Q: How much iron does this kit detect?
A: It measures levels up to 5 PPM, plenty to diagnose all but the toughest iron problems. Additional testing may be needed before buying a water softener.
What we like
Watersafe’s 10-in-1 test kit falls short of a lab test, but it offers more actionable results than a TDS water tester. At a moment’s notice, you can check for lead and bacteria before making baby formula or any time you notice a change in your water quality. The testing process is more complex than with strips you dip into a glass of water. Some measuring is required, but the trade-off is accuracy. Watersafe test kits are an invaluable tool in anyone’s water quality toolbox.

Where Do Contaminants Come From?
Water can harbor thousands of dangerous contaminants, but chances are yours doesn’t. Typically, it’s a select group of substances that pose the greatest risk based on where your water comes from.
Drinking water comes from two sources — surface water such as lakes, rivers and streams — and groundwater — water stored in soil, rock and aquifers. In the US, about half of city water comes from each source. Nearly all private well water comes from underground.
With few exceptions, the make-up of groundwater is geologically stable. The substances that occur naturally in your area tend to remain the same long-term. If your last water test for arsenic was negative, chances are your next one will be, too — unless something changes above ground.
Your watershed — the area surrounding your home through which rainwater runoff flows — determines which contaminants are the most likely to reach your well. A heavy storm or melting snow, for example, can carry arsenic waste from an electronics factory down the road to your home, placing you at higher risk.
USGS maps show concentrations of hard water and geological contamination nationwide. Your local watershed map can help you identify potential sources of above-ground contamination near your well, such as:
- Hazardous waste disposal sites
- Farms and feedlots
- Sewage plants
- Golf courses
- Car washes
- Poorly maintained septic systems and more
City Versus Well Water — Assessing Your Contamination Risk
If you drink city water, most of the work is done for you. It’s checked for 90-plus EPA-regulated contaminants and disinfected at the source, so it’s biologically safe. Unless there’s a treatment error or a water main break, it won’t contain the bacteria, viruses or parasites that cause illness.
But it may have contaminants rarely found in well water, such as:
- Disinfectants, such as chlorine and chloramine
- Disinfectant by-products, including bromate and trihalomethane — known carcinogens
Despite their best efforts, public water supplies nationwide are routinely testing above legal limits for trihalomethane.
Dangerous contamination can also occur downstream, after water leaves the treatment plant. Lead, for example, can leach from aging service lines and pre-1986 plumbing in your home.
If you drink well water, there’s no need to test it for disinfectants or fluoride — natural deposits are rare. But wells are vulnerable to geological and chemical contamination.
Risks vary significantly by area. Arsenic, for example, is rare in Florida groundwater but common in Southern California, Northern Maine and Nevada. Radon contamination is widespread in North Dakota but unusual in Louisiana.
Homeowners in agricultural areas should be concerned about nitrates, pesticides, herbicides and bacterial contamination from livestock feces, while a factory, landfill or hazardous waste disposal site in your watershed could mean a wide range of chemical toxins in your water.
City and well water also have similar characteristics — hard minerals, for example, plague both. Researchers, meanwhile, are just now beginning to understand the impact of chemical pollution and how it contaminates both public and private water supplies. So-called forever chemicals like per- and polyfluoroalkyl substances, or PFAS, are thought to impact at least 30 million homes.
Why Do a Home Water Test?
The only way to know what’s in your water is to test it — some of the most hazardous contaminants are colorless, odorless and tasteless. Your annual municipal water quality report offers valuable information — but only home water testing tells you exactly what’s coming from your tap today.
It took officials in Flint, Michigan more than a year to discover that a treatment plant error caused dangerous levels of lead to leach from old underground service lines. Undetectable at the source, it nonetheless poured from Flint-area taps, poisoning scores of children.
Home water testing also provides a breakdown of your water chemistry — essential information to have when choosing a water filter. Iron, for example, is a healthy mineral. But did you know that it can ruin some water softeners? Were you aware that chlorine damages reverse osmosis filters? Or that low pH makes iron filters less effective? Knowledge is power — don’t buy a filtration system without it.
Types of Home Water Test Kits
Home water tests are broken down into five general categories.
- Microbiological tests for bacteria and parasites
- Hardness tests that measure the mineral content in your water
- Radiological testing for radon, uranium and radium
- Inorganic chemical tests for heavy metals like lead, mercury, chromium and arsenic
- Organic chemical testing that detects pesticides, herbicides, nitrates, industrial solvents, PFOA, trace pharmaceuticals and more
You can purchase kits that test for a single substance or dozens across several categories.
Popular types include:
1. Test Strips
Test strips contain dry chemical reagents that change color when activated by water. Just dip a strip in a sample and compare the color changes to the chart on the back of the bottle. You can test for 1-20 contaminants with single strips that cost just pennies each, but you’ll have to purchase the whole bottle for $8-$60.
2. Color Disc Kits
Color disc test kits are available for a broad range of substances. Water is combined with liquid or powdered reagents in a reusable plastic tube. The tube is placed in a viewing box with a color disk — hold it up to light and rotate it until the color matches the sample, and the contaminant value is displayed.
Color disk kits are generally more accurate than strips but they cost significantly more, testing for only one or two substances at $40-$90.
3. TDS (Total Dissolved Solids) Meters
TDS meters are hand-held, battery-operated water quality testers that estimate the parts per million of total dissolved substances in water. They’re helpful tools but with limitations.
TDS meters work by measuring electrical conductivity, so they only detect charged particles. Worrisome contaminants from motor oil and gasoline to pesticides and PFOA have no electrical charge.
