Why You Should Test 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 tests kits are a simple and affordable way of testing 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 test 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 testing 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.

How Water Quality Testing Kits Work

These kits are designed to be extremely user-friendly, thus being a wonderful option to go with for all people. They are designed to allow you, as a user, to test the quality of the water that comes out of your tap and that you use to drink, cook, and bathe with. 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 these kits 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 home testing kit to compare colors.

These kits test 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 tests 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 testing the water myself as opposed to taking it to a professional lab for testing?
Regardless of the testing 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, testing 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 that these tests check for?
Generally, home water testing kits check for contaminants like lead, chlorine, copper, iron, pesticides, herbicides, nitrates, and bacteria. Another common trait is the fact that they test 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.
