Ready to Schedule?

  • Call, text or email to schedule an appointment. I’m happy to answer any questions.

  • Water samples can typically be collected within a few days.

  • Lab turnaround time varies with 1-2 weeks being standard.

  • It’s best to schedule a few weeks prior to when the sample report is required. This allows time to perform the necessary treatments to ensure a clean water record.
