Lead Service Inspection

In January 2017, the Illinois Environmental Protection Agency amended the Illinois Environmental Protection Act (415 ILCS 5/et seq) to include a mandate for operators of community water systems in the State of Illinois to create a comprehensive water service line inventory. This inventory must account for the total number of service lines in the system, the number of lead service lines in the system, and the number of lead service lines replaced the previous year. 

The Village is requesting that all residents who receive a letter schedule an appointment for a plumbing inspection that will be conducted by Public Works staff members. This inspection will require entry into the home to determine the material of the water service. The appointments are scheduled in half-hour increments, but should only take approximately 5 minutes. 

To schedule an appointment residents can call 847-870-5640 or Schedule Appointment

There is no cost for the inspection. 

We appreciate everyone’s cooperation in the Villages efforts to comply with the Illinois Environmental Protections Agency’s requirements. If you have any questions about the lead water service inventory program, please contact the Public Works Department at 847-870-5640 or publicworksdept@mountprospect.org

Lead is a common naturally occurring metallic element that can be found in air, soil, and water. It is also a powerful toxin that is harmful to human health. Lead was commonly used in gasoline and paint until the 1970s and is still sometimes found in products such as ceramics, batteries, ammunition, and cosmetics. Lead was used for centuries in plumbing because of its pliability and resistance to leaks; in fact, lead’s chemical symbol, Pb, is derived from the Latin word for plumbing. In 1986, U.S. Congress amended the Safe Drinking Water Act to prohibit the use of pipes, solder, or flux that were not “lead free.” At the time “lead free” was defined as solder and flux with no more than .2% lead and pipes with no more than 8%. In 2014, the maximum allowable lead content was reduced from not more than 8% to not more than a weighted average of 0.25% of the wetted surface of pipes, pipe fittings, plumbing fittings, and fixtures.

Lead is a toxic metal that can cause immediate health effects at high doses and long-term health effects if it builds up in the body over many years. Lead can cause brain and kidney damage in addition to effects on the blood and vitamin D metabolism. Pregnant women and young children are particularly vulnerable because the physical and behavioral effects of lead occur at lower exposure levels in children than in adults. In children, low levels of exposure have been linked to central and peripheral nervous system damage, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells. While people are more commonly exposed to lead through paint, soil, and dust, U.S. EPA estimates infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water.

Because it is colorless and tasteless, lead is not readily apparent in water. In fact, the only way to know for certain whether your drinking water contains lead is to have your water tested by a certified laboratory.

Lead is almost never present when water flows from the treatment facility, nor is it present in the water mains running beneath the streets. However, in some older homes lead may be present in the pipe connecting the home to the water system – known as a service line. Lead in service pipes, plumbing, or fixtures can dissolve, or particles can break off into water and end up at the tap.

Lead can be harmful even at very low levels and can accumulate in our bodies over time, so wherever possible, steps should be taken to reduce or eliminate your household’s exposure. While risks vary based on individual circumstances and the amount of water consumed, no concentration of lead is considered “safe.” Households with pregnant women, infants, or young children are most vulnerable to the harmful effects of lead at low levels.

The best way to remove risks of lead in water is to completely replace all sources of lead. But there are also steps you can take right away to reduce lead levels in your water.

1. Run the Tap Before Use – Lead levels are likely at their highest when water has been sitting in the pipe for several hours. Clear this water from your pipes by running the cold water for 3-5 minutes before using. This allows you to draw fresh water from the main. In efforts to conserve water, you can use this water on house plants or to flush toilets.
2. Clean Aerators – Aerators are small attachments at the tips of faucets which regulate the flow of water. They can accumulate small particles of lead in their screens. It’s a good idea to remove your aerators at least monthly and clean them out.
3. Use Cold Water for Cooking and Drinking – Always cook and prepare baby formula with cold water, because hot water dissolves lead more quickly, resulting in higher levels in water.
4. Filter the Water – Many home water filters are effective at removing lead. If you purchase a filter, make sure it is certified for lead removal and that you maintain it properly. Find out more on filter certification at www.nsf.org.

Households with pregnant women, infants, or young children should be especially aware of the potential for lead exposure through drinking water. If you suspect there may be lead in your home plumbing, consider having your water tested. The City regularly tests for lead in the drinking water at a selected number of service locations. If lead is detected, consider purchasing a filter certified for lead removal or using an alternate source of water until the problem is corrected. Babies and young children are most vulnerable to the harmful effects of lead at low levels. U.S. EPA estimates infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water.

Because lead is not absorbed through the skin, bathing or showering in water containing lead is not considered a health risk.

You can contact the Village of Mount Prospect Public Works Department to inspect both your service line. Please call 847-870-5640 or visit www.mountprospect.org to schedule an appointment.

No. If you purchase a water filter or home treatment device, make sure it is independently certified for lead removal and that you maintain it properly. Find out more on filter certification at www.nsf.org.

Lead can impact animals the same way it does humans. Because domestic animals consume a relatively high volume of water relative to their body weight, pet owners with lead in their home plumbing may want to take precautions.

No. In fact, lead in drinking water generally represents only about 20% of total exposure, according to the U.S. Centers for Disease Control and Prevention. However, drinking water can account for more than half of lead exposure in children because of their lower body weight. Additionally, because no level of lead is considered safe, completely eliminating potential sources of lead is strongly advised.

Yes. The Village of Mount Prospect is required by the Illinois Environmental Protection Agency to test for lead every three years from IEPA approved homes. The most recent sampling period was during the summer of 2020 and the 90th percentile value was 3.79 ppb which meets EPA requirements of not being greater than 15 ppb.

Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available by calling the Safe Drinking Hotline at 1-800-426-4791 or by visiting www.epa.gov/safewater/lead.
