Taking a Water Sample

  1. Get a proper water sample bottle from BSC Labs, sterile containers can also be obtained from drug stores, or you can boil a glass jar and lid for 10 minutes. Only water collected directly into these bottles will be accepted.
  2. Plan to sample your well water when you’re sure you can deliver it to the laboratory within 2 hours. Your water sample should not be left sitting for a long period of time as this can lead to inaccurate results.
  3. Remove any aerator, screen or other attachments from your faucet. Don’t take a sample from a garden hose. Take a sample from an inside tap with no aerator, such as the bathtub.
  4. Disinfect the end of the faucet spout with a match or lighter before running water to remove debris or bacteria. 
  5. Turn on cold water and let it run for three to four minutes to remove standing water from your plumbing system.
  6. Remove the sample bottle lid :

    • don’t touch the inside of the lid
    • don’t put the lid down
    • don’t rinse out the bottle.
  7. Fill the bottle to the level that is marked, as described in the enclosed instructions, and close the lid firmly.
  8. Keep the sample cool (but not frozen) until it’s returned to the drop-off location. Again, deliver the sample within 2 hours or it may not be processed. Remember that proper handling will help to make sure that your test results are accurate! Don’t store samples in warm places such as your car trunk.
  9. For a Chester County Complete, a sterile container and one non-sterile qt container are required.
