Potable Water / Wells
OVERVIEW/GENERAL INFORMATION
The general goal of the Private Water Program is to protect
the public health by assuring private water wells and pumps are installed to
provide safe drinking water through the administration and enforcement of the
Water Well and Pump Installation Contractor’s Licensing Act, Water Well
Construction Code Law, and the Water Well Pump Installation Code Law.
BCHD achieves these program goals by issuing water well
construction permits, inspecting new water well construction, investigating
complaints regarding private and semi-private water supplies, conducting field
evaluations, and performing other investigations such as sanitary water supply
surveys for real estate property transfer inspections.
WELL PERMITS AND FEES
Fees are paid for at the time of application/plan
submittal. For new construction, an
approved site plan is on file at the Health Dept. This site plan designates a pre-approved well
area and well drillers only need to turn in their application and fee for new
construction. For replacement wells, a
scaled drawing of the well placement on the lot needs to be submitted along
with the well application and fee. A
permit to construct or deepen a water well must be obtained from Boone County
Department of Public Health prior to construction. Boone County Department of Public Health must
be notified 48 hours prior to commencement of work.
To acquire the Illinois State Well Permit Application form
and the Illinois Water Well Construction Report go to the IDPH web site: http://www.idph.state.il.us . You can
find these forms by pressing the publications tab and follow the link to “W”.
WELL SEALING
The owner of a water well, boring, or monitoring well shall
assure that such well is sealed within 30 days after it is abandoned and when
the well is no longer used to supply water or is in such a state of disrepair
that the well or boring has the potential for transmitting contaminants into an
aquifer or otherwise threatens the public health or safety. Water wells shall be sealed by a licensed
water well driller pursuant to the Water Well and Pump Installation
Contractor’s License Act. An individual
who is not so licensed may seal a well, provided the well is located on land
which is owned or leased by such individual and is used by such individual for
farming purposes or is such individual’s place of abode and provided a request
is made to the local health department prior to the commencement of sealing
indicating how the water well is to be sealed and the materials to be
used. Note: all homeowner well sealings are inspected by
Boone County Department of Public Health.
You may acquire the State Water Well Sealing Form at the following
site: www.idph.state.il.us. You can find this form by pressing the publications
tab and follow the link to “W”.

WELL SAMPLING
NEW WELLS: Illinois Department of Public Health requires
that all new wells be tested to assure the water supply is safe. In Boone
County, the plumbing inspector tags
faucets reminding new homeowners to call Boone County Department of Public
Health prior to consumption of the well water.
Also, letters are sent to new homeowners when the well driller sends his
Construction Report to the Health Department and again when the Health Dept
receives an Occupancy Permit. An
appointment is made with the new homeowner and education is offered regarding
their well and septic. The new homeowner
is given copies of their septic layout and well construction report. A water analysis is sent to the new homeowner
and if it is satisfactory they may consume their well water. If the analysis is unsatisfactory, a
chlorination procedure is sent to the homeowner and the homeowner must retest
until their well water is satisfactory.
(fee for retesting)
PRIVATE WATER WELL
SAMPLING: The Illinois Department of
Public Health recommends that a water sample be taken annually to assure that
the water source remains free of bacterial contamination. Bacteria and parasites that cause illness can
enter a well in many ways. Whether the
contamination comes from the materials and tools used in the well’s construction,
from septic failures near the well or from feedlot runoff, the bacteria and
parasites must be destroyed to ensure safe water.
Customers are advised to pick up a sterile bottle and
procedure at Boone County Department of Public Health. Different bottles/fees and the dates for
sampling are available at the time you stop in for the procedure. Following is a list of water tests available
at Boone County Department of Public Health.
The standard test includes Coliform Bacteria and Nitrates. Also, you may test for Iron, Hardness,
Sulfate, Fluoride, Chloride, pH, Specific Conductivity, Lead and Copper. A special appointment is needed for surface
sampling. If you have any questions regarding your well
or well water quality, please call the Environmental Division of Boone County
Health Department. (815-544-2951 ext 2).

including Coliform Bacteria, Nitrate, Iron, Hardness, Sulfates,
Flouride, Chloride, and Water Odors, click here.
CHLORINATION OF WELL WATER: If your well water tests positive for
coliform bacteria or excessive amounts of other types of bacteria, this is an
indication that you need to chlorinate your well. Resampling is required by Boone County
Health Department. If the well is
contaminated, it could compromise the aquifer which serves neighboring wells,
therefore making it a public health issue.
Chlorination can be done by the property owner or any well driller, well
pump installer or other experienced contractors. Usually after chlorination, the well samples
are acceptable. The water should,
however, be sampled annually to properly monitor the condition of the
well.

