Just dip the strip in your water source and read the results with the color-coded scale that’s on the back of the package.

Tests for 14 Contaminants

Baldwin Meadows’ 14-in-1 water test kit might be the best option if you want to check for multiple contaminants and mineral levels.

You can check for alkalinity, pH, total hardness, and all manner of contaminants, including:

  • Iron
  • Copper
  • Lead

You can test as often—or as infrequently—as you’d like, and these test strips will still last two years (when stored correctly).

With plenty on hand, you’ll always know where your water quality stands.


  • Check for 14 different measures of water quality and safety
  • Easy to use dip test strips
  • Tests down to PPB (parts per billion) for some contaminants


  • Strips are only accurate within the first few minutes—so it’s tough to preserve the results
  • Detection down to PPM—not PPB like some more precise tests

2. AquaVial Water Test Kit- Detect E.Coli & Coliform, Use in Drinking Water, Wells, Pools, Hot Tubs or During Travels

AquaVial Detect E.Coli & Coliform, Use in Drinking Water, Wells, Pools, Hot Tubs or During Travels


  • detects Fecal Coliform Bacteria, including: E coli
  • easy to use and cost effective water quality test
  • rapid testing with the widest becteria detection range

Type: Vials

Features: Provides Bacterial results in 30 Minutes

Tests Down to One Bacterium Per ML

Some bacteria are harmful even in small amounts. The AquaVial test can detect one bacterium per ML of sample within 48 hours, per the manufacturer.

Color-Change Vials Give Quick Results

AquaVial’s kit comes with four tests that offer quick results. Each vial contains proprietary dye that reacts with specific contaminants.

All you need to do is add water to the vial and observe the color change: clean is yellow, contaminated is pink.

Tests for E. Coli and Coliform

E. Coli is the kind of bacteria you’ll often find in the human digestive tract… Coliform is, too, which means that in some cases, the bacteria isn’t dangerous.

But the presence of either could mean your water isn’t safe to drink—especially if it’s coming from a municipal source.

According to the EPA, if water tests positive for either contaminant, it needs to be addressed ASAP.

AquaVial tells you whether your water contains E. Coli and coliform, so you can take the appropriate follow-up steps to stay healthy and safe.


  • Checks for coliform and E. Coli
  • Easy visual test that’s simple to read
  • Four tests per package
  • Highly sensitive test


  • Doesn’t test for any other bacteria
  • Could signal positive when non-threatening coliform is present

3. Water Quality Tester, Accurate and Reliable, HoneForest TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm

This is an excellent tool for checking outdoor water sources when you don’t have a glass on hand.

Multi-Function Features

HoneForest’s water quality tester measures three things:

  • Total dissolved solids
  • Electrical conductivity (EC)
  • Temperature

Instead of doing multiple tests or purchasing various kits, you can do it all with one product.

Digital Readout with an LCD Screen

Forget color-matching and guessing on results: the LCD screen on this tester gives you an easy answer.

The backlit LCD shows how many parts per million contaminants are in your water. Just stir gently, and the results pop up within seconds. It even changes color—green for under 40ppm, red for over 40.

Reading the temperature is simple, too, and so is the electrical conductivity (EC) readout.


  • No calibration necessary: comes auto calibrated
  • Easy visual readings
  • Tests temperature, EC, and TDS
  • Auto shutoff to conserve battery life


  • Doesn’t test water pH
  • Not being able to calibrate it can be a problem if you suspect a discrepancy

Unlike Health Metric’s heavy metal kit, this one covers nine contaminants for tap or well water.

Each kit checks for lead, bacteria, copper, bacteria, chlorine, nitrite and nitrate, and pH, alkalinity, and hardness.

You get a comprehensive water checkup in one kit—plus doubles of the chlorine, nitrite and nitrate, and 3-way tests.

Measures Low Levels of Lead and Copper

Like similarly competitive tests, Health Metric’s measures low-level amounts of lead and copper. This way, you can tell if there are even trace amounts in your drinking water.


  • Test results are color-based and easy to read
  • Multiple tests for certain elements for repeat checks
  • Quick tests—and bacteria test in 48 hours


  • The lead test checks for valence metals—so it will come back positive for other metals, too
  • Test vial is small and hard to work with

5. First Alert WT1 Drinking Water Test Kit

First Alert’s water test kit scans for water hardness and pH, plus pesticides, lead, chlorine, nitrites and nitrates, and bacteria (like E. Coli).

With one kit, you can verify your water safety and quality.

Separate Test Components

First Alert’s test is a one-time use type, but some components are separate. For example, the Lead test is separate from the pesticide test strip.

With dual testing options, you can do one test now and save the others for later. A water hardness test kit is useful on its own. But depending on what contaminants you suspect in the water supply, the ability to use whichever test you need at the moment could be helpful.


  • Don’t have to do all the tests at the same time
  • Follows EPA standards
  • Checks for 7 contaminants
  • Takes ten minutes for results


  • One-time use kit

 Tests can be tough to handle and read

If there’s coliform in your water, the Coliform Bacteria Test Kit will signal it. Then, you can take the necessary steps to clean your water so it’s safe.

The test measures total coliform—not E. Coli separately.

Large Test Vial Makes Reading Results Easier

The “test vials” are actually small jars with the Health Metric test. That Means you fill them up, shake, and can easily tell what the result is.

Larger jars mean there’s less confusion over what color the water is or how to interpret your water test results.

Just check the jars after 48 hours to see if the bacteria (if any) have consumed the “food” dye.


