Even though some are predisposed to believe that "water is water," subtle changes in the whole makeup of a water source, such as water pollution can really change the way people see their water. Just a little contamination can jeopardize the health and well being of people.
But it becomes worse:
Water has numerous different qualities and properties, and most of these don't directly effect how well or poor it'd serve as drinking water, though many of those can. People want water contamination information regarding the water they're drinking, so several methods have been developed to check water condition. Let's examine those properties individually.
Water has many different qualities and properties, and many of those don't directly effect how well or poor it'd function as drinking water, but many of them can. Of them properties, color, taste, odor, and sediment are all important things that could be measured and might give insight into whether or not that water main would be suitable for consumption, or perhaps even for filtration. People want water contamination information regarding the fluids they're drinking, so several methods have already been developed to check water conditions. Let's examine those properties individually.
When water tastes bad, you usually have the origin of the water to blame. Generally speaking, bad tastes make their way into the water where they first originate, such as a spring or reservoir. These tastes are not usually picked up in the process of bring the water to your tap. Organic tastes are generally the product of organic processes, and while these tastes wont seriously hurt you, and aren't a real threat to your health, they can be seriously unpleasant, and they often mean there are deeper issues with the water supply. There is a chance these tastes could come from bacteria, which would mean the water would have to be sanitized before it became fit for consumption.
When testing for bad tastes, it can also be hard to utilize an objective scale. Determining what kind of water contaminants there are in the water is easy, but discovering what makes for good and poor tasting water doesn't have a very strict water contamination definition. Ultimately it is though nerves found in the mouth and tongue which can interact differently with different chemicals that water is really "tasted".
It's problematic to be aware of exactly what compositions or combos of chemicals will have unintended effects upon the subjective taste of the water, so human testers are usually more useful than chemical lab specs. Testers often use qualitative metrics, or water contamination symptoms to explain the water they taste which can include "swampy, grassy, medicinal, septic, phenolic, musty, fishy, and sweet." These subjective assessments give researches a reliable start line to base further investigation from, and help them know if water is filtered or softened enough to be drinkable by the average citizen.
Odor and taste are closely related, as they are related in the forms of sensory inputs they rely on in the human body; a lot of our sense of taste is reliant upon sensory input from nerves that encounter smell.
Unlike taste, it has been generally accepted that many smells found within water are caused by the presence of organic water contaminants, or microorganisms and the processes they execute while decomposing green matter. There are many cases in which industrial or synthetic chemicals can cause distinct odors in water, but these usually are derived from chemical processes that produce organic water contamination being a byproduct.
Obviously, the ultimate user experiences odor using their nose, so not objective metrics can possibly be applied right to odor. Researchers can normally identify the different kinds of chemicals and compounds that produce unpleasant odors, yet the "odor threshold" or even the grade of water contamination that's required to supply a noticeably unpleasant smell, will often be a challenge to pinpoint.
It's important to test water for smell with a large group of testers. From a statistical point of view, a small sample of smell testers wont produce a very reliable result. Peoples' smell preferences and sensibilities vary from day to day an person to person, so it is also helpful to have testers test the water several times on different days. This can take out a lot of unwanted confounding variation.
Color, when it's noticeable by the end user, could be a truly horrific property of water, entails some deeper unhealthy cause or trait of a given water, and even if it didn't, it'd signify a serious psychological problem for drinkers. Iron and manganese are generally the reason for most discolorations, but humus, plankton, algae, and weeds might also cause serious discoloration.
These conditions commonly are not outright poisonous, but just might be unhealthy when it comes to the drinker, and shall certainly manifest their unique presence through unacceptable odor, taste, or acidity. If these natural conditions are known to not add to water discoloration, or otherwise considered to not exist, industrial waster or any other man made problems such as runoff pesticide may very well be the culprit.
Color is most often measured as "true color" (in other words each of the insoluble bits of the water-the floaters-have been removed), and "apparent color," or the color the end user would see if they needed to access the water source without first running it through a sediment filter. The best sediment filters (if they're doing their job) clean, purify, and remove color from the water run through them. These colors and their corresponding water contamination effects are tested against several predetermined pigment values, much of which are declared as okay for consumption, and many of which are not.
So what?
We've just examined some of the biggest factors on water cleanliness. So water is tested utilizing a slew of metrics, exactly what does this mean for you? Well for starters, test your water quality. A lot of people drink hard or contaminated water entirely because they don't know they're doing it. You're whole city just might be ingesting dangerous or harmful chemicals because no person has pushed the time to evaluate the water upon the basic metrics.
