Water hardness is a scientific term that refers to water whose composition constitutes a significant amount of dissolved magnesium and calcium minerals. Consumers of hard water derive benefits such as a dietary supplement of bicarbonate minerals of magnesium and calcium. The hardness of the water can either be permanent or temporary. The permanent hardness is one which the mineral content cannot be removed away through boiling, on the other hand, temporary hardness constitutes hardness as a result of dissolved bicarbonate minerals (magnesium and calcium) which can be reduced through lime softening or boiling of the water. Knowledge and skill in relation to the hardness of water are paramount. This enables one to mitigate upon on some of the risks and disadvantages of hard water. These include corrosion of pipes and fixtures, reduction of equipment life, inefficiencies of heaters, clogging of pipes etc. It, therefore, follows that water should be tested to ascertain the hardness in them. Some of the ways to test this water hardness include;

  1. Testing using a test kit

The method uses test kit stripe which when exposed on water changes color depending on the mineral content in the water. The test kit should be one that has stripped for calcium and magnesium. The procedural way involves insertion of the strip on water under room temperatures for few seconds, the strip is thereafter pulled off from water and color changes observed in comparison to the color chart with the test kit. This will enable one to determine the levels of the mineral substance of magnesium and calcium in the water.

  1. Testing of water

Under this method, the hardness of water is tested through a tasting of water. The excess minerals in the water supply (potentially calcium and magnesium) will make the water to have a metallic taste.

  1. Examination of water pipes and fixates

The method tests the hardness of water over a long period of time. In any case, the pipes and fixtures that would have significant levels of corrosion and build-ups demystify hard water. It, therefore, means minerals have been getting into the water thereby deducing that the water is hard.

  1. Testing by use of instrumental analysis

The test is done using an instrument referred to as colorimeter. The instrument passes light through the optical filter that transmits light of only one color to the detector where it’s measured. The difference in light color transmitted by a blank sample and one with a colored sample is the measurement of hardness and is directly proportional to the concentration of the water hardness.

  1. Smelling and observation

From this method, the hardness of the water is determined by the smell of the water. This method is unique. since it is used to determine the foul and beachy smell of water physically. Equally one can also determine the hardness by checking for a white scale which is usually left by hard water on sinks and bathtubs. In addition, the scum from water formed in hard water most at times clings to laundry making it rough with a sour odor. This, therefore, means smell and observation can be one of the easy ways to test water hardness.

In conclusion, understanding the cause of water hardness plays a great role in aiding to remove hard water effect. Testing of the hardness of water ranges informs, that is, from relatively cheaper and simple ways to a more complex one. Therefore, get a water softener system that is more accurate. However, irrespective of the method to be used, early testing always helps one reduce the negative effects of hard water.
