6 Water Quality Test Kits For Well Water That Identify Hidden Dangers
Well water can hide contaminants like lead and bacteria. Our review of 6 test kits helps you find the right one to ensure your family’s drinking water is safe.
You turn the spigot and the trough fills with clear, cold water from your well, the lifeblood of your entire homestead. But what you can’t see can cause the most harm to your family, your livestock, and your crops. Testing your well water isn’t a luxury; it’s a fundamental part of responsible land stewardship.

Tap Score Advanced Test: Lab-Grade Analysis
When you need a definitive, no-questions-asked baseline of your water quality, this is where you turn. Tap Score offers a mail-in lab test that is incredibly comprehensive, checking for hundreds of contaminants, including heavy metals, volatile organic compounds (VOCs), pesticides, and even radiologicals. Think of this as the master blueprint for your well.
This isn’t your monthly check-up kit. It’s the one you use when you first buy a property, if you have a sudden, unexplained health issue in your family or animals, or if a new industrial or agricultural operation starts up nearby. The detailed report doesn’t just give you numbers; it explains what they mean in plain language, which is invaluable for making big decisions, like whether you need a whole-home filtration system.
The tradeoff, of course, is cost and time. It’s one of the more expensive options, and you’ll wait for the results to be processed by their certified lab. But for a complete and legally defensible picture of your water, the investment provides unparalleled peace of mind.
Health Metric 16-in-1 Kit for Fast Results
Sometimes you just need a quick snapshot, not a full-length documentary. The Health Metric 16-in-1 kit is a set of simple test strips that gives you results in minutes, right in your kitchen. It covers the common culprits: hardness, pH, chlorine, nitrates, nitrites, and some key metals like iron and copper.
This kit is perfect for routine monitoring. Did you just have a week of heavy rain? Dip a strip to see if your nitrate levels spiked. Did you just install a new water softener? Check the hardness to see if it’s working. It’s an excellent early-warning system that can alert you to changes that might warrant a more serious lab test.
However, it’s crucial to understand the limitations. These strips provide a range, not a precise measurement. A color chart that shows "low," "medium," or "high" is a useful indicator, but it’s not the same as a lab report that gives you an exact parts-per-billion reading. Use it for frequent check-ins, not for diagnosing a serious contamination issue.
Safe Home Ultimate Kit for Heavy Metal Scans
If your property is near old industrial sites, down the road from a landfill, or has plumbing from before the 1980s, your primary concern might be heavy metals. The Safe Home Ultimate Kit is a certified lab test that focuses intensely on contaminants like lead, arsenic, cadmium, and mercury. These are the silent dangers that build up over time in your body, your animals, and your soil.
This test is more targeted than a broad-spectrum analysis like Tap Score but far more accurate than a simple DIY strip. It provides the precise, reliable data you need if you suspect a specific type of contamination. For instance, if you know the old orchard up the hill used lead-arsenate pesticides for decades, this is the test that confirms whether that legacy is leaching into your groundwater.
Getting this level of detail is critical for more than just drinking water. Heavy metals can be absorbed by garden vegetables, impacting the food you grow. For a hobby farmer focused on self-sufficiency and healthy produce, knowing your heavy metal status is non-negotiable.
Varify Complete Kit: Bacteria & Pesticides
Ensure your drinking water is safe with the Varify 17-in-1 Water Test Kit. Easily test for lead, bacteria, chlorine, and more using our simple, color-coded strips and included bacteria tests.
This kit hits two of the biggest concerns for any rural property: microbial life and chemical drift. The Varify Complete Kit combines DIY strips for common parameters with a mail-in lab test specifically for bacteria (like E. coli) and a wide range of common pesticides and herbicides.
This is a fantastic middle-ground option. You get the immediate feedback from the strips for things like pH and hardness, while getting lab-certified accuracy for the most pressing farm-related threats. If your well is shallow, located near a septic system, or downhill from a conventionally farmed field, this test is designed for your exact situation.
The dual approach is smart. Bacteria can appear suddenly after a flood or septic issue, and you need a reliable "yes" or "no" answer. Pesticides, on the other hand, are a slow-moving threat, and having a lab screen for them annually gives you a clear picture of any potential contamination from neighboring properties.
WaterCheck Standard: A Trusted Mail-In Option
The WaterCheck Standard test is a workhorse. It’s a mail-in lab test that covers a solid range of over 75 common contaminants, including bacteria, nitrates, and heavy metals. It’s less exhaustive than the most premium lab tests but provides a significant step up in accuracy and reliability from any at-home strip kit.
Think of this as your ideal annual physical for your well. It’s comprehensive enough to catch most common problems before they become serious and provides a consistent record you can track year over year. If you see your nitrate levels slowly creeping up, you have time to investigate the cause—be it your compost pile, your septic field, or a neighbor’s fertilizer use.
This is a great choice for established homesteaders who have already done a deep-dive test in the past and now need a reliable, affordable way to ensure nothing has changed. It balances detail with cost, making it a sustainable part of your yearly farm maintenance routine.
SimpleLab Kit: Testing for Farm Runoff Issues
SimpleLab offers a variety of tests, but their specialized panels for agricultural water are particularly useful. A test like their "Tap Score Agricultural" package is designed to look for the specific calling cards of farming activities: high levels of nitrates, nitrites, coliform bacteria, and salinity.
This is the test you choose when your biggest concern is what’s happening on the land around you—or even your own. High nitrate levels, often from fertilizer or manure runoff, can be dangerous for infants and young livestock, causing "blue baby syndrome." High salinity can stunt crop growth and damage your soil over time.
Instead of paying for a broad test that checks for industrial solvents you know aren’t a risk, this lets you focus your money on the most probable threats in a rural environment. It’s a practical, targeted approach for anyone managing land.
Pro-Lab Lead Test: A Specific Contaminant Check
Sometimes, you don’t need to test for everything. You just need to answer one very important question: "Do I have lead in my water?" If you live in an old farmhouse with original plumbing or have any reason to suspect lead, a specific test like the Pro-Lab Lead Test is the most direct and cost-effective tool.
This kit provides a simple, EPA-approved method to get a lab-verified answer for lead contamination alone. There’s no point in paying for a 150-contaminant panel if your only real concern is the lead solder in your copper pipes. This is about surgical precision.
This is also a great follow-up test. If a broader strip test indicated the presence of heavy metals, you can use this to confirm if lead is the specific culprit. It’s a smart way to manage your testing budget by focusing resources where they’re needed most.
PurTest Bacteria Kit: Essential Coliform Check
Of all the potential well water contaminants, bacteria is often the most immediate threat to health. The PurTest Bacteria Kit is an easy-to-use, at-home test that specifically checks for coliform bacteria, including E. coli. A positive result is a clear and immediate signal that your water is unsafe for consumption without treatment.
This test is an essential part of any well owner’s toolkit. You should run a test after any event that could compromise your wellhead, such as flooding, nearby excavation, or maintenance on your well pump. It’s also wise to test if anyone in the household experiences unexplained stomach issues.
While it won’t tell you which bacteria are present, a positive result is all you need to know to act. The answer is binary: the water is either safe from a bacterial standpoint, or it needs to be boiled and the source of contamination found and fixed. For a quick, reliable go/no-go on safety, this test is indispensable.
Ultimately, the right test depends entirely on your property’s history, your budget, and your specific concerns. You can’t protect your family, your animals, or your land from a threat you don’t know exists. Start with the test that best matches your risk profile, and make water quality monitoring a regular part of your farm’s rhythm.
