How to Test Your Water Quality at Home Without a Kit

Whether you’ve recently moved into a new home or taken a new interest in your home drinking water quality, you may be wondering how to determine the purity and safety of your water supply. 

While various at-home packages are available for assessing the water in your home, these packages can be expensive and slow to ship. In this article, we’ll explore how to test water quality at home without a kit to assess for bacteria, lead, nitrates, nitrites, and chlorine.

With the help of four simple at-home tests, you can establish preliminary parameters about your home’s water quality. This information can help you establish a purification plan and harness water treatment technology that addresses the specific water quality issues in your home. 

#1 Assess Color, Taste, and Odor Test

How satisfied are you with your water? Three crucial, qualitative characteristics of your home water supply can indicate the presence of hard water:

  • Odor
  • Color
  • Taste

While it can be difficult to pinpoint the precise causes of odor, color, or taste abnormalities, identifying issues is the first step in the mitigation process. 

If you’re not sure how these qualitative factors impact your current water supply, evaluate your tap water against one of the purest water products on the market—bottled, distilled water. 

While even the most highly distilled water products aren’t 100% H2O, distilled water can serve as a neutral comparison point for your household water quality.

To evaluate the odor, color, and taste of your tap water, compare each metric to those you observe in distilled water samples. If your at-home drinking water has a funky odor, color, or taste compared to the distilled control, your home drinking water supply might be contaminated.

#2 Use a Water Hardness Test

Water hardness describes the total concentration of dissolved calcium and magnesium solids in a water sample.1 

If your home has hard water, you may experience one or more of the following everyday impacts:

  • Chalky stains on dishes, plumbing fixtures, and countertops
  • Soap scum residue in areas where you use soap (e.g., showers and sinks)
  • Low water pressure 
  • A chalky dry feeling when you wash your hands or body, or when you do the dishes
  • Low soap sudsing

One sure-fire way to test your home water hardness without a testing kit is to do the following:

  • Dispense tap water into a ladle or large spoon
  • Lay the spoonful of water on a countertop, and don’t disturb it for 24 to 48 hours
  • Once the water has evaporated, look for white spots or sticky residue on the spoon

If you observe lingering residue after the water has evaporated, you may have hard water issues at home. Filtering hard water can be essential for a safer water supply.

#3 Try a Magnifying Glass

If you’re testing your home water quality without a water test kit, remember to take note of water quality issues as soon as your water leaves the tap. 

Not all contaminant particles will be visible to the naked eye—but relying on your senses is crucial to establishing and fixing drinking water quality issues.

To perform a visual test, thoroughly clean and dry a clear glass bowl or drinking glass. Fill the container with water, place the container in bright light, and use a magnifying glass to take a closer look at the water.

If you notice floating particles, cloudiness, or foam that lasts more than a few minutes, your home water could be contaminated. While not all contaminants are harmful, establishing a baseline for visual water clarity can help you evaluate the effectiveness of any water purification solutions you test out to improve your home water quality. 

#4 Boil Your Water for a Dissolved Solids Test

Again, it can be difficult to observe dissolved solids, but even if you can’t see contaminants, you can still test for water impurities at home without a water test kit. Simply employ the boiling method:

  1. Thoroughly wash and dry a small pot or saucepan
  2. Fill the pot with one cup of water
  3. Place the pot on your stovetop, heating the water without a lid until it comes to a boil
  4. Turn off the heat once most of the water has evaporated
  5. Wait for the pot to cool completely

Once you’ve boiled off the water and waited for the pot to cool, run your fingers along the bottom of the pot. If you feel gritty, sticky, or chalky residue, your home water supply contains dissolved solids. 

Additional Factors to Consider

When assessing your water quality at home, you’ll also want to factor in a few external elements that may be affecting the quality of your water and how you should be testing it. These include:

  • Water source – Nutrient pollution can affect lakes, rivers, and streams, which are then absorbed into the ground. This may affect both public and private drinking water systems and pose serious health threats to those who drink the water. As such, it’s particularly important to look for nitrate contamination if your water comes from a groundwater source.2
  • Frequency of tests – According to the CDC, you should test the quality of your drinking water once a year and should test for coliform bacteria, nitrates, total dissolved solids, and pH levels. However, if you’ve experienced contamination within your water source or a recent repair to your water system, it’s recommended that you test your water more frequently.3 
  • Local health regulations – The EPA outlines the legal limits of 90 contaminants, as well as water testing schedules and methods that water systems must follow.4 The Safe Drinking Water Act has also allowed individual states to set standards for drinking water. As such, before testing your drinking water, it’s beneficial to consult with your state’s regulations.

Why Test Your Home’s Water Quality

As we mentioned, testing the water quality is important to help eliminate hard water and contaminants that may not only be harmful to your body but can potentially cause issues like plumbing damage, hard water stains, and more. While the water source and local health department regulations may impact the quality, water quality testing can also be essential to determine whether you need a water filter or water softener. Adding a water softener, like an ion exchange water filter, or even reverse osmosis system can help improve and make your drinking water safer.
