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.

One outlet building in addition to the main school building was included in the assessment. The assessment identified the following potential sources of lead leaching into drinking water: Lead solder joints on copper piping Brass valves and brass fittings Brass components in fixtures Galvanized piping The assessment also identified 34 faucets or fountains that ide water for drinking, cooking, and/or food preparation, 32 faucets/fountains in the main school building, and two ‘aucets/fountains in the southernmost out buildin; uildings had no working out building, each in the order det ‘ollowing a stagnation period of over is staff collected four samples.

The _ Le : boiler room is located near the middle of the west side of the main building. The water line enters on the south side of the room. Piping in the boiler room for the cold water transitions into copper piping. In one area exposed from under pipe insulation, what appeared to be a lead bushing was observed. The cold water supply line exits the boiler room. It appears that beyond the boiler room, a cold water line heads towards the north corridor, and one heads towards the south corridor. The middle and southerly most out building is believed to be served from the main building. The skirting of the unit prohibited any assessment of the service line to this building. The northern most out building was not assessed due to its discontinued use. 2 xxxEND_PAGE:deq19_b05_0722_0778_44 Outlets 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.

Many faucets have an aerator/screen at the outlet. If the faucet is not replaced, the aerator/screen should be removed, inspected for particulate accumulations, scrubbed clean, and reinstalled. If particulates are found, the aerator/screen should be periodically checked and cleaned. Generally goa should be cleaned at least quarterly to remove scale, particulate accumulation, and | 12 xxxEND_PAGE:deq19_b05_0722_0778_54

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

visit. In follow-up to the Governor's Action Plan for the city of Flint, state and local resources are being marshalled to conduct lead and copper sampling at your school. Fiseliah Blehinialy (Need 10 cUsiomize for each e:ineil) is scheduled to be visited by Department of Licensing and Regulatory Affairs (LA RA) plumbing inspectors in order to perform an on-site assessment of the buildings plumbing prior to samples being collected for a lead and copper evaluation. In order to assist LARA staff to identify and prioritize sample sites, school staff should compile, collect, and review any records pertaining to the building plumbing. This includes building permits, plumbing permits, as built plans, and information about the service line and all potable water pipes, fixtures and appurtenances within the building. At a minimum, a diagram of each floor layout should be provided. In addition, answers to the following questions will help streamline the on-site assessment process. e When was the facility built? e Have new buildings or additions been added? If so, when were they added? If built since 1986, were lead-free plumbing and solder used? e When were the most recent plumbing repairs made and where were they located? e What are the potable water pipes in your facility made of and what is their location? Options include: lead, brass, copper, plastic, galvanized metal and other materials. What materials were used to solder the potable water pipes in your system? Are brass taps, fittings or valves used? Note the locations. e How many of the following outlets provide water for consumption: Bubblers, ice makers, water coolers and kitchen taps. Note their location. Include taps that might be used for making coffee or preparing formula. e What brands and models of water coolers (cooled drinking fountains) provide water in your facility and what is their location? e Do faucets have accessible screens and have they been cleaned? e Can you detect any signs of corrosion, such as leaks, rust-colored water or stains? e Is any electrical equipment grounded to water pipes? xxxEND_PAGE:deq15_b491_1864_1865_1 e Are there any records of previous water testing? LARA staff will be contacting you to set a date and time for the assessment. A school representative familiar with the building layout and plumbing system needs to accompany LARA staff as they conduct the assessment. A room reserved for records review should also available. xxxEND_PAGE:deq15_b491_1864_1865_2

Joe, In our discussions about school plumbing assessments we touched on the need code each tap so that when water sampling is done the sample codes match up with the tap coding provided in the plumbing assessment. The link below provides EPA’s example coding scheme for water outlets. This example may not be applicable in all cases given that some schools are likely to have multiple levels and others will have sinks in each room, but hopefully it gives you some indication of what is needed for tap coding as part of the plumbing assessment. Thanks again for your assistance. Example Coding Scheme for Water Outlets A drinking water bubbler (DW) on the 2nd floor (02) of the middle school (MID), the 15th outlet counted, might be coded as follows. e =6MID- 02- DW-015 e §=©6©DW= drinking water bubbler e WC = water cooler (chiller unit) xxxEND_PAGE:deq14_b0707_2206_2208_2 e CF = classroom faucet e «©KC = kitchen faucet, cold e = ©6©KH = kitchen faucet, hot e EC = home economics room, cold e EH = home economics room sink, hot e BF = bathroom faucet e «NS = nurse's office sink e §©6SC = service connector In addition to the unique outlet code, a unique sample identifier is necessary if more than one sample will be taken from an outlet. A flush sample would also require a unique identifier. The first draw (P) and flush (F) samples taken for the above outlet would be MID- 02- DW-015-P-01 and MID~ 02- DW-015-F-01 e =©P= primary (first draw) sample ° = flush e §©6©01 = first sample e 02 = second sample Stephen Busch, P.E.
