1 WATER QUALITY TESTING FOR SCHAUMBURG COMMUNITY CONSOLIDATED SCHOOL DISTRICT 54 MEAD SCHAUMBURG, ILLINOIS JULY 13, 2016 PROJECT NUMBER: Hubbard Ave., Batavia, IL 60510,

2 Schaumburg Community Consolidated School District 54 Mead Water Quality Testing Project: E&E EXECUTIVE SUMMARY Water quality testing was conducted at Mead School on July 13, Although not required at the time of sampling, the testing is recommended by the EPA to prevent the health effects of lead exposure and maximize the learning environment. Schaumburg Community Consolidated School District 54 performed this testing as a pro-active measure to prevent the health effects associated with lead exposure and maximize the learning environment. Lead sample results at drinking water sources ranged from non-detectable (< 2 ppb) to 2.79 ppb. All results are below EPA action levels and indicate water quality is acceptable for lead content. Incoming flush water samples were below EPA action levels for lead, copper and ph. When water sits in piping and fixtures for a prolong time period leaching, there is a higher potential to leach contaminants. For this reason, drinking water sources should be flushed after long periods of non-use, like summer breaks, before occupants can access sources. July 2016

4 Schaumburg Community Consolidated School District 54 Mead Water Quality Testing Project: E&E INTRODUCTION Schaumburg Community Consolidated School District 54 implemented a proactive program of water testing in all schools. On the date of the sampling this testing was not required for schools that are on a Public Water Supply System which is the case for Schaumburg schools. The testing is recommended by the EPA to prevent the health effects of lead exposure and maximize the learning environment. The Lead in Drinking Water Testing Bill (LDWTB) was signed into law by Governor Bruce Rauner effective January 17, The bill amends six (6) different Illinois Codes and Acts including: The Illinois School Code Illinois Plumbing License Law. The act requires School buildings constructed prior to January 1, 2000 to conduct testing of drinking water sources for lead and provide written notification of the results. Through a waiver provision results in this report may be accepted by IDPH as fulfilling the LDWTB testing requirement. Testing at Mead School was conducted on July 13, 2016 by Hazel Carnero of Aires Consulting. The survey design and report was completed by Geoffrey J. Bacci II, PE. BACKGROUND INFORMATION Lead most frequently gets into drinking water by leaching from plumbing materials and fixtures as water moves through a school s distribution system. Even though the drinking water you receive from your water supplier meets federal and state standards for lead and copper, your facility may have elevated lead levels due to plumbing materials and water use patterns. Leaching can occur for several reasons but the most significant is corrosion which can occur if water is acidic. Acidic water has a ph less than 7.0. Lead in new plumbing and plumbing repairs was banned in This ban did not entirely eliminate lead as 0.2% lead is still allowed in solder and 8% lead is allowed in Page 1 July 2016

5 Schaumburg Community Consolidated School District 54 Mead Water Quality Testing Project: E&E piping systems. Pre-1986 plumbing systems have a higher potential to leach lead into drinking water. 100% of Schaumburg water is supplied from Lake Michigan. The water is delivered through Chicago s Jardine Water Purification Plant and South Water Purification Plant. Water testing of the supply water is conducted by Schaumburg as required by the EPA. Testing reports indicate that lead and copper are below action levels and in accordance with EPA safe drinking water standards. Lead is a toxic metal that is harmful to human health. Young children, those 6 years and younger, are at particular risk for lead exposure because they have frequent handto-mouth activity and absorb lead more easily than do adults. Children s nervous systems are still undergoing development and thus are more susceptible to the effects of toxic agents. Lead is also harmful to the developing fetuses of pregnant women. METHODOLOGY Water testing followed protocol recommended by the EPA in the following publication: 3Ts for Reducing Lead in Drinking Water in Schools: Revised Technical Guidance: Environmental Protection Agency (EPA): October 2006 Version This lead testing protocol is different than the protocol used by public water system for testing. The Sample size is 250 milliliter as opposed to a 1 liter sample. A smaller sample is more effective at identifying the sources of lead because it represents a smaller section of plumbing. A smaller sample is also more representative of water per serving consumed by a child. All water source samples are first draw samples. Water collection occurred after sources were unused for at least eight (8) hours. The following source locations were sampled: Drinking fountains, both bubbler and water cooler style. (labeled WF) Sink used for daycare, if applicable. (labeled DS) Two (2) classroom sinks in different locations. (labeled CS). Page 2 July 2016

6 Schaumburg Community Consolidated School District 54 Mead Water Quality Testing Project: E&E One sample (labeled IF) was collected after water was flushed from a source closed to incoming water. This sample was a test of the water received from the city supply. IF samples were tested for lead, copper and ph. The EPA recommends the following standards to evaluate water testing results: Lead: 20 parts per billion (ppb) Copper: 1300 ppb ph: 7.0 or higher. Public water supplies are required by the Safe Drinking Water Act to take corrective action if 10% or more of their sources contain lead levels greater than 15 ppb. The LDWTB expands these recommendations to require parent notification when lead results exceed 5 ppb for any covered drinking water source. The Bill also directs the Illinois department of Public Health to draft rules by 1/1/2018 which may have additional requirements. After collection, samples were transported in a cooler with an ice pack. Samples were analyzed by Prairie Analytical Systems, Inc. Prairie Analytical is accredited by the National Environmental Laboratory Environmental Conference (NELAC). RESULTS Appendix I includes a list of sampling locations and a location Map. Appendix II contains the laboratory results. Lead sample results at drinking water sources ranged from non-detectable (< 2 ppb) to 2.79 ppb. All results are below EPA action levels and indicate water quality is acceptable for lead content. Incoming flush water samples were below EPA action levels for lead, copper and ph. When water sits in piping and fixtures for a prolong time period leaching, there is a higher potential to leach contaminants. For this reason, drinking water sources should be flushed after long periods of non-use, like summer breaks, before occupants can access sources. Page 3 July 2016

7 Schaumburg Community Consolidated School District 54 Mead Water Quality Testing Project: E&E According to the LDWTB, results of samples that are 5 ppb or less should at minimum be posted on the District s website. PROFESSIONAL CERTIFICATION Aires Consulting, a division of Gallagher Bassett Services, Inc. conducted this study in the interest of Schaumburg District 54 to assist in meeting environmental obligations and regulations. In this respect, we hope the results of this study are useful. This study was not intended to include every environmental exposure that may be present at the facility; only those items specifically addressed in the report were evaluated. If you have any questions concerning this study please let us know. Respectfully Submitted, Geoffrey J. Bacci, II, PE Director Operations Page 4 July 2016
