Why You Should Check the Drinking Water

Although it is known as drinking water, the water running from our taps is far from being safe for drinking particularly due to the sterilizing substances the municipality uses. Moreover, many residues get into the water before it reaches the pipes in your house, this being the reason why it is essential to take measures in verifying the safety of the water you drink. From chlorine that alters the taste and odor of the water to dangerous heavy metals like lead and mercury to harmful pesticides and bacteria, the water that you use on a daily basis is contaminated with impurities that can trigger severe health problems. Water testing kits are a simple and affordable way of checking the quality level of the water at home, any time you want to be certain that you are using pure and safe water.

The reason why it is important for you to check the water that you drink should be obvious by now, the many contaminants that lurk in it presenting a great danger to your health. Also, without checking the water, you won’t know exactly what contaminants you have to get rid of either. In case you plan on investing in a water filtration system, it is crucial to know what are the impurities that you want it to eliminate from the water, this way making sure that your money will be spent on a model that is actually going to do a great job.

This way, you know what type of contaminants you are confronted with, being able to more easily remove them with the help of an appropriate water filtration system.

When it comes to how they work, it is all pretty easy to understand. What you generally have to do with them is to drop a solution in the water, or put the water in a special capsule. The water will then change colors according to the types of contaminants that lurk in it. To determine exactly what are the contaminants that are found in the water, you will use the kit to compare colors.

They check for a variety of conditions, so it is essential for you to pay attention when purchasing them, ensuring that you will invest in a model that checks for as many contaminants as possible. All in all, they are not only easy to use and effective, but they are essential to your health and well-being, so you cannot afford to skip buying them.

Frequently Asked Questions

1Is there any advantage to checking the water myself as opposed to taking it to a professional lab?
Regardless of the method you go with, the outcome is the same – you will find out what contaminants lurk in your drinking water and you will learn other interesting facts about its quality. However, checking the water’s quality at home is the superior choice to go with as you receive the result on the spot. If you take a water sample to a lab, you have to wait for days, even weeks for the result to come.

2Does an unbalanced water pH affect my health in any manner?
By drinking water with an unbalanced pH level, you actually cause a shift in the pH level of your body. If the pH level is too low, your body becomes too acidic. In case the pH level is too high, your body becomes too alkaline.

3What are the common water contaminants the tests check for?
Generally, they check for contaminants like lead, chlorine, copper, iron, pesticides, herbicides, nitrates, and bacteria. Another common trait is the fact that they check alkalinity and pH levels. However, this is not set in stone as these products differ from each other. Check their spec sheets to find out exactly how they can aid you.
