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.
Once we know the water is unsafe, all are problems are not solved.
Certain water pollutants could cause serious health conditions, many of which little is currently being done to stop. Can we determine if the supply of water is okay for usage?
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.
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.
Smell and taste can be connected because the nerves we use to detect them are also connected. Both smell and taste are sensations caused by nerves that spread from the brain to the upper soft palate. Because of this, a lot of the methods we use to test for taste apply to smell as well. That being said, there are some differences.
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 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.
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.
If these natural conditions are considered to not contribute to water discoloration, or otherwise recognized by not exist, industrial waster or other man made problems such as runoff pesticide is perhaps the culprit. Because of this, it's important to control the environment in which your water is produced. This can be difficult, but is ultimately worth it.
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.
