Water Sample Sheets


Choose a faucet with a separate cold-water lever. (If only a single lever faucet is available - set the lever to the cold side and do not adjust once running.) If faucet is equipped with a strainer or aerator, remove it and any rubber washers before collecting the sample. Wipe inside of the threaded faucet with alcohol or chlorine bleach, on a Q-tip to clear any debris that could drop into the bottle. Allow the cold water to run a minimum of five minutes to clear the pipes. Carefully remove the red plastic tab from the sample bottle and discard plastic seal. Do not touch inner surfaces of cap or mouth of bottle. Collect sample, fill the sample bottle. Replace cap. Do not take sample directly from well or spring.

Failure to follow directions may result in unsatisfactory sample results.
Take the sample in the morning and deliver it to the office with payment before 1:00 PM Monday - Friday (except holidays).

Coliform Bacteria: The organisms in the total coliform group are called indicator organisms. That is, if present, they indicate that there is a possibility, but not a certainty, that disease organisms may also be present in the water.

E. Coli Bacteria: Escherichia Coli (e-coli). This is a specific species (subgroup) within the coliform family. They originate only in the intestines of animals and humans. Like fecal coliform they have a relatively short life span compared to more general coliform. Their presence indicates a strong likelihood that human or animal wastes are entering the water system.