Toxic heavy metals are charged, but they’re measured in parts per billion, not million. TDS meters aren’t sensitive enough to detect lead at a hundred times higher than the legal limit.
They’re also non-selective. The majority of dissolved solids are minerals. But meters don’t differentiate between calcium and iron — must-know information when buying a water softener.
So why should you have a TDS meter? The EPA doesn’t set a limit on total dissolved solids, but they recommend further testing if levels are above 500 PPM. High TDS can indicate water quality issues that would benefit from filtration. Hard water, for example — high levels of calcium and magnesium — leave limescale deposits in plumbing that can lead to higher utility bills and costly appliance repairs. Other minerals, like iron, give water a bitter, metallic taste and can encourage the growth of select bacteria.
TDS meters are also ideal for monitoring the performance of water softeners or reverse osmosis filters. Low readings verify they’re working — high readings suggest they need maintenance.
TDS meters are no substitute for a water test, but for as little as $10, they’re a quick, affordable and reliable way to help monitor your water quality.
4. Mail-in Test Kits
Mail-in test kits have drastically improved consumers’ access to professional water testing. Purchase one online and collect a water sample in the container provided. Mail it back to the company — they partner with independent labs nationwide to give you the most accurate results. Select from kits that test for up to 200 contaminants. Prices start at $20. Expect results in about three weeks.
Home Water Tests Versus a Lab
Drinking water test kits are convenient, but they have drawbacks.
Test strips and color disk kits are accurate when used properly, but they’re less specific than lab tests. The chemical reagents are sensitive and deteriorate quickly once opened. Strips, for example, should be discarded after 90 days, so purchasing a bottle of 60 is no bargain for a one-time test. And accuracy is subject to human error. Lab technicians spend years training to get it right, so even with the utmost care, poor technique can skew the results.
Certified drinking water laboratories specialize in water science. Recommended by the EPA, they use only the latest in proven technology and undergo rigorous annual inspections. Instead of just a number, you get a full report that helps you interpret what contaminant values mean. When accuracy matters, they’re the sound choice.
Choosing the Best Water Test Kit for Your Home
These are the three most important factors to consider when choosing a water test kit.
1. Your Water Source
Most city water is safe to drink, but it may expose you to:
- Hard minerals
- Trace pharmaceuticals and more
But the most important contaminant to test for in municipal water is lead. A powerful neurotoxin, it causes severe, irreversible developmental disorders in children. There is no safe level.
If you own a well, the CDC recommends annual testing for:
- Total dissolved solids
— plus a test every five years for the geological contaminants that are common in your area, such as radon or arsenic. States have additional guidelines.
If you haven’t checked your well water in the last few years, we recommend a comprehensive analysis that also includes tests for hard minerals and the contaminants common in your watershed.
2. Test Accuracy
When you’re dealing with dangerous toxins measured in parts per billion, it’s crucial to get the science right. Test strips for lead are a quick and inexpensive way to check tap water weekly if you’ve had issues in your area or want to verify that your water filter is performing, but only a certified lab gives you the most accurate results.
Among tests performed at home, strips are less accurate than color disk kits but a fraction of the cost. If accuracy matters but the health impact of the contaminant is low, tests strips are a good option. But if imprecise results could cost you, splurge for the color disk kit. The difference between two and three parts per million of iron, for example, can drastically affect a water softener’s efficiency.
Home water test kits cost as little as a few dollars for strips to $500 for comprehensive testing. As a general rule, purchasing a multi-contaminant panel brings the cost of each test down. You could drop hundreds on color disk kits for individual hard minerals, but you’ll spend less by buying a water hardness test kit and get more for your money.
Overspending on testing for low-risk contaminants doesn’t make sense. Yet we recommended being investment-minded. If you’re going to purchase a filtration system, the more you know about your water quality, the better buying decision you can make. Comprehensive testing isn’t cheap, but it’s more cost-effective than purchasing a water filter with bells and whistles you don’t need. And if you’re worried about your health, the peace of mind alone is worth the price.
1. Where can I get my water tested for free?
Several states offer free water tests for residents with wells. Others offer lead water test kits for homes with school-aged children. Your local branch of the Cooperative Extension Service may provide complimentary or reduced-cost testing. Some of the top water filter companies offer free basic tests without obligation — but you may be pressured to buy.
2. How do I test water for lead?
A lead water testing kit is the simplest solution. Strips are fine for screening purposes, but because of the extreme danger lead poses, we recommend final testing be done by a certified drinking water laboratory.
3. How do I test tap water?
Test your tap water with a city or well water test kit that screens for target contaminants.
4. How do I test well water?
Well water testing kits target contaminants common in wells. Why pay to test for substances like chloramine that are found only in city water?
5. How do I test for chemicals in water?
An organic chemical testing kit identifies most hazardous chemicals, including select emerging contaminants like PFOA and trace pharmaceuticals.
6. How much is a water test?
Test strips range from $8-$60 per bottle. Color disk kits average $50-$90. Mail-in kits start at $20 and up. Fees for water testing at a local laboratory vary and depend on the number of tests requested.
7. Are home water test kits accurate?
Home water test kits are less sensitive than lab tests but are accurate if used and stored as directed.
8. How often should I test my water supply?
The EPA makes no recommendations for testing city water at home except to say that lead testing is an option if you have kids in the house.
Homeowners are solely responsible for testing their wells. It’s required whenever real estate changes hands, but the CDC suggests testing for bacteria, nitrates, total dissolved solids and pH annually and whenever part of your well is repaired or replaced. States recommend additional tests based on the contaminant risks in your area.
