Well site location should first be based upon hydrogeology, but many other factors enter into play. NOTE: Much of the contents on this page has actually been adjusted from publications of Lifewater International, written by Fred Proby. Residential or commercial property owners and individuals who will be utilizing a water well will typically base their option of well location on the benefit of the site.

Almost speaking, this might not be possible, and well site choice generally involves some sort of compromise. A number of other factors to consider worrying well place ended up being really essential in our efforts to produce a dependable source of tidy, safe water. Firstly, the drill rig being utilized must have the ability to permeate the formations in the location and reach groundwater within the depth limitation of the rig.
If a well is situated far enough away from a latrine, the soil is able to filter out damaging organisms before they reach the well. To identify the minimum safe separation range in between latrine and well we need to know 3 things:1. Instructions the groundwater is moving. 2. Range between the bottom of the latrine and the water level.
Type of soil in between the bottom of the latrine and the water table. Following these guidelines (or any well website placement guidelines) will not guarantee that a well will be complimentary from bacterial contamination. The well must likewise be properly built and the well water tested to ensure the very best possible water quality.
It might be challenging to know the instructions of flow. But, groundwater in an unconfined aquifer tends to stream in the instructions that the ground slopes, and it streams from a recharge area to a discharge point. Understanding this, it will normally be much better to find a well uphill from a latrine than downhill from one.
There is clay, silt or fine sand between the bottom of the latrine and the water table. The well is located at least 15 meters from the latrine1. The well is situated at least 15 meters from the latrine.
Finer grains soils, like clay, silt, or fine sand can more easily filter out pathogens than coarse sand or gravel. So, the minimum safe separation distance is much shorter for the finer soils than it The Water Locator is for the coarse soils. In either case, if circulation instructions is known, it is best to put the well up-gradient from the latrine.
The direction that groundwater flows, as noted above, is a very important ecological factor to know. A well need to be positioned so that contamination from any source moves away from the well and not toward it.
The type of soil near the surface area is likewise essential. As pointed out, clay, silt, and fine sand can keep contaminants from reaching the groundwater. 3. Surface area waters, like streams, rivers, and ponds, might include biological, farming, or commercial contamination so wells need to be found at least 15 meters far from them.

Avoid areas that get flooded, since people can not get to the well to the well during times of high water and the well might be contaminated by floodwaters overruning and seeping into the well. 5. The well site need to rise sufficient to direct surface area runoff far from it. 6.
