Drinking water should always be safe for human consumption. A large percentage of the world population drink water that is not safe leading to widespread diseases and death. Minimising the related diseases is one of the most important public health goals in many countries. Drinking water testing is just one of the ways to achieve this goal.
Testing needs to be done often to make sure that what you are drinking is safe. A variety of contaminants may be found in samples based on the environment. Examples include iron, manganese, lead, radon and sulphate. Perhaps the most troublesome problem is the presence of bacterial organisms. Organisms are difficult to visualise and the samples taken may actually appear to be of good quality just by looking. Microorganisms should be tested in stored sources at least once a year.
Certain circumstances may require testing more than once a year. For instance, alteration in odour, taste or color may require regular testing of sulphate, manganese and iron concentration levels. Mysterious diseases arising in the family or neighbours may also be linked to source contaminatio. If one is pregnant, it is necessary to test samples before the baby is born, after birth and during the first six months of life.
The occurrence of unwanted events such as sewage drainage destruction or blockage should raise the suspicion of contamination. One should also get concerned when there is a certain outbreak of diarrhea diseases. When water equipment gets worn out at a faster rate than usual, chances are high that this is linked to corrosion, hardness and pH changes. Inability of soaps to lather easily should also be considered.
The most vulnerable group of persons with regard to diseases are children less than five years and particularly the infants. Overexposure to nitrates to these group leads to nitrate poisoning. It subsequently results in a condition known as the blue baby syndrome in which the levels of oxygen are too low to meet the metabolic requirements. When identified, this condition should be treated as a medical emergency.
The samples used for this process are taken in different ways. The first sample is what comes out of the tap first once it is turned on in the morning. Another sample should be taken after the stream runs for some time. Samples can be collected at different points in the piping system when contamination has occurred in more than one section. Suggested points include inlet and outlet of a filtering device or before and after entry in storage tank. An allowance of 12 hours should be given when collecting the sample from a system suspected of corrosion.
Installing filters in the home can help get rid of some troublesome contaminants such as lead. This should be done after the samples have been tested to know exactly what impurities are to be removed. There are particular types of filters: distillation systems and reverse osmosis systems filter out fluoride. In such cases, measures have to be taken to ensure fluoride is obtained by other means to avoid tooth decay. Also, change the filters often to prevent accumulation of contaminants.
Even after the safety threshold has been reached, it is important to ensure that there is proper storage. This will help reduce the chances of contamination and diseases later on. While in storage, drinking water testing should be done regularly to make sure that the status has not changed.
