Human Impact on Ground Water

KONICA MINOLTA DIGITAL CAMERAHuman activities or interactions with the environment can be clearly identified as having a direct impact on the world’s ground water supply. Human activities have affected the distribution, quantity and quality of water resources from continent to continent. The extent of impact differs from activity to activity as well as from the initial environmental makeup. Some of the activity that impacted water was simply due to lack of appropriate resources or knowledge. For example, for centuries humans have unknowingly contaminated ground water and drinking water sources with the inappropriate dumping of raw sewage. Let us look more closely at two human activities that have showed significant impact to our ground water sources.

Industrial Development – Industrial Revolution

Perhaps one of the first activities that would come to anyone’s mind when considering environmental impact would be that of industrial development. From the beginning of the Industrial Revolution in Europe to today’s continued manufacturing, impact has been notable. Coal use in the industries resulted in smog and soot, killing thousands of people. Factories began releasing pollutants directly into rivers and streams with no thought or regard for how it would impacted the ground water in the area. Another by-product – acid rain, first discovered in the 1850s, began to release sulfur and nitrogen into the atmosphere, impacting plants, fish, soil, forests, etc. There can be no doubt that the Industrial Revolution introduced our society to amazing technological advances, but it also introduced new sources of air and water pollution, some that did not become obvious until the 20th century. In addition to introducing new pollutants to the environment, water levels were also impacted as the need to use water in the factories increased. Water sources were tapped into without any regard for overuse.

Agriculture

When most people think of agricultural practices around the world, they might not immediately connect it to an impact on ground water, however agriculture has been the cause of significant modifications of landscapes throughout the world, have changed the natural flow of water, have polluted standing water sources and have depleted water in many areas. Working the land through clearing, planting and tilling affected ground water immeasurably. The loss of water through soil erosion was one of the biggest changes. Two areas that have had the greatest impact to the quality and quantity of ground water was the use of irrigation practices and the application of chemicals to croplands.

As human impact continues to affect ground water, the need for technology to guide us in finding adequate water sources will continue to rise and the need for organizations that one can trust to guide our searches will increase.

Water Well Drilling Throughout the World

Water well drilling has been around for centuries. Although many people know what a well is, many less have actually seen one. In a world of urban sprawl, it may seem strange to consider water wells when you live in the city and simply have to turn on a tap. There are many types of water wells, however, depending on which continent you are looking at.

Australian Aboriginals used to use their hands to dig down through the desert sand until they reached mud, and eventually clear water. In order to preserve these spots of water, they would cover them up with wild grasses to protect them from the sun, bugs and dirt. In India, elaborate stepwells, which are literally wells that you must descend into via steps to fetch water, were also used to escape heat and add architectural beauty. Middle Eastern and Asian countries had more sophisticated water well drilling techniques that involved a series of wells joined by underwater canals. These were known as Qanats.

Beginning in the Iron Age, wells became very common features in civilized areas, and at this time, wells were typically lined with wood or wicker. Interestingly, the world’s oldest known wells were found in Cyprus and date back to 7500 BCE. Until modern wells, wells were dug by hand and required the water to be brought up from a varying degree of depths, most often using a bucket and a rope. As technology advanced, people discovered how to use gravity to bring water to the surface, which is how Qanats functioned. With modern water well drilling, we now have the benefit of technology that allows for pumps, and mechanical drilling that permits us to reach water aquifers at great depths.

Hand dug wells are still created today in places all around the world. They are cheap and effective and can be made by anyone, if the right spot is chosen. Driven water wells are also still created because of their cost-effectiveness. A driven well is created by hammering a pipe into the ground with a tripod and a driver. Importantly, no matter what sort of well is dug, it can always be cleaned up and encased to ensure it remains usable for lengthy periods of time.

Hand dug wells, for instance, can actually be quite deep and impressive. Although it is common to see a wallow type of ditch as the result of hand digging, the resulting well is largely dependent on the earth you are digging in. Sand, for example, is difficult to dig in and could require bracing to achieve any great depth, but dirt and clay would be much more manageable.

Water well drilling has been a necessity for people to survive, especially for those not located near convenient water sources, and thus its been a technology that despite rudimentary roots, has advanced incredibly throughout the centuries.

The history of water well drilling world-wide is as interesting as it is diverse. Each continent found ways around the unique challenges posed by their environment, and overcame them.

Water Well Drilling technology used by American Water Surveyors Saves Clients Money

American Water Surveyors, a water finding company, uses innovative technologies such as seismo-electric water locating to efficiently locate fresh groundwater. These methods are beneficial to clients as they are less costly and provide depth and water volume data.

American Water Surveyors uses innovative technology for finding water. Finding water through water well drilling is often quite difficult and it does not always pay off.  Since you have to pay for the drilling whether or not water is found, having to pay for a hole on your property that yields no water is as frustrating as it is expensive. It’s no wonder so many residential and commercial clients trust our water-finding technology.  Not only can we help find water and tell the drillers where to drill, we can estimate the flow and yield.  No more dry wells!

Finding Water through Well Drilling

Various drilling methods have been developed due to geologic conditions, ranging from hard rock to alluvial sand and gravel. Certain drilling methods are implemented more often than others depending on the local aquifers. Each drilling method has advantages and disadvantages. Often, holes can be drilled without the use of any drilling mud, as a result minimizing the well development time and site clean up costs. Pumping tests can be carried out in zones at several depth during the drilling process to collect groundwater samples and examine the quality of all aquifers that may be present at a particular location.

Seismo-electric Method

This method is efficient for drilling fresh groundwater. The most prominent benefit of this method is measuring the streaming potential of the well water. Seismo-electrics primarily looks at the fluids in rocks and soils. Many other technologies, like Nuclear Magnetic Resonance, are also used for water well drilling, but can be much more costly and involve limitations such as the inability to give unambiguous depth information as compared with seismo-electrics. While the seismic wave stresses earth materials, several phenomenon occur: the resistivity of the earth materials modulated by the seismic wave, electro-kinetic affects analogue to streaming potential are created by the seismic waves, seismic waves create piezoelectric effects, and high audio and radio frequency impulse responses are generated in sulfide minerals.

GF 3500

The GF 3500 and seismic methods are used together in order to generate and collect seismo-electric signals. The source is used to create a sound wave which, when moved through aquifers, moves the water relative to the rock formation. The water ions that are dragged away from their partners bind to the rock; an electrical dipole is set up that flickers at seismic frequencies. The electromagnetic disturbances are created where changes in the rock occur and ions travel to the surface. This method provides depth and thickness data through reflection seismology. The form each signal gives off provides information about the depth, thickness, and quality of the aquifer. This is used to estimate the water yield from a borehole drilled at the survey site.
