Water Testing Kits

Home test kits are useful for screening and ongoing monitoring, but health-based decisions should rely on a state-certified laboratory.

What to look for

  • The specific parameters you need (e.g., bacteria, nitrate, hardness, pH)
  • Clear instructions and reasonable accuracy for screening
  • For health decisions, a mail-in certified-lab option

Limitations

  • Home kits are generally less accurate than certified-lab analysis.
  • A positive or borderline health-based screening result should be confirmed by a certified lab.
