The plastic bottles have been pre-sterilized for the bacterial tests. We strongly advise that you use one of our bottles as we cannot guarantee the sterility of your home containers. Do not open the bottle prior to collecting the water samples in order to reduce the chance of accidental contamination. The small, plastic bottles with the red seal contain white crystals, a de-chlorinating agent and should not be emptied out. The large bottles may contain sterile condensation.
Inspect the outside of the faucet. If water leaks around the outside, select a different faucet.
Remove all attachments (aerators, etc.) from the faucet.
Use household bleach on a paper towel and swab around the head of the faucet, inside and out.
Turn on the coldwater tap and let the water run for five minutes to permit clearing of the lines.
Turn down the flow of water until the stream reaches the thickness of a pencil.
If the bottle has a seal on it, remove the seal then carefully remove the cap from the STERILE bottle. Be sure that you do not touch the inside of the cap or the outside rim of this bottle. Fill the bottle to within one inch of its rim (100ml). DO NOT RINSE this bottle out. The white crystals are sodium thiosulfate which bind to any residual chlorine in the water sample. Replace the cap and tighten it so that the cap will not leak. If it is a large bottle, fill the bottle to within one inch of the rim.
