Sampling Procedure
for Bacteria

Requires A Sterile Bottle

  1. Locate a sample tap near the well, preferably not a swing, leaky or outside faucet. Remove any screens and aerators.
  2. Choose a metal faucet that can be sterilized properly. Sterilize the metal tip of the faucet by heating with a torch or flame. Do not flame faucet if there are plastic internal parts.
  3. If metal faucet is not available, sterilize the tip of a plastic faucet with 95% ethyl alcohol.
  4. Let water run for 2 minutes. Reduce the flow to a pencil width. Let water run for 2 more minutes.
  5. Remove the cap from the sample bottle without touching the rim of the bottle or inside of the cap. Place cap on a clean surface, such as a clean paper towel.
  6. Fill bottle up to the line. Avoid splashing.
  7. Return sample to U.S. Water within 30 hours.

Sample Records Will Be Maintained for 5 Years Before Disposal
