Attached is the draft report for the Doyle Ryder Elementary school in Flint. Please review the report for content. Note that this report includes new language regarding outlets not sampled for being out of service so please review carefully. Jack you may forward this on to OEA staff that are assigned to finalize and convert into a publication. Once complete please send the final copy back to George and | to take a last look before we release the report. Thanks everyone. Stephen Busch, P.E.

Steve, {have read the report for Brownall Stem Academy and it loaks good te me. joe

Importance: High Steve, thave read the draft assessment review for Brownell and cio not have any issues with the cortent. Andy 8. Neuman Assistant Chief Plumbing Division Burewu of Construction Codes Department of Licensing and Regulatory Affairs [email protected]

Attached is the draft report for the school sampling conducted at Brownell STEM Academy school for comment. Joe and Andy please let me know if there are any issues with content. | believe | have incorporated formatting consistent with the last report for Eisenhower. Note faucet CFO07 was above the take action level for both lead and copper. As this was the only location with copper above this level and actions related to lead would also address copper, | added a paragraph on copper for this faucet in the lead section. Once reviewed Tracy Jo will work with OEA to get it finalized and provide back to me for final review before George distributes the report. Stephen Busch, P.E.

The assessment identified the following potential sources of lead leaching i i Lead solder joints on copper piping Brass valves and brass fittings Brass components in fixtures Galvanized piping samples (P41 and P2 flushed for 30 secon was flushed for anothe fter tumirig in the tap. The water was then ple (F01) was collected. Finally, the water 125-mililiter sample (F02) was collected. ad sources located deep in the supply plumbing of included one site near the building service line, one site near te at the far end of the plumbing system. At each of these r samples. The 10 samples were collected immediately after ively, without any flushing time in between. three sites, staff collec turning on the tap, and WATER SERVICE INFORMATION A four-inch diameter cast iron water service line enters the main school building in the mechanical room located in the middle of the building. Piping in the boiler room immediately transitions into galvanized metal piping and then into copper piping with lead solder joints for cold water lines. Two separate copper cold water supply lines exit the mechanical room. One through the north wall in the west corner appears to serve fixtures in the north end of the main wing of the school building. A second line exits the south wall and appears to serve fixtures in the south end of the main wing, and then continue over and serve fixtures in the west wing of the school building. Copper piping with lead solder joints continue to branch off of the copper supply lines. Hot water is distributed in continuous loops that feed from and return to a central xxxEND_PAGE:deq19_b04_0306_0721_406 water heater in the mechanical room. Hot water piping material, where exposed, was copper piping with lead solder joints. Brass valves were seen throughout the building. Qutlets With Lead Levels Greater Than 15 Parts per Billion The DEQ recommends school facilities take action if samples from any drinking water outlets show lead levels greater than 15 parts per billion. Based on the sampling conducted at 23 faucets/fountains on October 31, 2015, the following 12 drinking water outlets had lead water level results greater than 15 parts per billion. Each of these 12 outlets is listed below with its sample results, including a description of the potential source(s) of lead, and recommended actions for the school to take. Outlet: Bubbler Drinking Fountain, (DW001) Location: North Hallway, across from Classroom 12 Results: P1=64 parts per billion, P2=4 parts per billio F01=2 parts per billion, FO2=non-detect These results suggest the highest contributio bubbler itself. This bubbler fixture is made of cl brass connection on the underside of the unit. the unit also contains some brass components, in a brass valve. : These re hig ion of lead may be

Tracy, {have attached the photo you requested, Joe

Does anyone have ¢ picture that can go in this report for the following location? Outlet: Sink Faucet (02CF034) Location: Classroom 208, southwest wall Results: P1=19 parts per billion, P2=12 parts per billion, F1=3 parts per billion, F2=2 parts per billion These results suggest the highest contribution of lead may be from the faucet and its connecting plumbing. The base of this faucet is chrome plated brass, and has a brass connection on the underside of the sink. Connecting plumbing in the Image cabinet under the sink should be checked for brass components and copper piping Available with lead solder. No Replacement of this faucet and its connection plumbing with lead-free materials will significantly reduce lead exposure at this location. If replacement is not currently feasible, sample results indicate that flushing this tap for 3 minutes following periods of stagnation is likely to reduce lead concentrations and lead exposure. xxxEND_PAGE:deq18_b216_1650_1651_1 Thanks, Tras, Ao

Andy, As we discussed over the phone, we are trying to figure out who would have relevant records and who would be in the best position to work with a school to complete a facility plumbing profile as described in the attached. This could also include a mapping layout of the building plumbing system that could then be used to help develop best practice operational procedures for the building staff. Stephen Busch, P.E.
