Open the faucet and adjust flow to avoid splashing of water. Place the container lid facing up to prevent contamination and collect water in the container provided up to the neck of the bottle (1000mLs).


Close the bottle and record the date, time, and location of sampling on the label provided along with the initials of the sample collector.
