Free Water Test Reports
You can also check out free water test reports to check water quality. However, these tests will only inform you about the quality of water in your area, not the quality of water in your home.
Clearly Filtered is a service that provides general information about the water quality in your neighborhood. Input your Zip Code, see what contaminants are in the water, and find the best water filter.

What Do Water Tests Measure?
Depending on the type, most water tests give you detailed insights into the presence of contaminants in your water supply.
According to the Safe Drinking Water Act by the EPA, a contaminant is any biological, chemical, physical, or radioactive substance in water.
The EPA has detected over 90 contaminants in drinking water that fall into one of two categoriesβand each category depends on the health effects it may causeβacute or chronic effects.
Acute effects arenβt typically permanent effects because most of our bodies can fight off the contaminants, just like fighting off germs.
But these contaminants can be dangerous when consumed at high enough levels, especially in people with compromised immune systems.
Chronic effects are caused by contaminants such as radium and arsenic. Over extended periods, people who consume above the EPA safety standards are at risk of cancer, liver, kidney, or reproductive difficulties.
Common Drinking Water Contaminants
Arsenic
Arsenic naturally occurs in rock and is sometimes found as an industrial byproduct.
This natural component of the earthβs crust is present in high levels in the groundwater of most states in the U.S.
Testing for arsenic in tap water is important because it is a toxic chemical that can have serious health effects if consumed in high levels. Long-term exposure to high levels of arsenic can increase the risk of cancer and other diseases, such as skin disorders and neurological problems.
Additionally, it is essential to ensure that the water we drink is safe and free from harmful contaminants. Regular testing can help detect the presence of arsenic in the water supply and take steps to remove it or prevent exposure.
Bacteria
Youβve probably heard about the biggest E. coli outbreak in 1999 due to contaminated drinking water at a country fair.
This should be a good enough reason to test your water with the best home water testing kit and install a water filter in your home.
Testing for bacteria in tap water is important because it can indicate the presence of harmful microorganisms that can cause illness if consumed. Bacteria such as E. coli and coliform can indicate the presence of fecal contamination in the water supply, which can lead to serious health problems such as diarrhea, cramps, and other symptoms.
Additionally, other types of bacteria, such as Legionella pneumophila can cause Legionnaires’ disease, a severe lung infection. Regular testing can help detect the presence of bacteria in the water supply and take steps to remove or disinfect it to make it safe for consumption.
Calcium and Magnesium
Even though minerals like calcium, magnesium, and sodium do not have a direct impact in your health, their presence does cause hard water, which can cause several other issues like dry, itchy skin.
Testing for calcium in tap water is essential because it can indicate the water’s hardness, which measures the number of dissolved minerals, mainly calcium and magnesium, in the water. High calcium levels can cause scaling and build-up in pipes and appliances, reducing their efficiency and lifespan.
Additionally, hard water can also cause skin and hair dryness, and may leave a residue on dishes and clothes after washing. Regular testing for calcium levels in water can help identify if the water is hard and take steps to treat it if necessary, such as installing a water softener.
When Should You Test the Water in Your Home?
Itβs tricky to tell when to get your home water tested, but why wait until the last minute?
Iβve mentioned earlier that arsenic is naturally present in βHIGHβ levels in most U.S. states, so there are great chances that yours is no exception.
There are several common signs to determine when to get your water tested, most notably:
- Your family suffers from recurring gastrointestinal illnesses
- You live near agricultural areas
- Staining of plumbing and laundry
- Salty taste in your drinking water
- Living near gas stations
Final Thoughts
Conducting water tests regularly is important to check for potentially harmful contaminants such as bacteria and viruses and to ensure your familyβs safety.
Water test strips are an affordable way to test your water but only show the chemical concentration of a limited list of contaminants in your water.
Your water isnβt tested by experts so using water test strips is guesswork about the chemicals in your water.
Tap Score, however, gives you a detailed breakdown of the contaminants in your home water supply, rates your water, and even lets you know if your family is at risk.
It is recommended that you test your home water at least once a year for bacteria and every 3 β 5 years for other contaminants, for which Tap Score is a good deal.
For example, Tap Scoreβs actual city water test is $149, and the extended city water test is priced at $625, which equates to just $17 a month for a 3-year test.
