- A water sample MUST be taken in a sterile container provided by the laboratory.
- Do not touch the inside of the jar or lid because they are sterile.
- Collect the sample from a point as close to the well as possible. (For best results do not collect a water sample from a point after a water softener.)
- If the faucet used has an aerator on it, remove the aerator before taking the sample.
- Bacteria are sometimes present on the rim of the faucet. To sterilize the faucet prior to sampling, light a book of matches to "torch" the faucet. Or you may heat it with a propane torch a few seconds, being careful not to damage the faucet.
- Turn on the water and let it run for a minimum of five (5) minutes before collecting the water sample
- Open the bottle and place it under the slowly flowing water stream. Fill the bottle to within ½ inch of the top of the bottle. Cap the bottle tightly and record the Sample Collection Time/Date on the Information Sheet.
- Deliver the sample and the completed Information Sheet form to AgSource Laboratories as soon as possible. Call ahead for hours and drop-off information. Inaccurate results may occur if samples are delayed. Samples held for over 24 hours may be rejected for analysis.