WELL PITS
The Illinois Water Well Construction Code prohibits
constructing new wells in pits. Many
existing wells, however, are located in pits.
These wells and pits should be examined closely to determine if they
meet the following requirements:
1) The well pit is structurally sound and
watertight.
2) The
well casing extends at least 12”
above the pit or basement floor.
3) The
well has a well seal to prevent
contaminants from entering the well.
4) The well pit has a watertight manhole
and cover.
If any of these requirements is not met, the well pit is not
compliant with State Code and may present a (public) health threat. If a pit floods, the wellhead may become
submerged and the well could become contaminated.
If the well pit and wellhead are in good condition, check
them regularly to make sure the pit is free of debris and is not wet or
flooded.
FAQ’s (FREQUENTLY ASKED QUESTIONS)
How do I know if my
well water is safe to drink?
Have your water tested for the presence of coliform bacteria
and nitrates. The standard for coliform
bacteria in well water is zero. High
quality drinking water will also have zero or low levels of non-coliform
(“atypical”) bacteria.
The State standard for nitrate is 10 milligrams per liter
(10 mg/l) as N (nitrogen). Levels higher
than this may be unsafe for pregnant and nursing women and children under 6
months old.
What are
contaminants?
Contaminants include metals, chemicals, bacteria, parasites,
other micro-organisms and solids, such as sand, that may be found in well
water. Not all contaminants pose a
health risk. Many contaminants are
naturally occurring and are acceptable at low levels. The EPA’s National Primary Drinking Water Regulations (NPDWRs or primary standards)
protect public health by limiting the levels of contaminants in drinking
water. For more information, visit the
EPA website at www.epa.gov/safewater/contaminants/index.html#mcls
How do contaminants
get into my well?
Contaminants can enter a well through an opening in the well
cap, a crack in the well casing, through the groundwater, or by back-siphoning
from plumbing fixtures. If you notice
any damage to the casing, cap or electrical conduit, get it repaired as soon as
possible. Make sure that all plumbing
fixtures, drains, and hoses are installed and maintained correctly to prevent
back-siphoning of water into the potable water system. Geologic formations and direction of
groundwater flow also influence the possibilities of contamination being transmitted
into the well water from a particular source.
Contamination of a well can also occur during well
construction or when a well is serviced.
Any time a well is opened for service it should be chlorinated to
prevent bacterial contamination.
How do I dispose of old or unused medications to keep them out of the water supply?
Don't flush old or unused medications. This puts them
directly into the water supply (city water and private well water).
See our flyer below for a better disposal method. Also see
the link below to the Environmental Protection Agency for a diagram of
water contaminants and how they enter our water supply.

Where do nitrates
come from?
Sources of nitrogen and nitrates may include runoff or
seepage from fertilized agricultural lands, municipal and industrial waste
water, refuse dumps, animal feed lots, septic tanks and private sewage disposal
systems, urban drainage, and decaying plant debris. Soil characteristics also influence the
movement of nitrates into the groundwater.
For more information on nitrates in drinking water, visit the following
site: www.idph.state.il.us. You can find the information by pressing the
“a-z topics” tab and follow the link to “N”.
How can I get rid of
the nitrates in my well water?
Boiling does not remove nitrates – it makes the
concentration higher. Reverse osmosis
treatment units, installed in the home, may reduce the level of nitrates in
well water.
How can I disguise or
landscape around my well?
You should not bury your well. The Illinois Water Well
Construction Code
requires 8” of clearance between the top of ground level and the
well cap. This should be accomplished without creating
a bowl or depression around the well. The area immediately around
the well needs to be kept open and free of litter,
debris, and plants. Flower beds and
shrubbery near the well should still allow easy access to the well for
maintenance and should also allow enough room for the well to
“breathe”. If you put a decorative item such as a
wooden
wishing well over your water well, make sure to clean it out regularly
to prevent
buildup of debris.
How often should I
sample my well water?
The Illinois Department of Public Health requires that all
new wells be tested to assure the water supply is safe. After the initial test, sampling is
recommended annually and after the well has undergone repairs.
How do I take a water
sample?
Water samples must be collected in sterile bottles, which
are available at the Health Department. Choose the faucet or
spigot closest to where the water supply line
enters the house, preferably bypassing any water treatment devices.
Remove any
aerators from the faucet. Open the
faucet and allow the water to run for 2-3 minutes to flush out the
line. Shut the water off and clean the faucet thoroughly
with alcohol (wipes are available at the Health Department). Turn
the faucet on again, making sure the
water flows out in a steady stream. Open
the sterile bottle, being careful not to touch the inside of the bottle
or the
lid. Grabbing the bottle by the bottom,
hold it under the flowing water and fill it to the top line.
Carefully screw the lid on tightly. Make note of the time the
sample was
collected and which faucet you used. Keep the sample on ice or in
the refrigerator until it is taken to the
Health Department or lab. (These
instructions apply to the standard test for coliform bacteria and
nitrates. Other tests may require
slightly different methods. Check with
the Health Department or the lab for instructions.)
You may also arrange to have an inspector come and collect
the sample. Call the Environmental
Office for fees and to make an appointment at (815) 544-2951, Ext. 2.
When can I
take/submit a water sample?
Call the Environmental Office to confirm sampling
dates. Water samples must be collected
after 8:00AM and brought into BCHD
before 4:30PM on a sample collection
day.
