What are the disadvantages of shallow wells?
they easily spread diseases
they are shallow in nature
How do I know if a shallow well that has not been used for 20 or so years is still good and How do I set up a shallow well pump to it?
If the pipe is still in the ground, drop a weight on a string down it and see how much if any water is in the bottom of the pipe. Shallow wells can come and go depending on location, the source of the water and the weather. If there is still water in it, you hook a pump up to the pipe, prime it and start pumping.
Depending on location, water underground can be is a layer that can be tapped anywhere in that area. Other places, it is in a stream, much as it is above ground. You dig a hole and go a little past the level of the water, install a casing or pipe for collection and a smaller pipe inside of it to pump out the water. Shallow wells have the pump above ground and deep wells have…
One of the disadvantages of the Tigris-Euphrates river was its limited use for transportation. The northern stretches were shallow and rocky. The prevailing wind also blew in the same direction as the flow of the river. This meant you could not sail your boat against the current. Boats got upstream by being towed by teams of slaves trudging along the banks.
Answer:Artision wells Answer: No water source is 100% certain to be pure. Surface water from run-of would likely be the most chancy. shallow groundwater next. At the other end of the scale deep groundwater (artesian wells etc.) and glacier derived water (because it represents water from rain/snow that fell several hundred years ago) is probably safest.

Natural oil seeps were common in the Middle East, and was used as a part of construction as far back as 4,000 years ago. It may have been used for medicine and lighting. Also, oil was "discovered" early on in the US when digging shallow water wells, but it was considered a contaminant instead of a useful fuel. The first wells drilled to produce oil to be used as fuel occurred in Pennsylvania, in 1859…
Fossil fuels is extracted from the earth in a number of ways, depending on which type of fossil fuel is being extracted. Natural gas and oil are produced by drilling wells. These wells may flow naturally, or require artificial lift. See related link. Coal is extracted from mines. If the coal is shallow, open pit mining may be used. However, more recent discoveries are deep, requiring underground mining. See related link.
