| Collecting a Water Sample |
View
Form |
All tests submitted must be collected in a container approved by the testing laboratory.
Collect the sample from an outside faucet, not a kitchen or bathroom faucet, if possible.
Make sure the faucet is above ground and free of grass, shrubbery, and debris.
Flush the faucet for several minutes.
Check the chlorine residual and enter it on the form if the sample is from a chlorinated water source.
Heat the faucet with a torch or wash it with a strong bleach solution to kill any bacteria that might be present. Heating the faucet is the preferred method.
Do not rinse the bottle or pour out the white powder. It is present to neutralize the chlorine residual so it does not interfere with the test.
Adjust the stream of water to the size of a pencil.
Without touching the inner neck of the bottle or lid, fill it to the 100 mL mark. Do not overfill or underfill the bottle.
Keep the sample out of direct sunlight and as cool as possible until taking it to the lab.
Paper Work For the Water Sample
Samples must be accompanied by a completed Water Bacteriology Form.
Enter the system name and ID number (public systems only).
Fill out the return address portion of the form for where the results are to be sent.

Enter the point of collection (site, location, or town) and county.
Enter the name and phone number of the collector.
Indicate what type of system the sample represents.
Enter the well depth and chlorine residual if they apply.

Return the sample to the lab within 24 hours of collection, but sooner if possible.
The fifteen dollar per sample fee is due upon submitting the sample.
The lab has ultimate authority to reject any sample due to incorrect sampling procedures, forms filled out improperly, samples too old for analysis, or other circumstances.
In the event that a sample is invalidated, a repeat sample will be requested. *A fifteen dollar credit will be given only if the sample was not set up for analysis.
When repeat sampling is required due to a positive result, the repeat testing will cost the standard fifteen dollars per sample fee.
Results will be mailed to the submitting party on the day following testing. Requests to have test results faxed or picked up should be made when samples are brought to the lab.
