3 WATER SAMPLING EXECUTIVE SUMMARY Pekron Consulting, Inc. performed water sampling for the Keeneyville School District 20 at the Early Childhood Center located at 5212 Arlington Circle in Hanover Park, Illinois. The purpose of the sampling was to identify potential lead contamination in the schools drinking water. The State of Illinois requires schools and day care centers to test for lead in water used for drinking and cooking. Mr. Kevin Brady, Industrial Hygienist, conducted the evaluation on October 27, 2017, under the supervision of Mr. Phillip G. Pekron, CIH, CSP. Analytical results indicate that none of the water source samples collected contained detectible levels for lead. All of the samples collected were below the EPA s action level for lead which is set at 15µg/L. The analytical results indicate that all the water sources contained levels of lead that were below the Illinois Department of Public Health s (IDPH) requirements for levels of lead in drinking water of 5 ppb. The water fountain located in Room 104 was not operational at the time of the sampling. Pekron recommends that this source be sampled after servicing and prior to use.

4 WATER SAMPLING 1.0 INTRODUCTION Pekron Consulting, Inc. performed water sampling for the Keeneyville School District 20 at the Early Childhood Center located at 5212 Arlington Circle in Hanover Park, Illinois. The purpose of the sampling was to identify potential lead contamination in the schools drinking water. The State of Illinois requires schools and day care centers to test for lead in water used for drinking and cooking. Mr. Kevin Brady, Industrial Hygienist, conducted the evaluation on October 27, 2017, under the supervision of Mr. Phillip G. Pekron, CIH, CSP. 2.0 BACKGROUND The U.S. EPA has set national limits for hundreds of contaminants including lead in drinking water and specifies various treatments that water systems must use to remove these contaminants. Through the Safe Drinking Water Act (SDWA) of 1974, the EPA has limited the quantity of pollutants allowed in drinking water. Contaminants include microorganisms, metals, organic compounds, inorganic compounds, pesticides or herbicides, and radionuclides. As water travels over the surface of the land or through the ground, it can acquire naturally occurring mineral and can pick up substances resulting from the presence of animals or from human activity. Corrosion of plumbing systems can also affect the purity of drinking water. The U.S. EPA also sets Secondary Drinking Water Regulations which may cause cosmetic effects (skin and tooth discoloration) or aesthetic effects (such as taste or odor). Providing safe drinking water to children is required by various agencies. Lead can cause a range of health issues including behavioral problems and learning disabilities, especially in young children. Routine testing of public drinking water detects if the water provided by the city is safe up to the building. However, lead can exist in old pipes and plumbing fixtures within the school. The State of Illinois has mandated the following schools and daycare centers test their water for lead. 1. Daycare facilities including group daycare centers and in-home daycare centers built before January 1, 2000, and that serve children under the age of six. 2. Public and private schools built before January 1, 2000, and occupied by ten or more students pre-kindergarten through grade five. 3.0 MONITORING AND ANALYTICAL METHODOLOGY Each facility is required to collect samples from every water source including taps, faucets, drinking fountains, and wash basins that could be used for drinking or preparation of food. This includes all classrooms, science labs, halls, cafeterias, kitchens, lounges, offices, gyms, locker rooms, athletic fields, etc. Bathroom sinks and janitorial wash basins are excluded. A first draw sample was obtained from each source after the water has been standing for 8-18 hours. School district personnel flushed each source the day prior to sampling to insure this requirement was met. A second flush sample was collected after running the water for 30 seconds. Samples were analyzed using a USEPA approved drinking water method by a certified drinking water lab (Appendix C). Early Childhood Center October, 2017 Hanover Park, Illinois 1

5 WATER SAMPLING Lead drinking water samples were collected using sterile plastic liter bottles. While filling, the bottle was tilted at an angle to allow the water to run down the inside of the container. When filled, the cap was secured and a label was affixed to the container. Care was taken not to overfill the container. Drinking water samples were delivered to an EPA accredited laboratory where they were analyzed according to method (Appendix C) 4.0 RESULTS/CONCLUSION Analytical results indicate that none of the water source samples collected contained detectible levels for lead. All of the samples collected were below the EPA s action level for lead which is set at 15µg/L. The analytical results indicate that all the water sources contained levels of lead that were below the Illinois Department of Public Health s (IDPH) requirements for levels of lead in drinking water of 5 ppb. The water fountain located in Room 104 was not operational at the time of the sampling. Pekron recommends that this source be sampled after servicing and prior to use. 5.0 REPORTING REQUIREMENTS The Illinois Department of Public Health (IDPH) has set forth the following reporting requirements: 1. Within 7 business days of receipt of test results, schools must all results to IDPH at DPH.LeadH2O@illinois.gov. 2. If all sample results are less than 5ppb, schools may use their website (at a minimum) to notify parents of the results. 3. If any sample result exceeds 5ppb, schools must notify parents in writing or electronically, and include: a. The location and source exceeding 5ppb, and b. The USEPA website for information about lead in drinking water; Kevin Brady, Industrial Hygienist November, 2017 Date Phillip G.
