Private Well? When Was Your Water Last Tested?

January/February 2015

Riverwoods Preservation Council

When was the last time you had your well water tested? In Lake Country approximately 90,000 residents rely on groundwater from aquifers to supply their private wells. The Lake County Health Department recommends that users of private wells have their well-water tested annually to assess whether the quality meets the minimum drinking water standards. Testing is not difficult and the Lake County Health Department reduces their processing fees considerably during National Ground Water Awareness Week, March 8 - 14. The basic test includes evaluating the water for bacteria and nitrates.

Obtaining a testing kit – There are three ways in which you may obtain a testing kit.

The first two options require you to return the water samples in person to the facility.

1) You may pick up the kit in person from the Lake County Central Permit Facility, which is located at 500 W. Winchester Road in Libertyville. The hours are Monday – Thursday, 7:30am – 3:30pm.

2) You may request that a kit be mailed to you by calling the Facility at 847-377-8020. However, there will be an additional charge for this option and these kits will still need to be returned in person during business hours.

3) You may request that staff from the Health Department come to your home to test the water for you. Under this option the staff will also inspect the well. This is the most expensive option and in past years the cost has ranged from between $52.00 to $55.00.

What is the basic cost for testing the water? During the past four years the Health Department has charged $16.00 for routine testing, but during National Ground Water Awareness Week, the Department has reduced the charge to $10.00 for well owners.

Although the official testing fees for 2015 had not been published by the deadline of this issue of the Village Voice, the Health Department staff expects the pricing structure to be similar as in the past years.

How long does it take to get results? Results of water samples are ready for homeowners in approximately three working days.
