Water Analysis

Water Sampling Techniques

Good water sampling techniques are crucial in order to obtain accurate test results.  Here are a few water sampling techniques to help you obtain that quality water sample.

  • Let your water source run for at least five minutes
  • For elemental analysis: open sample container and rinse three times, then fill bottle
  • For bacterial analysis: Open bottle and fill.  Do not rinse
  • Water samples must be submitted to the laboratory Monday through Thursday.  Samples should be submitted as soon as possible after sampling as some elements have short holding times
  • Sample containers are available at Soiltest
