What is Well Water Testing?

Well water testing involves collecting a water sample from the well and checking for contaminants and quality. They will only be tested for contaminants present in the well water at that specific location.

While pollutants vary depending on the water source and surrounding areas, the most commonly tested contaminants are bacteria, iron, calcium, and magnesium. If your well water is contaminated, it can cause infections like giardiasis, hepatitis A, and hepatitis B and lead to increased miscarriages, stillbirths, and congenital disabilities in babies. 

If your water is low on magnesium or has an excess of iron, it can result in muscle cramps, seizures, and even strokes or heart attacks.

Why Test Your Well Water?

Testing your water at home is essential for several reasons. First and foremost, you should ensure that your family drinks safe and clean water. Most contaminants in well water can be reduced or removed with the proper adjustments to your water treatment system.

It is also essential to test your well water because it will indicate how good your well water quality is. Poor quality well water can lead to multiple health and safety issues. 

How Often to Test Well Water?

The frequency of well water testing depends on a variety of factors, including the type of contaminant that is potentially present in your water, the age of your well, and the location of your property. 


In general, homeowners should test their well water at least once yearly for total coliform bacteria and nitrate. Still, more frequent testing may be necessary, depending on your situation. 

For example, lakes and rivers near or surrounding areas with higher agricultural and industrial activity levels may require more frequent testing.

What Should I Check For In Well Water?

Private wells typically include a variety of pollutants; here are the main components you should be testing for:

how to test your well water at home

1. Arsenic

Arsenic is an element that naturally occurs and is typically present in groundwater. It is linked to several health risks, such as cancer, heart disease, diabetes, and issues with cognitive development.

2. Nitrate

Nitrates, or nitrate, are common impurities typically found in groundwater. Newborns and young children are particularly vulnerable to the effects of nitrate contamination as it can damage the ability of red blood cells to transport oxygen throughout the body. 

 3. Coliform Bacteria

If your water has coliform bacteria, there may be potentially hazardous chemicals present, and it might not be safe to drink because coliform bacteria are frequently associated with animal excrement.

4. Sulfate

Another common pollutant found in wells is sulfate, which can react with air to create sulfur gas, which has the stench of rotting eggs. Excessive sulfate consumption might harm the digestive system.

5. Ions

Chloride, sodium, iron, and manganese can generally reveal ion contamination in wells. These are often decorative and can alter the flavor of water, but when consumed in large quantities, they may harm your health.

6. Fluoride

A high amount of fluoride in water can cause several health problems related to teeth and bones, especially in infants and young people.

7. Volatile Organic Compounds

Volatile organic compounds, often known as VOCs, can present several adverse health hazards that warrant concern, such as weaker immune system response, higher risk of cancer, and liver damage.

8. Lead

Lead is most frequently found in old municipal pipes, although it can also get into groundwater from industrial operations. Lead is a heavy metal, and there is no “safe” level for lead as it is a harmful accumulative toxin, meaning it can accumulate in the body over time.

9. Agricultural Chemicals

If your home is near a rural environmental farming area, pesticides, herbicides, and agricultural fertilizers can end up in your drinking water. You must eliminate these chemicals if found, as they can harm your overall health and cause problems even when consumed in small amounts.

How to Test Your Well Water at Home?

Have you ever wondered how to test your well water at home or the proper procedure? Then home test kits are the easy solution.

So let’s begin and find out how to test your well water at home using a test kit!

1. Find a Reputable Kit

Since kits typically lack the precision of laboratory testing, you should look for one from a quality brand. Choose kits that have been approved by the Environmental Protection Agency (EPA). These kits are available online and through home improvement retailers.

Nitrates and coliform bacteria are two common annual tests. However, you must also periodically test for inorganic substances, including arsenic, lead, copper, and silver. 

You should check for volatile organic compounds, pesticides, and herbicides every five years. Additionally, it will help if you examine the pH and hardness of your water.

2. Read the Instructions 

How you use a well water testing kit will vary depending on which one you get.

Therefore, you need to look at the kit instructions carefully to know what to do precisely. Not following the instructions may lead to inaccurate results.

For instance, you must utilize sterile containers and sterile settings while testing for coliform bacteria. You may have to let the faucet run for a while during some tests.

3. Collect the Samples

These kits typically come with three containers to collect the sample, a tube, and a bag to store the sample. The easiest sample collection method is using a bucket or pitcher.

If you are collecting water from a well, you will want to ensure it is clean and free of debris to prevent contamination. 

How to Collect Well Water For Testing?

Put a clean bucket or pitcher next to your well water source. Collect the water in the bucket or pitcher, then store it in a clean container. The container must be big enough to store the water you have collected. You must store and keep the sample clean as soon as you collect it. This will ensure the best possible results.

4. Place Test Strips From the Kit into Your Water Sample. 

Each pollutant you’re testing for requires you to dip the supplied strip. The strip should be allowed to process for the time specified on the package.

The strip will change color depending on whether the contaminant is present or not. Some strips display a range, while others indicate whether you have exceeded the limit for safe water consumption.

5. Using Liquid Reagent

Alternatively, some kits may require adding a few drops of liquid pH reagent into your water sample. The liquid pH reagent measures the water’s hydrogen ion concentration (ions), known as the water’s pH level.

In this case, collecting separate samples for testing each contaminant is necessary. Add the proper amount of liquid reagent, close the container, mix it, and assess the outcome.

How to Interpret Test Results?

Using a drinking water test kit at home makes it quite simple to interpret your test findings.

A typical test strip has four or five squares, each of which changes color to represent the quality of the water. Compare the strip’s color to the cards included in the package to determine which is correct.

You can determine the levels of contaminants in your water by comparing the color with the cards included in the kit. You can estimate how much of a pollutant is in your water by looking at how dark the color is.

Different Ways to Treat Contaminated Well Water

Once you have identified a potential source of contamination, you’ll need to take steps to treat it. The type of treatment you’ll need depends on the kind of contamination and the severity of the contamination.

You must chlorinate the water if the contamination is bacterial or viral. This kills bacteria and viruses. You can also disinfect the water using a UV light or ozone system.

If the contamination is organic, you’ll need to use a filtration system to remove the contaminants. 

One of the most popular and effective options to eliminate organic pollutants is reverse osmosis, which can remove up to 99% of the impurities. Additionally, activated carbon filters can remove chlorine, pesticides, and other organic compounds.

Finally, use a water softener or an ion exchange system if the contamination is from heavy metals. These systems use a resin to remove the heavy metals from the water.
