A reliable water test kit can provide you with the necessary information to make informed decisions about your water treatment options. By regularly using a water test kit, you can detect harmful substances early and take appropriate measures to ensure your water is safe to drink.
Whether you are concerned about bacteria, lead, or other contaminants, a comprehensive water testing kit can help you maintain a healthy drinking water supply.
Types of Well Water Contaminants
Well water can be affected by a wide range of contaminants that may compromise your water supply and your family’s health. Common sources of contamination include bacteria, such as coliform bacteria and E. coli, which can signal the presence of other harmful pathogens. Viruses and parasites may also find their way into well water, especially after heavy rainfall or flooding.
Chemical contaminants are another concern. Nitrates from fertilizers, lead from old plumbing, and volatile organic compounds from industrial or agricultural runoff can all seep into groundwater. In some regions, well water may even contain radioactive particles or heavy metals like arsenic, which pose serious long-term health risks.
Because these contaminants are often invisible and tasteless, regular testing with a comprehensive water test kit is essential. A reliable test kit can help you detect bacteria, chemicals, and other pollutants, giving you the information you need to take action and ensure your well water is safe for drinking. By using a water test kit, you can stay ahead of potential problems and protect your water supply from a variety of threats.
Sources of Bacterial Infections of Drinking Water
Human, as well as rodent waste products, can be a principal source of bacterial contamination in well water. These sources of bacterial contamination consist of run-off out of yards, feedlots, pastures, canine runs, and other farm land areas where animal wastes are deposited. Bugs, rats or rodents, or wildlife entering the well can also be sources of contaminants.
Some other sources include things like leaks coming from septic tanks as well as sewage treatment services.
Bacteria from these sources can enter home water wells if these wells are: 1) open on the surface, 2) don’t have water-tight casings or caps, 3) do not have a seal of grout in the space (the space between the wall of the well and the outside of the well casing).
Generally, you need to test for three categories of coliform bacteria: total coliform, fecal coliform, and E. coli. Finding total coliform alone doesn’t necessarily mean the water source is contaminated. Comprehensive testing for various contaminants, including lead, is crucial to ensure water safety and make informed health and water treatment decisions.
Coliform Bacteria
Coliform bacteria live in soil, on plants and flowers, and in surface water. They are also found in the intestines of warm-blooded animals and their feces and are known as E. coli.
Several strains of coliform bacteria can easily survive for long periods in soil and water. Insects can also transport bacteria into well casings. Coliform bacteria are the most common contaminants seen in private water systems. Your well should be tested at least once a year for bacteria. Achieving an accurate reading is crucial to ensure the safety and quality of your water.
Whenever total coliform is detected, additional tests are performed to verify the presence or absence of fecal or E. coli bacteria.
Contamination Risk After Well Servicing
Wells that have recently been worked on, such as those that have been drilled or repaired, can become contaminated by the work itself. The construction process can introduce bacteria, sediment, and other contaminants into the well. It is essential to test your well water after any work has been done to ensure that it is safe to drink.
A comprehensive water testing kit can help you identify potential contaminants and provide you with the necessary information to take corrective action. After well maintenance, you can use a water testing kit to detect any new contaminants introduced during the work and take steps to ensure your water remains safe and clean. Regular testing helps identify water issues that may arise after servicing, such as bacteria, pesticides, or other harmful substances, ensuring ongoing water quality and safety.
Two Main Entry Points for Coliform Bacteria in Wells
One is the original drilling and installation of the pump, and the other is when the well or pump is being repaired. Original drilling processes include the activities related to the original construction of the well, including the original pump installation.
This represents the well's first and usually most severe exposure to bacterial contamination. Because there are so many different ways to introduce bacteria into the system, the original well construction can often be the cause of an ongoing bacterial problem that can go on for many years.
All water used in the drilling process must be chlorinated-treated or, at the very least, free from bacteria or viruses. Thoroughly chlorinate all water used during drilling and before it is introduced into the well.
