Drinking water is defined as water that does not pose health concerns to users. A huge percentage of people drink contaminated water resulting in many illnesses some of which are rapidly fatal. These diseases can be rapidly spread especially among communities that live close together. Eradicating related diseases is one of the major public health goals in the developing world. Drinking water testing is one of the many ways towards attaining this aim.
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.
There are a number of other observations that can be used to decide whether there is a need to take samples. For instance, if there is an increase in the occurrence of unwanted environmental events such as increased incidence of diarrheal diseases, destruction of sewage drainage systems within the vicinity, increased levels of wear and tear and increased hardness among others. If soap starts to lose its ability to lather easily, testing should also be considered.
Babies are highly susceptible to nitrate poisoning. Exposure to high concentrations of nitrates may result in blue baby syndrome (methemoglobinemia) where oxygen levels in the body are insufficient to meet the body demands. Immediate medical attention is crucial for the survival of affected babies.
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.
Once the samples have been adequately tested and the contaminants identified, one of the steps that can be undertaken is the installation of filter systems to remove impurities. The main downside is that important components such as fluoride may be filtered out. Fluoride is an element that helps strengthen tooth enamel and prevents decay.
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.
