Water is an important substance for sustaining person life, that is why water quality testing and other water analysis procedures are so vitally important to our healthiness.
Unless you reside in the rural area and use well water (as well as then you may have your water tested for quality and safety by yourself), your municipal supply is often tested and analyzed to determine whether it's potable and whether any potentially hazardous pathogens or contaminants are present which may endanger the healthiness of those who depend on this source.
Testing for the purity or depending on the appliance at hand, the presence of a certain additive to ensure that it's within expected parameters is really a routine task in laboratories and quality assurance departments all over the world. Water analysis and quality testing are operations which are a part of the daily workflow not only in civil engineering such as system administration but in any research, clinical or production environment which relies on having water that is of a consistent quality.
One of the more common water testing applications is always to screen for the presence of microorganisms in supplies; the importance of which is instantly apparent should you'll just recall the fatal cases of cryptosporidium infections in Milwaukee within the 1990s. Many residents of the town were sickened and a few killed, largely because of a failure within the municipal quality testing procedures. Clearly, accurate water analysis can quite literally be a matter of life or death when it comes to drinking water supplies.
Testing is often performed along side and in large part to watch the effectiveness of reverse osmosis, electrodialysis and other water filtration systems intended to keep the purity and/or consistency of a supply. The range of tests performed as to water quality may include pH testing and testing for mineral content - tests that are particularly common in food and beverage production, where these quality factors can affect the taste and consistency of the finished product.
Water quality testing isn't only confined to large scale water systems like on the municipal level nor towards the laboratory environment. There are also all kinds of various water analysis instruments and testing devices which have been designed with home user in mind. While many of these don't provide the same kind of precision as those products manufactured for that scientific market, there is a growing interest on the a part of consumers in knowing exactly what is in the water they drink and these water testing devices for home are getting increasingly commonplace.
The quality from the water utilised in the home for drinking, watering plants and other common household uses matters, clearly. Quality testing is also mission critical within the laboratory, in the production of all manner of consumer goods and virtually wherever that water is used, making water analysis something that is as vital as water itself; essential to our very survival as a species also to the upkeep of our healthiness.
