HAZARDS TO GROUNDWATER
IN AND AROUND THE HOME

Many toxic substances are stored and used in and around the home. Examples include used and unused motor oil, antifreeze, other automotive fluids, pesticides, cleaning solutions, etc. If not handled and disposed of properly, these toxic substances can contaminate groundwater.

The best groundwater protection is prevention against contamination. Do not apply pesticides or dispose of household chemicals and toxic substances in the vicinity of a water well. Always follow the manufacturer's instructions when using chemicals such as pesticides. Do not buy more than you need and use only the amount necessary.

Improperly discarded household chemicals and toxic substances can contaminate groundwater via the natural movement of water through infiltration into the soil and gradual movement to an aquifer. Shallow aquifers are most vulnerable to such contamination. Disposal of unwanted household chemicals or toxic substances into an abandoned well can contaminate the aquifer directly and affect nearby water wells. Thus, abandoned wells are potential routes of groundwater contamination and must be sealed in accordance with the Illinois Water Well Construction Code.

Information pertaining to proper disposal of household chemicals and toxic substances can be obtained from the Illinois Department of Energy and Natural Resources at telephone 217/333-8940.

Proper well location and construction are also important to prevent contamination of water wells from improper disposal or handling of household chemicals and toxic substances. A well should be located where good drainage exists and where the well is higher than the surrounding ground. All sources of contamination should be located at a lower elevation than the well, and the distance between a water well and a particular source of contamination should equal or exceed the minimum specified in the Illinois Water Well Construction Code. Proper well construction includes grouting or sealing of the annular space between the drill hole and the well casing to prevent contaminated surface water from entering the well.

In summary, groundwater contamination from household chemicals and toxic substances can be prevented by proper use, storage and disposal of these chemicals/substances and by assuring that water wells are properly located and constructed.