  • Large test jars
  • Simple color-change results
  • Two tests per package
  • Tests for total coliform


  • Not the most economic choice for frequent testing
  • Doesn’t measure E. Coli specifically

What Are the Types

Water test kits for consumers are easy to use and usually offer quick results. Different types are available, however, so it’s essential to know what your options are.

Some water test kits involve dip strips. You capture water in a small container, then dip the strip in to obtain a sample. Reading the results often involves color-matching to a key, which indicates either parts per million (PPM) or parts per billion (PPB).

Bacteria test kits involve a solution which you mix with your water sample. You must use cold water for these tests—and wait 48 hours to check results—to see whether there’s bacteria in your water.

Other tests are digital, checking the water with a thermometer-like device. Many digital options include thermometers, too.

Still other kits require you to obtain water with a dropper or pipette. Then, you place water droplets on a paper or card. These tests work the same as dip strips, in that you must read the color results afterward.

Some types of tests are positive or negative, such as lead tests. These will turn back either a “clean” or “contaminated” result. If you want to know specific PPB or PPM, then laboratory testing will probably be necessary.

How to Pick the Perfect One for Your Needs

Not sure what type of water test kit is right for you? Here’s how to determine what the best water test kit is for your water supply.

Features of a Good Water Test Kit

You want a water test kit that’s reliable, of course. But the more precise, the better, in most cases. After all, one bacterium is different than millions of bacteria.

Looking for precision in your water test kit is a good idea. Check whether it’s PPM or PPB for the results—and whether the results are on a scale or just a simple yes/no reading.

Checking for multiple measures of water safety is also helpful. Regardless of what you suspect might be in your water, scanning for a handful of heavy metals, bacteria, and other particles can give you a better idea of what you’re drinking.

And finally, the kit should be easy to use. That will depend on how familiar you are with tap water test kits and reading results. In general, the larger the containers and the simple the directions, the better.

Considerations Before You Buy

Here’s what to think about before buying your home water testing kits for drinking water:

  • What contaminants you want to check for.
  • How much you want to spend.
  • How often you plan to test your water.
  • What type of water you have—whether well, municipal, or some kind of science project.
  • Whether a yes/no result or a more specific reading will be most useful.
  • What follow-up testing will be necessary if you get an undesirable result.
  • If it’s necessary to check for certain things—like chlorine—if you already have evidence they’re there.
  • What you plan to do with the results—filter your water, hire an expert, drill a new well?

As far as where to buy water test kits, you can find them online. Also, many hardware and plumbing stores carry testing kits, too.

How Does It Work?

Water test kits use the same technology that laboratories use to get accurate water quality and safety results.

Test strips or powders react when they come into contact with a certain contaminant. The chemicals change color—or activate a digital result on your device’s screen—to show the element is present.

The process goes like this:

  • The water saturates the strip or test powder.
  • The chemicals in the test detect a contaminant—like lead or chlorine.
  • The chemical reaction changes the color of the test paper, strip, or container.
  • You check the color of the paper or liquid against the manufacturer-supplied results panel.


What are the perks of using a water test kit? We’re glad you asked.

There are tons of reasons it’s a good idea to use a water test kit—so here are a few:

  • You know whether your water has anything harmful in it.
  • A test kit can show whether the water is safe to drink.
  • Testing the water tells you what types of filtration will be best.
  • Testing before and after filtering your water shows you how effective your filter is.
  • You can determine whether the city is adding chemicals to your water—like fluoride.
  • You can figure out whether your H2O source is “hard”—with lots of minerals floating in it.
  • Test kits can tell you the pH of your water.
  • Knowing the pH helps you determine whether to adjust it up or down.
  • You’ll figure out the source of any weird flavors or smells (like chlorine).
  • A water test kit is a cheap way to see if the water is safe (compared to drinking it and getting sick).
  • Testing the water regularly can indicate if there’s a problem, like contamination in city sources or in your well.
  • When you test the water, you can see if your filter needs changing based on how “clean” the water is.
  • Figuring out if the H2O has healthy (or unhealthy) minerals is possible with many water tests.
  • You don’t need to ship your water sample off for most tests!
  • You can DIY the test in the comfort of your home—and read the results without a degree in water science.
  • Testing and re-testing is possible anytime if you order enough supplies.

You can use trial and error to figure out what filters or products produce the safest, cleanest, tastiest water.

How to Use It

How you use your water test kit will depend on the specific manufacturer instructions.

It’s essential that you follow the directions carefully, including things like only using cold water for bacteria tests—and waiting 48 hours to read the results.

But in general, you should submerge the test in the water for only a few seconds. Then, you should read the results within the timeframe the directions indicate.

Some tests need to be read immediately—if the water starts to evaporate, the results won’t be accurate anymore. Some tests take ten minutes to generate a reliable result. Others—like the bacteria test—take longer.

Overall, though—just take the manufacturer’s advice and read the instructions they provide for the most specific information.


a. How Frequently Do I Need to Test My Water?

Many experts recommend testing your water every six months. Of course, you can check more frequently if you suspect a problem, such as if your water quality or taste has changed.

b. How Accurate Are the Water Test Kits?

In general, water test kits are accurate for measuring down to PPM or PPB. Since most tests follow EPA standards, you can generally trust the accuracy.

That said, if you get a suspicious—or dangerous—result, it’s best to consult a professional for help.

c. What Kind of Kit Can I Use to Test Water Contamination?

Well, it depends on what type of contaminant you want to check for!

You can check for heavy metals like lead and copper, bacteria like E. Coli, additives like chlorine and fluoride, and just about anything else you want to investigate.
