Chicago Ridge School District 127.5 Water Quality Testing – Finley Junior High Project: 17-18292.ENV

INTRODUCTION Chicago Ridge School District 127.5 implemented a proactive program of water testing at Ridge Lawn Elementary School. Water sampling was conducted by Kathryn Hermann of Aires Consulting on September 30, 2017. Mr. Geoffrey J. Bacci II, P.E. designed the studied and developed this report. All sampling methodology followed protocol required by The Lead in Drinking Water Testing Bill (LDWTB) an guidelines published by the Illinois Department of Public Health (IDPH). Detailed background information on testing requirements, methodology and lead health effects are included in the main report to the District that summarizes results and offers recommendations. RESULTS Field sheets identifying sample numbers and sample locations maps are included in Appendix I. Laboratory results are included in Appendix II. The following locations exceeded 5 parts per billion (ppb). Locations that exceeded the EPA action level of 20 ppb are shown in bold print. •

FKS-4A: first draw sample from the left kitchen sink- 5.65 ppb

None of the sources exceeded the EPA action level of 20.0 ppb. Results should be at minimum posted on the Districts website. PROFESSIONAL CERTIFICATION Aires Consulting, a division of Gallagher Bassett Services, Inc. conducted this study in the interest of Chicago Ridge School District 127.5 to assist in meeting environmental obligations and regulations. In this respect, we hope the results of this study are useful.
