After Installation

Once you have installed your water well you need to have the well inspected and a satisfactory water sample needs to be obtained before final approval is given. When you are ready to have the water well inspected you can contact the LCHD to set up an appointment. Inspection appointments can be scheduled at our Lake County Central Permit Facility between the hours of 7:30 a.m. - 4:30 p.m. Monday through Friday (847-377-8020). When it is time to have your water supply sampled, you can have the sample collected either by your water well contractor, a private licensed sanitarian or LCHD staff. If the Department collects the sample, a nominal fee will be charged. Samples can be brought into our facility Monday - Thursday between the hours of 7:30 a.m. -3:30 p.m. The results of your water analysis (coliform bacteria/nitrate/nitrite) may be obtained from the Department in approximately 3 working days.

Note: Before a water sample can be collected, the chlorine that the water well contractor adds to the well to disinfect it after its construction must be removed by running the water (flushing). If your residence is serviced by a septic system, the Department recommends when you flush the chlorine from your well and plumbing using an outside spigot. This can be accomplished by attaching a garden hose and discharging the water away from your septic system. After there is no longer a detectable chlorine odor, run all faucets in the house until they are also flushed free of the chlorine. Since the sense of smell is not an accurate indication that chlorine is present, we recommend the use of a chlorine test kit.

Water Sample
Once these field tests have been conducted, and the absence of chlorine has been confirmed, the sanitarian will collect a water sample from any permanently installed inside fixture. This fixture could be a sink or a permanently installed threadless faucet near the pressure tank that is at least 18 inches above the floor. The LCHD laboratory analyzes the sample for the presence of total coliform and E coli bacteria. A nitrate/nitrite analysis will also be performed.

If the water analysis is satisfactory, (no coliform bacteria present and nitrates at or below 10 milligrams per liter and nitrites are at or below 1 milligram per liter), the water well will be approved for human consumption.

Note: No one should use the water for drinking, bathing, washing dishes and all skin contact should be avoided until it has been tested and approved.
