Not all water is created equal. A little contamination can wildly effect how safe water is to drink, and many people fail to realize this. It's important to protect against these possible pollutants, but before any steps such as filtration or softening can be taken, we need to know that the water is unsafe.
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.
Testing water is no simple business. A lot of the things we can test for don't directly lead to it being dangerous or safe, so it's only useful to test water if we can draw conclusions from it. Many of the things we can directly test, such as temperature, or chemical makeup, only give us hints as to how bad or good it will serve as drinking water. Color, taste, odor, and particles all some of the things we can test in a lab, and they let us know if the water is safe to drink, or worth treating further so that it will ultimately be fit for consumption. We can look at these characteristics and tests to see how we ascertain water quality.
Bad tastes are often encountered more for the source of raw water than out of a residential tap. Earthy smells certainly are a natural by-product of necessary biological cycles. Unwanted tastes are regularly a product of something being dissolved in the water, and these solvents may well be categorized into two main categories: organic and synthetic. Any time a solvent is organic naturally it originated from the very same natural processes that produced the water-in short, it came from nature. Largely these compounds and chemicals are undesirable, but not ultimately harmful. They can generally be filtered out, but don't need to be to actually be safe to drink, unless bacteria development and turbidity is an issue, in this case some kind of treatment may very well be vital.
It can be hard to test tastes on an objective scale. It's easy to check out what the chemical composition of a sample is, but it's hard to match that to "good tasting" or "bad tasting." The best way to test taste is to figure out: what will the consumer think. If a taste isn't offensive to an actual person, it's good to go.
It's challenging to be aware of exactly what compositions or mixtures of chemicals can have negative effects on the subjective taste of the water. 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." Those may sound silly, but it's hard to stick something as ubiquitous as taste into a single word. These subjective assessments give researches a quality place to begin to base further investigation along side.
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.
Of course, just like taste, it is hard to pin down smell with quantitative data. It is much easier to used test subjects to help determine an "odor threshold", or the point at which smell becomes noticeable and unpleasant.
The entire trying out of water odor is completed with the use of a panel of participants. Demographic variety is useful when it comes to selecting this panel is pivotal, and it is also essential that the panel be sufficiently large, because olfactory abilities and preferences vary not only from individual to individual, but as well in a single person from day to day, or perhaps even one individual in the duration of only one day.
If the consumer turns on the tap and gets a shower of unclear liquid, regardless of the safety or contamination of the water, they're going to be quite uncomfortable. Discoloration in water can suggest seriously deeper issues, but even if it didn't, it would still pose a problem for drinkers because of the psychological ramifications of drinking cloudy water. Coloration can come from a number of sources such as algae, runoff pesticide, or silt.
These conditions do not happen to be outright poisonous, but could well be unhealthy when it comes to the drinker, and would 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 known to not exist, industrial waster or any other man made problems namely runoff pesticide is perhaps 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 using a slew of metrics, simply what does this mean for you? Well for starters, test your water quality. You're whole city could be ingesting dangerous or harmful chemicals because not a single person has taken the an opportunity to evaluate the water on these basic metrics. It's your responsibility to your community to make sure the water supply is kept clean and safe to drink.
