• You should test well water at least once a year, but more frequently if you notice changes in taste, color, or smell.
  • Regular testing is essential because:
  • Bacteria and nitrates can enter the well from surface contamination, especially after heavy rain or flooding.
  • pH and mineral levels fluctuate over time, affecting plumbing and water quality.
  • Nearby construction or land use changes can introduce new contaminants.
  • Health risks: Contaminated water can cause stomach issues, neurological problems, or long-term health effects.
  • A basic annual test should check for bacteria, nitrates, pH, and minerals. More in-depth tests may be needed based on location and previous water quality results.
