Well Water Test Kit: How to Test Your Private Well Water the Right Way
A well water test kit helps you collect a water sample from your home and send it to a laboratory for analysis. It is one of the most practical ways to check whether your private well water contains bacteria, nitrates, minerals, radon, arsenic, or other concerns that may affect water quality.
The important part is this: the kit is only the collection step. For reliable results, your sample should be tested by a qualified laboratory, not just checked with a basic at-home strip. The CDC recommends using a state-certified laboratory for well water testing, and the EPA advises private well owners to test at least once a year for total coliform bacteria, nitrates, total dissolved solids, and pH.
If you live in New Hampshire or the Seacoast area, Seacoast Analytical makes the process simple. You can order your well water test kit, follow the included sample guide, then mail or drop off your sample for laboratory testing.
What Is a Well Water Test Kit?
A well water test kit is a package that gives you the bottles, instructions, and submission details needed to collect a water sample correctly.
A typical kit may include:
- Sample bottles for specific types of testing
- Collection instructions
- Labels or paperwork
- Mailing or drop-off instructions
- Guidance on timing and handling
This matters because different water tests may require different bottles, collection methods, or delivery windows. For example, a bacteria sample needs to be handled differently from a mineral or radon water sample. Following the kit instructions helps prevent contamination and delays.
Seacoast Analytical’s test kit process is built around three simple steps: pick up or order your kit, follow the guide included with the kit, then mail in or drop off your sample. Their Lee, NH location also offers 24/7 pickup and drop-off access for test kits and samples.
Can You Test Well Water at Home?
Yes, you can collect a well water sample at home. But there is a difference between testing water at home and collecting a sample at home for lab testing.
Basic store-bought strips may show general indicators like hardness, pH, or chlorine. They may be useful for a quick check, but they cannot replace certified laboratory testing when you need dependable drinking water results.
A lab-analyzed well water test kit is different. You collect the sample at home, then the laboratory performs the analysis using proper testing methods. This is the better route when you want to check your drinking water for health-related or home system concerns.
For private well owners, this is especially important because private wells are not regulated the same way public water systems are. The CDC explains that well owners are responsible for testing their own well water to make sure it is safe to drink.
If you are unsure what to test for, start with certified well water testing through a local lab that can guide you based on your home, well type, and area risks.
How to Take a Water Sample for Testing a Well
To take a water sample for testing a well, use the bottles provided in your test kit and follow the instructions exactly. Do not use your own containers unless the lab specifically tells you to do so.
Here is the general process:
- Read the sample guide first
Do this before turning on the faucet or opening the bottles. Some tests have specific timing or handling requirements. - Use the correct bottle for each test
Do not swap bottles between tests. Each container may be prepared for a specific type of analysis. - Choose the right water source
In many cases, the sample should come from a commonly used cold-water tap. Follow your lab’s instructions. - Avoid touching the inside of the bottle or cap
This helps prevent accidental contamination, especially for bacteria testing. - Fill the bottle as instructed
Some bottles need headspace. Others need to be filled to a specific line. - Label the sample clearly
Include the required details so the lab can process the sample correctly. - Send or drop off the sample quickly
Some samples must be received within a certain time frame to remain valid.
Seacoast Analytical includes sample collection instructions with its kits. You can also review their water testing FAQs for sample collection guidance before submitting your water.

How Much Does Well Water Testing Cost?
The cost of well water testing depends on what you need tested.
A basic water test may cost less than a broader package that checks for bacteria, minerals, metals, radon, arsenic, or other contaminants. Pricing can also vary if you need specialty testing, additional samples, courier pickup, or fast turnaround.
In general, the answer to how much does well water testing cost depends on these factors:
- The number of contaminants being tested
- Whether the test is basic or comprehensive
- Whether radon water testing is included
- Whether arsenic or other metals are included
- Whether the sample requires special handling
- Whether you need additional testing based on local risks
- Whether you are testing for a home sale, annual check, or treatment monitoring
For many homeowners, the better question is not just “how much is a well water test?” It is “which test package gives me the information I actually need?”
Seacoast Analytical offers different testing package options and provides a rate card through its FAQ page. For unique testing requests, the lab recommends contacting the team directly for specific sample requirements and rates.
How Often Should You Get Your Well Water Tested?
You should test private well water at least once a year for key water quality indicators. The EPA recommends annual testing for total coliform bacteria, nitrates, total dissolved solids, and pH levels. The CDC gives similar yearly testing guidance and recommends checking for other germs or chemicals based on where you live.
You should also test sooner if:
- Your water has a new smell, taste, or color
- Your area has had flooding or major storms
- You recently repaired or replaced part of your well system
- A child, older adult, pregnant person, or nursing person lives in the home
- There are known groundwater concerns nearby
- You are buying or selling a home with a private well
- You installed or changed a water treatment system
Seacoast Analytical’s FAQ also notes that the EPA and New Hampshire Department of Environmental Services recommend a Basic Test yearly, Standard Analysis every three years, and radon monitoring every three to five years.
What Should Private Well Water Be Tested For?
The right testing package depends on your well, location, plumbing, and water concerns.
Common private well water tests may include:
- Total coliform bacteria
- E. coli
- Nitrates
- pH
- Total dissolved solids
- Hardness
- Iron
- Manganese
- Sodium
- Lead
- Copper
- Arsenic
- Radon in water
- Uranium or other local contaminants, depending on area risk
Some water issues are obvious. Staining, odor, salty taste, cloudy water, or scale buildup can point to minerals or other water quality concerns. Other issues, including bacteria, arsenic, nitrates, and radon, may not be visible, smelled, or tasted.
That is why routine testing matters. Clear water does not always mean fully tested water.
If arsenic has been found in your water before, or if you have a treatment system installed, it may also be worth asking about an arsenic monitoring program to keep track of water quality over time.
Can You Get Well Water Tested for Free?
In some areas, local health departments may offer limited private well testing or guidance. The EPA notes that local health departments may provide private well testing for free in some cases.
However, free testing is not always available, and it may not cover every contaminant you need to check. Some programs only test for a small set of concerns, such as bacteria or nitrates. Others may be available only during specific events, grant programs, or public health investigations.
If you need a full picture of your drinking water quality, especially for a real estate transaction, treatment system monitoring, radon concern, arsenic concern, or annual private well check, a laboratory test kit is often the more complete option.
Why Use a Certified Drinking Water Laboratory?
A certified drinking water laboratory gives you more than a quick result. It gives you a formal report that can help you understand what is in your water and what to do next.
This is especially useful when:
- You rely on a private well for drinking and cooking
- You are buying a home
- You are selling a home
- You have a baby, older adult, or pregnant person in the home
- You installed a water treatment system
- Your water suddenly changes
- You need documentation for a home inspection or treatment provider
Seacoast Analytical lists several credentials, including New Hampshire Environmental Laboratory Accreditation, Maine Laboratory Accreditation, National Radon Safety Board certification, and Maine Radon Service Provider certification.
You can learn more about their laboratory credentials on the certifications page.
