Quick Answer
Test your hand-dug well water at least once every 3 months, and after any heavy rainfall, changes in land use, or construction near the well. You should also test after installing a new well cap or if you notice any changes in the well's water quality.
Importance of Regular Testing
Testing your well water regularly is crucial to ensure it remains safe for drinking. Hand-dug wells are particularly susceptible to contamination due to their proximity to the water table and potential exposure to nearby surface activities. A well water test should be performed at least every 3 months, and after any significant changes in the surrounding environment.
Choosing the Right Tests
When testing your well water, select a comprehensive test package that includes parameters such as pH levels, total dissolved solids (TDS), nitrates, total coliform bacteria, and Escherichia coli (E. coli) bacteria. You may also want to consider testing for other contaminants like lead, arsenic, and volatile organic compounds (VOCs), depending on your local water quality concerns. Consider hiring a certified laboratory to perform the tests and provide accurate results.
Additional Considerations
In addition to regular testing, it is essential to maintain your well and its cap properly. This includes inspecting the well casing and cap for signs of damage or corrosion, ensuring the well is properly vented, and keeping the well area free from debris and potential sources of contamination. Keep a record of your test results and any maintenance performed on the well, and consider consulting with a well-drilling expert or water quality specialist if you have any concerns about your well’s water quality.
