1. You can only take
bacterial samples on Mondays through Thursdays. There is only a
from the time you take the sample until the lab can test it, otherwise
the bacteria will die and will not be detected. We suggest taking the sample
in the morning and dropping it off at the Lincoln County Health Department
before 11:00 AM to give the lab as much time as possible to receive and
test the sample.
2. You need to disinfect where
you take the water sample. Remove aerator screen, if present. You can use
a spray bottle with a bleach and water solution (1 part bleach to 4 parts
water) and spray the entire area around the faucet as well as inside the
faucet. Then let the water run for two minutes to flush the line; take
the cap off of the water bottle and fill it up to the line on the bottle.
Do not fill the bottle above the full line as the lab will reject it due
to their automation process. Be careful not to touch inside the cap, as
this can contaminate your sample. Do not remove the powdery substance inside
the bottle, this removes any free chlorine in the water.
3. Fill out the red form with
your name and address. This address is where the results will be mailed.
You must also fill in the date you take the sample and the time. There
is also a number on the water bottle that you must mark on the form.

on the mailing label and seal the box with tape. Return the box(es) to
the Lincoln County Health Department by 11:00 AM on the same day as the
