement of the rod.^[9] In the South of France in the 17th Century it was used in tracking criminals and heretics.^[10] Its abuse led to a decree of the inquisition in 1701, forbidding its employment for purposes of justice.^[11]

An epigram by Samuel Sheppard, from Epigrams theological, philosophical, and romantick (1651) runs thus:

Virgula divina.

"Some Sorcerers do boast they have a Rod,

Gather'd with Vowes and Sacrifice,

And (borne about) will strangely nod

To hidden Treasure where it lies;

Mankind is (sure) that Rod divine,

For to the Wealthiest (ever) they incline."

Dowsing was conducted in South Dakota in the late nineteenth and early twentieth centuries to help homesteaders, farmers, and ranchers located water wells on their property.^[12]

In the late 1960s during the Vietnam War, some United States Marines used dowsing to attempt to locate weapons and tunnels.^[13] As late as in 1986, when 31 soldiers were taken by an avalanche during an operation in the NATO drill Anchor Express in Vassdalen, Norway, the Norwegian army attempted to locate soldiers buried in the avalanche using dowsing as search method.^[14] 16 soldiers died.

Dowsing rods

Traditionally, the most common dowsing rod is a forked (Y-shaped) branch from a tree or bush. Some dowsers prefer branches from particular trees, and some prefer the branches to be freshly cut. Hazel twigs in Europe and witch-hazel in the United States are traditionally commonly chosen, as are branches from willow or peach trees. The two ends on the forked side are held one in each hand with the third (the stem of the "Y") pointing straight ahead. Often the branches are grasped palms down^{[citation needed]}. The dowser then walks slowly over the places where he suspects the target (for example, minerals or water) may be, and the dowsing rod supposedly dips, inclines or twitches when a discovery is made. This method is sometimes known as "Willow Witching".

Many dowsers today use a pair of simple L-shaped metal rods. One rod is held in each hand, with the short arm of the L held upright, and the long arm pointing forward. When something is found, the rods cross over one another making an "X" over the found object. If the object is long and straight, such as a water pipe, the rods will point in opposite directions, showing its orientation. The rods are sometimes fashioned from wire coat hangers, and glass or plastic rods have also been accepted. Straight rods are also sometimes used for the same purposes, and were not uncommon in early 19th century New England.

In all cases, the device is in a state of unstable equilibrium from which slight movements may be amplified.^[15]

Other equipment used for dowsing

A pendulum of crystal, metal or other materials suspended on a chain is sometimes used in divination and dowsing. In one approach the user first determines which direction (left-right, up-down) will indicate "yes" and which "no" before proceeding to ask the pendulum specific questions, or else another person may pose questions to the person holding the pendulum. The pendulum may also be used over a pad or cloth with "yes" and "no" written on it and perhaps other words written in a circle. The person holding the pendulum aims to hold it as steadily as possible over the center and its movements are held to indicate answers to the questions. In the practice of radiesthesia, a pendulum is used for medical diagnosis.

Scientific appraisal

A 1948 study tested 58 dowsers' ability to detect water. None of them was more reliable than chance.^[16] A 1979 review examined many controlled studies of dowsing for water, and found that none of them showed better than chance results.^[5] A 2006 study of grave dowsing in Iowa reviewed 14 published studies and determined that none of them correctly predicted the location of human burials, and simple scientific experiments demonstrated the fundamental principles commonly used to explain grave dowsing were incorrect.^[17]

More recently a study^[18] was undertaken in Kassel, Germany, under the direction of the Gesellschaft zur Wissenschaftlichen Untersuchung von Parawissenschaften (GWUP) [Society for the Scientific Investigation of the Parasciences]. The three-day test of some 30 dowsers involved plastic pipes through which water flow could be controlled and directed. The pipes were buried 50 centimeters under a level field, the position of each marked on the surface with a colored strip. The dowsers had to tell whether water was running through each pipe. All the dowsers signed a statement agreeing this was a fair test of their abilities and that they expected a 100 percent success rate. However, the results were no better than chance.

Suggested explanations

Early attempts at a scientific explanation of dowsing were based on the notion that the divining rod was physically affected by emanations from substances of interest. The following explanation is from William Pryce's 1778 Mineralogia Cornubiensis:

The corpuscles ... that rise from the Minerals, entering the rod, determine it to bow down, in order to render it parallel to the vertical lines which the effluvia describe in their rise. In effect the Mineral particles seem to be emitted from the earth; now the Virgula [rod], being of a light porous wood, gives an easy passage to these particles, which are also very fine and subtle; the effluvia then driven forwards by those that follow them, and pressed at the same time by the atmosphere incumbent on them, are forced to enter the little interstices between the fibres of the wood, and by that effort they oblige it to incline, or dip down perpendicularly, to become parallel with the little columns which those vapours form in their rise.

