Africa Needs Water
Testing your borehole water quality on a regular basis is an important part of maintaining a safe and reliable source. The test results allow you to properly address the specific problems of a water supply. This will help ensure that the water source is being properly protected from potential contamination, and that appropriate treatment is selected and operating properly.
It is important to test the suitability of your water quality for its intended use, whether it be livestock watering, chemical spraying, or drinking water. This will assist you in making informed decisions about your water and how you use it.
The quality of a water source may change over time, even suddenly. Changes can go unnoticed as the water may look, smell, and taste the same.
The only way to tell if your drinking water is safe is by having it tested at a certified laboratory. Harmful bacteria, parasites, and viruses are invisible to the naked eye, so water which looks and tastes good may not necessarily be safe to drink. These microbes can exist in surface and groundwater supplies, and can cause immediate sickness in humans if not properly treated.
Certain chemical contaminants that are sometimes found in a water source can cause long term health problems that take years to develop. Frequent water testing will identify unsafe water and ensure that the treatment system is treating the water to a satisfactory level.
Useful tests are available to help determine the health and safety of a water supply, and the performance of a water treatment system. There are different tests offer by the testing labs. Possible tests include
Include tests for coliform bacteria, nitrates, pH, sodium, chloride, fluoride, sulphate, iron, manganese, total dissolved solids, and hardness.
A common contaminant found mainly in groundwater. High nitrate concentrations can be particularly dangerous for babies under six months, since nitrate interferes with the ability of blood to carry oxygen.
Ions such as sodium, chloride, sulphate, iron, and manganese can impart objectionable taste or odor to water.
Excessive amounts of sulfate can have a laxative effect or cause gastrointestinal irritation.
Fluoride is an essential micro-nutrient, but excessive amounts can cause dental problems.
Represent the amount of inorganic substances (i.e. sodium, chloride, sulphate) that are dissolved in the water. High total dissolved solids (TDS) can reduce the palatability of water.
Other tests may be appropriate if a particular contaminant is suspected in the water. For instance, groundwater sources are sometimes tested for arsenic, selenium, and uranium. Both surface and groundwater sources may also be tested for pesticide contamination.
Borehole water should be tested a minimum of once per year. Drinking water supplies obtained from shallow wells and surface water sources should be tested more frequently (i.e. seasonally), as they are more susceptible to contamination.
It is important to test your drinking water at the tap and at the source. Testing both will help you determine if your treatment system is performing correctly, and if the quality of your source water has changed.
