We understand that millions of American households still rely on private wells as their primary water source, despite the expansion of municipal water systems.
If you’re among these well owners, the information we’re about to share about well water testing is absolutely crucial for your family’s safety.
Our team of master plumbers and water quality experts has discovered that while soil naturally filters groundwater, many harmful contaminants can still infiltrate your well water supply.
Through our extensive testing and analysis across hundreds of private wells, we’ve identified numerous impurities that make water unsafe for consumption.
Drawing from our collective decades of hands-on experience in water quality assessment and treatment, we’ve developed this comprehensive guide to help you understand how to test your well water effectively. We’ll share our professional insights about:
As the Filtered Water Guide team, we’re committed to helping you ensure your well water is safe and clean for your household’s needs.
In our years of testing private wells, we’ve found that regular water testing isn’t just recommended—it’s crucial for well owners. Based on our extensive field experience, this is particularly important if you’re using well water for drinking.
The primary concern our team focuses on is protecting your family’s health. Through our testing, we’ve consistently found that natural ground filtration often fails to remove harmful substances like pesticides, bacteria, salts, and hydrocarbons before they reach your well water source.
Beyond health concerns, we’ve observed how untreated well water can create numerous household problems. In our assessments, we regularly see:
The good news is that through our experience, we’ve found that virtually every well water impurity can be identified through proper testing. Once detected, there are proven solutions to address these issues and protect both your family’s health and your home.
Through our collaboration with environmental agencies and our own testing experience, we’ve identified six major categories of well water contaminants, as outlined by the EPA:
In our testing work, we frequently detect harmful bacteria like E. coli, which comes from soil, sewage, and animal waste. We also test for various viruses and parasites that can contaminate well water.
Our analysis often reveals high levels of nitrates, primarily from agricultural fertilizers and waste materials. We’re particularly careful about monitoring these as they convert to nitrites, which our experts have found to be especially dangerous for children.
Through our extensive water quality testing, we regularly identify metals including cadmium, arsenic, antimony, chromium, lead, iron, copper, and selenium. These typically enter well water through corroded pipes, nearby mining operations, and industrial processes.
For more detailed information, check our specialized guides on testing for copper and testing for heavy metals.
Our testing routinely identifies chemicals from household products and industrial processes. We find substances ranging from inks and dyes to pharmaceuticals, paints, solvents, sealants, and disinfectants in well water samples.
In our analysis work, we test for radioactive elements that occur both naturally and through human activities. Our team commonly finds uranium and radium in well water, particularly in certain geological regions.
While beneficial in small amounts for dental health, we’ve found that excessive fluoride levels can be harmful. Our testing helps ensure your well water maintains safe fluoride concentrations.
Based on our extensive field experience and in line with the guidelines established by the New York State Department of Health, we strongly recommend annual well water testing. Through our testing work, we’ve found that bacterial contamination poses the most immediate health risk, making yearly testing essential.
While some contaminants can be monitored every three to five years, our team typically recommends comprehensive annual testing. We’ve found that since you’re already testing for bacteria, it’s practical and beneficial to check for other contaminants simultaneously.
In our years of well water analysis, we’ve identified several critical situations that require immediate testing:
Through our extensive experience in water quality assessment, we’ve worked with two primary testing approaches:
Our team has evaluated numerous home testing options, and we’ve found they offer a quick initial assessment of your well water quality. Most kits use test strips, though some contaminants (like bacteria) require different testing methods.
A prime example is the ‘Watersafe Drinking Water Test Kit‘, which we’ve used extensively in our assessments. It tests for 10 key contaminants:
Through our testing experience, we’ve found these kits work best as preliminary screening tools. While they’re not as precise as laboratory analysis, they can help identify when professional testing is needed.
Important Note: Based on our field experience, we always recommend following the kit instructions precisely. Each manufacturer may have specific requirements for accurate results.
For the most comprehensive analysis, our team always recommends using a professional water test kit. Through our experience, we’ve found that laboratory testing typically screens for over 200 different contaminants, far more than home test kits can detect.
While professional testing comes at a higher cost—often 10 times more than home testing kits—we believe the detailed results justify the investment. When shipping samples, proper handling is crucial. The ‘Safe Home Ultimate Water Quality Test Kit‘ provides specially designed containers that prevent leakage during transport.
For local testing, we recommend using thoroughly cleaned mason jars. Based on our testing experience, multiple rinses are essential to prevent any residue from affecting the results.
When our testing reveals contaminants in your well water, we recommend several proven treatment options:
Here are the questions we receive most frequently about well water testing:
What’s the cost of well water testing? We found that well water test prices vary significantly based on the testing method. From our experience, DIY home testing kits typically range from $25 to $40, while professional laboratory analysis can exceed $300.
How quickly will I receive my lab test results? Through our partnerships with testing facilities, we’ve observed that on-site laboratory testing usually delivers results within 2-4 hours, depending on laboratory workload. For mail-in testing services, you can expect digital results within 2-4 days after your sample reaches the laboratory.
Should I be concerned about well contaminants? Based on our extensive testing experience, many contaminants can pose health risks when consumed regularly or in quantities exceeding safety thresholds. For detailed information about specific contaminant health impacts, we recommend reviewing this EPA webpage.
What solutions exist for contaminated well water? We recommend installing a well water filtration system on your main water supply line from the well pump to effectively address contamination issues. For comprehensive guidance on treatment options, check out our detailed well water treatment guide
As the Filtered Water Guide team, we’ve analyzed countless water sources over the years, and we’ve reached an important conclusion: virtually no water source is completely free from contaminants. This reality is particularly true for well water systems. We’ve seen firsthand how drinking untreated well water can potentially compromise your family’s health—a risk we take very seriously.
Our experience has shown that water testing provides invaluable peace of mind through concrete data about your well water quality. For homeowners with well water systems, we strongly recommend following the EPA testing frequency guidelines outlined above. Once you identify any problematic contaminants in your water supply, you can take informed steps to address these specific issues effectively.