Do not assume that the water used for drilling obtained from a neighboring well is free from bacteria. Add chlorine of not less than 50 PPM (mg/L) to any water entering the well, no matter where the water came from. Testing for lead and bacteria requires careful attention and concentration to ensure accurate results and reassure users about the safety of their drinking water.
Other Sources of Contamination
Equipment and tools lying on the ground or the bed of a service truck also represent excellent paths for bacterial or viral contamination. This equipment should be kept as dry and clean as possible, covered until needed, and washed down with a chlorinated solution before being placed in the well.
Flood water can contaminate your well water with bacteria, parasites, and other pollutants. Other sources, such as spring water, can also be vulnerable to contamination and should be tested regularly. Do not drink water from your well if it has been covered by floodwater. If your well is older than 10 years and is less than 50 feet deep, it may be impacted by contamination, even if the actual well head is not covered. Shallow wells and/or older wells with bad well seals can be under the influence of surface water, even if the surface water is not directly covering the top of the well. It is crucial to regularly test private wells for various contaminants, including bacteria and nitrates, to ensure safe drinking water. Testing can also help determine if a water softener is functioning properly and addressing hard water issues.
Before disinfecting your well, check its condition. Make sure there is no exposed or damaged wiring. This is a Shock Hazard! Contact a well professional before the disinfection process if you have any doubts about the integrity or condition of your well. Do not attempt to do this yourself until your well has been inspected.
Drinking Water Quality
Your drinking water quality directly impacts your family’s health. Well water can vary based on local geology, land use, and environmental factors. Hardness, pH imbalances, and dissolved solids can affect both taste and safety.
A water test kit makes it easy to check for bacteria, lead, nitrates, and other contaminants. Regular testing helps ensure your water meets EPA standards and alerts you to changes before they become serious.
By testing regularly, you take a proactive step toward keeping your water clean, safe, and reliable.
City Water vs Well Water
City water and well water differ significantly in treatment and monitoring. Municipal facilities process and regularly test city water, often adding chlorine or fluoride to meet public health standards.
In contrast, well water comes directly from underground sources, and the homeowner is responsible for its upkeep. Nearby agriculture, septic systems, and industrial runoff can easily contaminate it. Because no agency regulates well water, homeowners must test it regularly to ensure safety.
Even if you use city water, a DIY test kit can help detect issues from aging pipes or local infrastructure. No matter the source, regular testing empowers you to spot problems early and choose the right treatment for safe, clean water.
Choosing the Right DIY Kit
Choosing the right DIY water test kit can be overwhelming because there are many options. When choosing a kit, consider the contaminants tested, ease of use, and result accuracy—some DIY kits only detect lead, while others test more but may be harder to interpret or less reliable than lab results. Look for kits with clear instructions, patented technologies, and certified lab testing.
Also, think about the cost, including shipping, and whether the kit has a good housekeeping seal. Some kits include shipping in the price, making them more affordable. A reliable DIY kit gives you a clear picture of your water quality and helps identify health risks. Some kits test for a wide range of contaminants to provide a complete picture of your water's safety.
By choosing a high-quality test kit, you ensure accurate and reliable results. This gives you peace of mind about the safety of your drinking water.

Coliform Testing, How It Works
Fill the bottle with untreated well water.
The media will turn blue-green if coliform bacteria are present, or remain clear-yellow if they are absent.
For 24-hour results for coliform bacteria, heat the sample to 95 °C for 24 hours. If kept at 77°F, the test will take 48 hours.
Heating the sample is not required and does not affect the accuracy, only the timing of the test.
You don’t need UV light to perform a coliform bacteria test. However, if the test detects coliform bacteria, you should disinfect the water—or avoid consuming it—whether or not E. coli is present.
E. coli Testing Is Easy
To confirm E. coli growth, simply shine a UV light on the sample. Blue fluorescence indicates the presence of E. coli. You can use a UV light tool (select “UV Light” from the button menu) to verify your results.
