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.
Regular sampling should be done to ensure that purity is maintained and safety is guaranteed. As much as this is the responsibility of the public health department, you should not take any chances. Instead you should take the initiative to collect samples and ensure that indeed they are of good quality. Depending on the location of the source, various substances may be detected. These include radon, sulphate, iron, manganese, pesticides and so forth. The most common quality challenge is bacteria, which has to be tested at least once a year.
There are situations that may require testing to be done more frequently within a year. If there are changes in colour, smell, taste and clarity one should suspect high levels of contaminants such as iron, sulphate and manganese. At the same time, whenever unexplained illnesses are noted among people who drink from the same source. Home testing should be done if a member of the household is pregnant.
Specific conditions call for specific tests to be carried out. For example, there should be tests for the presence of coliform bacteria when users develop recurrent gastrointestinal illness. Failure of soaps to lather easily during washing may require a test for hardness. Rapid wear of pipping equipment is a sign that samples need to be tested for PH, alkalinity, corrosion and hardness.
Infants are vulnerable to nitrate and overexposure to the same can lead to nitrate poisoning. This results in a blood disorder termed blue baby syndrome which is characterised by very low levels of oxygen which cannot meet the requirements. It should be treated as a medical emergency in the event of exposure and symptom presentation.
Either a simple flush in the morning or after the tap has run for a while can be used as a sample. Sampling from different points may be needed in case contamination is suspected to be in the plumbing system. This can be before and after water enters a storage container or at the inlet and outlet of a filter. Testing for corrosion in the plumbing system warrants collection of the sample after twelve hours of settling.
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.
Water is essential for the survival of humans and other living organisms. It makes up over 70% of the human body weight. Sampling is the most important part of drinking water testing. Therefore, instructions should be carefully followed to obtain accurate results.
