Fresh and potable water is, unfortunately, becoming an increasingly scarce resource. Usable groundwater isn’t just used for human consumption; it’s also an integral component in New Zealand’s farming industry, and is the cog that keeps its irrigation systems turning.
Many industries source their well water from underground aquifers, but the issue of actual water quality has only become the focus of study and debate in recent years. It doesn’t help that an even more recent study shows that most of the country’s groundwater has very dangerous amounts of nitrate present, which presents a very serious health hazard.
Water Well Drilling and Water Usability
The safety and usability of New Zealand’s groundwater ultimately comes from how the water well is constructed. Despite their rather simplistic appearance and function, water wells are very complex implements that become increasingly difficult to construct the deeper the well goes.
Another hindrance to the construction of water wells is the actual composition of the ground where the structure will be placed. Many water welling industries, such as Carlyle Drilling, note that the way the rock is formed determines how well the water will actually flow throughout the structure.
The materials present in the ground and soil is also another factor in the usability and safety of water sourced from wells. Water, for example, has an easier time going through sedimentary rocks such as Limestone compared to its metamorphic and igneous counterparts. It is, however, at greater risk of being contaminated by foreign bodies such as rocks and trace compounds due to the loose composition of the soil.
Safe Sourcing of Well Water
Ensuring the safety of well water and ground water should not just be restricted to rural areas and farming districts. In fact, the water’s safety and usability is actually more questionable the closer you are to large cities and developments. Here, the problem isn’t just the potential contaminants, but also the proliferation of bacteria and other microbes, as well as garbage and other waste products.
To ensure that the ground water is safe, comprehensive testing is necessary before and after the construction of the well water. Testing is required to check the composition of the soul, as well as to determine if there is an actual aquifer near the property.
Finally, testing should continue a few months after the construction of the well water to determine if the quality of the ground water itself changed as a side effect of the boring process and the construction of the underground structure.
While it may seem that these safety precautions only serve to make the process more complex, it’s necessary to ensure the safety and usability of the ground water being sourced and used on the daily.
