April 6, 2017 Mr. Chad Wiese Madison Metropolitan School District Building Services 4711 Pflaum Road Madison, WI 53718 Subject: Water Testing for Lead Marquette Elementary/OʹKeeffe Middle School 1501 Jenifer St./510 Thornton Ave. Dear Mr. Wiese: As requested by the Madison Metropolitan School District (MMSD), TRC Environmental Corporation (TRC) performed testing for lead in water at Marquette Elementary/OʹKeeffe Middle School. Testing Procedures Water testing was performed consistent with the United States Environmental Protection Agency s (USEPA s) guidance document 3Ts for Reducing Lead in Drinking Water in Schools: Revised Technical Guidance (USEPA 2006). The 3Ts document suggests an action limit of 20 parts per billion (ppb) for lead, but MMSD has selected a more conservative action limit of 15 ppb. TRC collected samples from cold water outlets on the interior of the buildings, including: hallway drinking fountains, classroom drinking fountains, water bottle refill stations, kitchen food preparation sinks, Family and Consumer Education (FACE) classroom sinks, faculty lounge sinks, nurse s office sinks, \\NTAPB MADISON\MSN VOL6\ \WPMSN\PJT2\274235\0000\MADISON SD WATER TESTING REPORT.DOCX

Preliminary sample locations were identified by maps provided by MMSD. Following completion of sampling, TRC prepared a map of each school annotated with the final sample locations and identification numbers for each outlet. See Appendix A: Location Map. Water sampling was conducted on March 15 & 25, 2017. During sample collection, each 250 ml bottle was marked with a school identification number (220) followed by the unique sample point identifier (e.g., 220 1 A, 220 1 B). Consistent with USEPA guidance, two samples were collected from each of the cold water outlets being tested. The first sample collected was the first draw sample (also called an A sample ). The first draw sample is the first flow of water from the outlet into the bottle and represents the water standing in the fixture. The second flush sample (also called a B sample ) was collected into a new sample bottle after the water had been allowed to continuously flow from the outlet for 30 seconds. The flush sample represents the water from the plumbing line behind the wall and outlet. Flush samples from refrigerated taps were sampled after 15 minutes of continuous flow (rather than 30 seconds) to account for water that resides in the cold water reservoir. At the tap nearest the incoming source water supply, only a single flush sample was collected. With assistance from MMSD and school staff, TRC attempted to collect samples after the tap was left unused for a period of 8 hours, but no longer than 18 hours, as recommended by the USEPA guidance. This required sampling in the early morning hours and over weekends. Upon completion of a sampling event, the sample bottles were packaged and shipped under proper chain of custody to TestAmerica in Savannah, GA a Wisconsin NR 149 certified drinking water laboratory (certification #999819810). Analytical Method Analysis for lead was performed using the EPA Method 200.8 (inductively coupled plasma with mass spectrometry) and achieved detection limits of 1.0 ppb or less. Samples Collected and Analytical Results TRC assessed a total of 66 fixtures within this school. Fixtures that were broken or not in use were documented as such and not sampled. Of the 61 first draw samples collected from the school, 12 had results greater than or equal to the MMSD action level of 15 ppb for lead. At locations where the A sample lead results were 15 ppb or greater, the lab analyzed the corresponding B sample. Of the 12 \\NTAPB MADISON\MSN VOL6\ \WPMSN\PJT2\274235\0000\MADISON SD WATER TESTING REPORT.DOCX
Madison Metropolitan School District Lead in Water Testing April 6, 2017 Marquette Elementary/OʹKeeffe Middle School Page 3 B samples analyzed, 1 met or exceeded the 15 ppb action level. A table listing the analytical results by outlet sampled is included in Appendix B. Recommendations Although not required under the USEPA guidance, TRC agrees with MMSD s conservative decision to suspend the use of water at fixtures where the A sample result is 15 ppb or greater until that fixture has been repaired or replaced and re tested. Once analysis of all lead water testing data from an individual building is complete, TRC can help devise a longterm operation and maintenance plan based on USEPA guidance. TRC appreciates the opportunity to assist MMSD with this project. If you have any questions or comments concerning this report, please call James at (608) 826 3666.

Samples were not able to be collected at sample point 6 (no sample port), 21, or 45 (no water or not enough water). 4. J indicates that result is less than the reporting limit but greater than or equal to the method detection limit, and the concentration is an approximate value. 5. The sample number is derived with the MMSD school identification number (e.g., 010) followed by a unique sample point identifier (e.g., 1, 2, 3, etc.). Fixtures with multiple taps include an additional locator (e.g., TAP 1, TAP 2). The first draw sample is then identified with the A suffix and the flush sample identified with a B suffix.