Such explanations have no modern scientific basis. A 1986 article in Nature included dowsing in a list of "effects which until recently were claimed to be paranormal but which can now be explained from within orthodox science."^[19] Specifically, dowsing could be explained in terms of sensory cues, expectancy effects and probability.^[19] Skeptics and some supporters believe that dowsing apparatus has no power of its own but merely amplifies slight movements of the hands caused by a phenomenon known as the ideomotor effect: people's subconscious minds may influence their bodies without their consciously deciding to take action. This would make the dowsing rods a conduit for the diviner's subconscious knowledge or perception; but also susceptible to confirmation bias.^[20][21]

Soviet geologists have made claims for the abilities of dowsers,^[22] which remain unverified by any credible scientific means. Some authors suggest that these abilities may be explained by postulating human sensitivity to small magnetic field gradient changes.^[23][24][25]

Betz Controversy

In a study in Munich 1987–1988 by Hans-Dieter Betz and other scientists, 500 dowsers were initially tested for their "skill" and the experimenters selected the best 43 among them for further tests. Water was pumped through a pipe on the ground floor of a two-storey barn. Before each test the pipe was moved in a direction perpendicular to the water flow. On the upper floor each dowser was asked to determine the position of the pipe. Over two years the dowsers performed 843 such tests. Of the 43 pre-selected and extensively tested candidates at least 37 showed no dowsing ability. The results from the remaining 6 were said to be better than chance, resulting in the experimenters' conclusion that some dowsers "in particular tasks, showed an extraordinarily high rate of success, which can scarcely if at all be explained as due to chance ... a real core of dowser-phenomena can be regarded as empirically proven."^[26]

Five years after the Munich study was published, Jim T. Enright, a professor of physiology who emphasised correct data analysis procedure, contended that the study's results are merely consistent with statistical fluctuations and not significant. He believed the experiments provided "the most convincing disproof imaginable that dowsers can do what they claim",^[27] stating that the data analysis was "special, unconventional and customized". Replacing it with "more ordinary analyses",^[28] he noted that the best dowser was on average 4 millimeters out of 10 meters closer to a mid-line guess, an advantage of 0.0004%, and that the five other "good" dowsers were on average farther than a mid-line guess. He further pointed out that the six "good" dowsers did not perform any better than chance in separate tests.^[29]

Commercial and "high-tech" dowsing devices

A number of devices resembling "high tech" dowsing rods have been marketed for modern police and military use: none has been shown to be effective.^[30] The more notable of this class of device are ADE 651, Sniffex, and the GT200.^[31][32] A US government study advised against buying "bogus explosive detection equipment".^[30]

Devices:

• Sandia National Laboratories tested the MOLE Programmable System manufactured by Global Technical Ltd. of Kent, UK and found it ineffective.^[31]

• The ADE 651 is a device produced by ATSC (UK) and widely used by Iraqi police to detect explosives.^[32] Many^[32][33] have denied its effectiveness and contended that the ADE 651 failed to prevent many bombings in Iraq. On 23 April 2013, the director of ATSC, Jim McCormick was convicted of fraud by misrepresentation.^[34] Earlier, the British Government had announced a ban on the export of the ADE-651.^[35]

• SNIFFEX was the subject of a report by the United States Navy Explosive Ordnance Disposal that concluded "The handheld SNIFFEX explosives detector does not work."^[36]

• Global Technical GT200 is a dowsing type explosive detector which contains no scientific mechanism.^[37][38]

Poster's comments:

            I was trained in dowsing by my mother's father.

            Locally, he was often hired by local middle Tennessee country people to dowse for water well digging sites. His hit rate was 100% as I recall. He died in 1978.

            We often used peach forks as well as weeping willow forks to dowse with.

            He taught other progeny, and his techniques worked for some of them, too. He even taught a cousin to back off from the best well digging site, and the distance would equal to well depth to detect water.

            Dowsing doesn't work for everyone.

            Hence I understand the controversy on the subject of dowsing.

            His main area for dowsing was limestone country, were the water generally flows underground in veins vice existing in pools.

            The probability of hitting water is a decent alternative to consider.

            I now live about 100 miles away, and dowsing is still used as a method in east Tennessee, to include searching for minerals, like even oil and gas. Though many dowsers also use more modern instruments, like gamma ray detectors, to provide a second opinion when it comes to mineral drilling sites.

            I went to GaTech, and am not very religious, but dowsing is something that has worked for me. I just can't explain it to my satisfaction.

            I suspect if times get hard, then dowsing will come back, and probably many "dowsers" will be "snake oil" types. Let the buyer beware.

            Getting clean water to cook and clean with, and having a waste water system, is a big deal for our human survival and good (preventive) health.

            Where I live in east Tennessee on the Cumberland Plateau, most water drilling efforts fail. While many find water, it is often sulfur (rotten egg) smelling, and not used for human consumption.

            When I lived in southern California, the well water we (my wife and I) had then was very "mineral" intensive, like we had to get a once a month service to remove the "minerals" from the water. This room to do this was even built into military housing units. To avoid this service often meant clogged shower heads and failing washing machines. The human equivalent would be like having clogged arteries.
