Receiving your well water test results can be overwhelming, especially if you’re unfamiliar with the scientific terms and parameters. Understanding these results is crucial for ensuring safe drinking water. In this guide, we’ll help you interpret common well water test parameters and explain what they mean for your water quality and safety.
Is My Well Water Safe to Drink?
The safety of your well water depends on the presence and concentration of contaminants. Here’s how to evaluate the most common parameters:
- Total Coliform and E. coli Bacteria: Coliform bacteria are used as indicators of possible contamination from animal or human waste. If detected, it’s a sign that your well water may be unsafe. E. coli presence confirms fecal contamination, requiring immediate action.
- Nitrate and Nitrite Levels: High levels of nitrates or nitrites can be dangerous, especially for infants and pregnant women. They are often linked to agricultural runoff or septic system leakage.
- Lead and Arsenic: These toxic heavy metals pose serious health risks, even at low levels. Lead is commonly linked to old plumbing systems, while arsenic is naturally occurring in some geological areas.
- pH and Alkalinity: Ideal drinking water has a pH between 6.5 and 8.5. A low pH can be corrosive to plumbing, while a high pH may indicate chemical contamination.
Understanding Parameter Explanations
Well water test reports often include detailed parameter explanations. Here’s how to interpret them:
- Maximum Contaminant Level (MCL): The highest level of a contaminant allowed in public water systems, set by the Environmental Protection Agency (EPA). While these don’t apply to private wells, they provide useful safety guidelines.
- Action Level: The concentration at which a contaminant poses a health risk, triggering a need for remediation or filtration.
- Non-Detect (ND): This means the contaminant was not found in your water sample at the test’s detection limit.
What to Do If Your Water Fails the Test
If your well water fails to meet safety standards, take action immediately:
- Disinfect the Well: Shock chlorination can eliminate bacterial contamination.
- Install Filtration Systems: Choose a system designed to target specific contaminants, such as a reverse osmosis filter for heavy metals.
- Retest the Water: After remediation, retest to confirm that the issue has been resolved.
Conclusion
Interpreting well water test results doesn’t have to be complicated. By understanding the key parameters and knowing what action to take, you can ensure safe drinking water for your household.
