What Contaminants Should You Test For in Your Home
Understanding which contaminants might be lurking in your water is essential for selecting the right testing kit for your specific needs. Here’s what you should be looking for when testing your home’s water quality.
Common Chemical Contaminants
Chemical contaminants often enter water supplies through industrial waste, agricultural runoff, or aging infrastructure. Test for lead and copper, which can leach from old pipes and cause serious health issues, especially in children. Check for chlorine and chloramines used in municipal treatment that can affect taste and irritate skin. Monitor for pesticides and herbicides that commonly infiltrate groundwater in agricultural areas. Don’t forget nitrates and nitrites from fertilizers, which are particularly dangerous for infants. Finally, test for PFAS (per- and polyfluoroalkyl substances), these “forever chemicals” are increasingly concerning in many water supplies.
Biological Contaminants
Biological contaminants pose immediate health risks and require regular monitoring. Test for coliform bacteria, including E. coli, which indicate fecal contamination and potential pathogens. Check for cryptosporidium and giardia parasites that cause gastrointestinal illness and are resistant to chlorine disinfection. Monitor for legionella bacteria, which can cause Legionnaires’ disease when aerosolized in showers. Watch for algal toxins in areas near lakes or reservoirs, especially during warmer months. Private well owners should test more frequently for these contaminants as they lack municipal treatment safeguards.
Physical Properties to Monitor
Physical properties affect water’s appearance, taste, and how it interacts with your home’s systems. Test pH levels to ensure your water isn’t too acidic or alkaline (ideal range: 6.5-8.5). Check total dissolved solids (TDS) which affect taste and can indicate contamination when levels suddenly change. Monitor hardness levels caused by calcium and magnesium, which can damage appliances and plumbing. Test turbidity (cloudiness) which can shield microorganisms from disinfection processes. Watch for unusual colors, odors, or sediment that might signal contamination or pipe corrosion requiring further investigation.
How to Choose the Right Water Testing Kit for Your Needs
Selecting the ideal water testing kit requires understanding your specific concerns and requirements. Here’s how to make the right choice for your household water quality needs.
Considering Your Water Source
Your water source directly determines which contaminants you should test for. City water users should focus on lead, chlorine, and pH testing, as municipal systems already filter many contaminants. Well water requires more comprehensive testing for bacteria, nitrates, pesticides, and heavy metals since it lacks municipal treatment. If you live near industrial areas or farms, prioritize testing for industrial chemicals or agricultural runoff that might affect your specific water supply.
Determining Testing Frequency
Establish a regular testing schedule based on your water source and household needs. Municipal water users should test annually for basic contaminants and after plumbing work or water quality notices. Well water requires quarterly bacteria testing and annual comprehensive testing for chemicals and metals. If you notice changes in water taste, odor, or appearance, test immediately regardless of schedule. Households with pregnant women, young children, or immunocompromised individuals should test more frequently to ensure ongoing safety.
Balancing Cost vs. Comprehensiveness
Match your testing approach to your budget and concerns without compromising essential safety checks. Basic test strips ($10-$30) work well for routine monitoring of pH, chlorine, and hardness. Mid-range digital meters ($50-$100) provide more accurate readings for specific contaminants of concern. For complete peace of mind, invest in comprehensive lab-analysis kits ($100-$300) annually while using less expensive options for interim testing. Consider subscription services that spread costs while ensuring regular monitoring of your water quality throughout the year.
How to Use Home Water Testing Kits Properly
Getting accurate results from your home water testing kit requires following specific procedures. Let’s break down the essential steps to ensure you’re testing your water correctly and interpreting the results accurately.
Preparation Steps
Before testing your water, wash your hands thoroughly with soap and water to avoid contamination. Gather all testing materials and read the instructions completely—each kit has specific requirements. Remove any aerators or filters from your faucet and let cold water run for 2-3 minutes to flush the pipes. Avoid touching the inside of collection containers or test strips with your fingers to maintain sample integrity.
Sample Collection Best Practices
Always collect samples from the tap you most frequently use for drinking or cooking. When filling containers, hold them at an angle to minimize bubbles and fill completely unless instructions specify otherwise. For certain tests, you’ll need to capture the “first draw” of water that’s been sitting in pipes overnight—particularly for lead testing. Label multiple samples clearly with collection time, date, and location to prevent confusion during testing.
Reading and Interpreting Results
Follow the kit’s timing instructions precisely—testing too early or late can skew results. Compare color changes on test strips to the provided chart in good lighting (natural light works best). Digital meters should display readings immediately, but verify the units of measurement (ppm, mg/L). Document all results in a logbook or spreadsheet for historical comparison. If readings approach or exceed EPA limits, consider confirmatory testing through a certified laboratory.
When to Seek Professional Water Testing Services
While home water testing kits offer convenience and affordability, certain situations warrant professional water testing services. You should consider hiring professionals when:
- Severe contamination is suspected – If your initial home tests show concerning levels of contaminants or you notice unusual tastes, odors, or colors in your water, professional testing can provide confirmation and detailed analysis.
- After natural disasters – Floods, hurricanes, or earthquakes can compromise water systems and introduce contaminants. Professional testing ensures your water supply remains safe following these events.
- When buying a new home – Professional water testing should be part of your home inspection process, especially for properties with private wells or older plumbing systems.
- For legal documentation – If you’re involved in disputes regarding water quality or need documentation for legal purposes, professionally certified results carry more weight than DIY testing.
- When selling your home – Professional water quality certification can increase buyer confidence and property value, particularly for homes with private water sources.
- For comprehensive analysis – When you need to test for specific contaminants not covered by home kits, such as radionuclides, pesticides, or industrial chemicals, professional services offer specialized testing options.
- Following a positive home test – If your home kit detects contaminants, professional testing can confirm results and provide more precise concentration levels to guide remediation efforts.
- For well inspections – Annual professional testing is recommended for private wells, as they’re more vulnerable to contamination and aren’t regulated by municipal water treatment standards.
