While some tend to believe that "water is water," subtle modifications within the composition of the water and water supply, namely water pollution can possess huge effects on the taste of the drinking water.
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.
Bad tastes are often encountered more with the source of raw water than from a residential tap. Earthy smells are a natural by-product of necessary biological cycles. Unwanted tastes are generally because of something being dissolved within the water, and these solvents may well be categorized into two main categories: organic and synthetic. By and large these compounds and chemicals are undesirable, but never ultimately harmful. They actually can generally be filtered out, but aren't in need of to be to become safe to drink, unless bacteria growth and turbidity is an issue, in this case at least some type of treatment method could be needed.
Certain water pollutants may cause serious health conditions, many of which little is being done to stop. How can we recognize if a source of water is decent enough for consumption?
When testing for bad tastes, it can also be more difficult to make use of an objective scale. If you think about it, it's hard to put a word to how something tastes. If someone asked you to describe the taste of your drinking water, what would you say? Determining what variation of water contaminants are found within the water is easy, but evaluating what exactly makes for good and terrible tasting water doesn't possess a strict water contamination definition. It's not terribly helpful to come up with scientific metrics of chemical concentrations, because the end user isn't going to be conducting these kinds of tests, and ultimately doesn't care about them. They can be helpful to establish a ballpark of how safe or unsafe a water source is, but ultimately you need to test with the same faculty the end user will test it, which is ultimately though nerves found in the mouth and tongue which can interact differently with different chemicals.
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 straight to odor. The "odor threshold" or the level of water contamination that is required to produce a noticeably unpleasant smell, is often a pain to pinpoint.
The entire trying out of water odor is performed utilizing a panel of participants. Demographic variety is vital in terms of selecting this panel is vital, and it is of course essential that the panel be sufficiently large, because olfactory abilities and preferences vary not only from person to person, but additionally in a single person from day to day, or maybe even an individual within the duration of just one day.
Color, when it's noticeable by the end user, has to be a truly horrific property of water, and will certainly entail some deeper unhealthy cause or trait of the water, but even if it didn't, it will signify a severe psychological problem for drinkers. Iron and manganese are typically 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?
So water is tested making use of a slew of metrics, precisely what does this mean for your health? Well for starters, test your water quality. A lot of people drink hard or contaminated water just 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 this basic metrics. It's the responsibility of everyone to check water quality and to make sure our communities have access to clean, safe water.
