Based on what we learned from this past Saturday, see attached revised working draft. There may be items | am unaware of and am interested in making sure this procedure is accurate. We figured out some time saving steps for paper work and labeling units that | adjusted in the draft document for next time. | am still a little uncertain about noting the name of the sample unit, and the test code. (i.e. my ‘normal work’ might be 36VO sample unit for CXVO test code, etc.). Perhaps for George to answer, if the sample unit is 32CC (125 ml) or 36CC (1 liter) is it assumed that the test is for lead and copper so no need to write the test code?

Copper was also analyzed. 32CC is used for the small battles. 36CC for the 4 liter batthes. Both codes are for lead and copper analyses.

Date: Friday, October 30, 2015 1:03:00 PM Copper was also analyzed. 32CC is used for the small bottles. 36CC for the 1 liter bottles. Both codes are for lead and copper analyses.

| made some adjustments to the working draft sampling protocol base on my experience from the Oct 24" sampling event. Looking for consistency on what we call stuff: container/sample unit/sampling containers/bottle; sample sites/sample locations/outlet; Sample collection location code/unique outlet code etc. We have two Collect the Samples sections that could be brought together, me thinks: Step 6, and the How to Collect an Initial First Draw, How to Collect Flush Samples could be merged. | didn’t save a copy of the pre-filled Request for Analysis form from last Saturday’s event. We were using the 36CC sample unit for lead and copper. Was copper also analyzed? Or just lead? | only saw draft lead data. What is the DEQ Drinking Water Lab test code for this testing protocol?

| am planning on joining the sampling team for this Saturday's event. Just let me know where to meet, time, who | am teamed up with, and which school to report to, with street address, and the time they are expecting us. Are we meeting again this Friday to make sure we are all on the same page? Lois Elliott Graham, R.S., M.S.A.

Importance: High Hi everybody, Well it’s Thursday and | have nothing from GCHD so it looks like DEQ will be doing the sampling this weekend. We are going to do two schools this weekend (Brownell STEM Academy and Eisenhower Elementary). | think we should continue to have a DEQ staff person accompany DLARA staff during the evaluation and it would be very helpful to have DLARA staff present for the sampling. | believe that we should have two teams of three for the sampling consisting of two DEQ staff and one DLARA staff. The DLARA staff person can act as the timer and answer questions. We should have one team per school and sample the schools simultaneously. If Tony Sitko can arrange it, | would like to go back and do the 3 sets of 10 sequential samples at Freeman elementary. | will not be part of the sampling teams at Brownell or Eisenhower but | can go back and get the sequential samples and go back and forth to see how things are going. Saturday is Halloween so if anyone has plans and cannot attend please let me know so that we can find replacements. | want to stress that this is voluntary duty and | do not want to guilt anyone into this. If we cannot get two full teams together we may have to limit the sampling to just one school so we need to get a head count ASAP. Steve, Please work with Joe and Tony to ensure that we can access the schools. xxxEND_PAGE:deq15_b583_2078_2080_2 Everyone please chime in if you have any questions, comments or concerns. Thank you!

Importance: High | have attached the data for the sampling that was done at Freeman Elementary. These are Preliminary Results that have NOT gone through the entire data validation process. | do not expect any changes but | want to provide that clarification at the very beginning. Shelly and Linda please take a look as | would like to discuss the data at tomorrow’s conference call. Each sampling point has four samples (P1, P2, F01, F02) P1= 1S Preliminary Draw of 125 mls of water P2= 24 Preliminary Draw of 125 mls of water FO1= 3"4 Sample in the series. This sample was taken after a 30 second flush after P2 Fo2= 4th sample in the series. This sample was taken after a 2 minute flush after FO1. In general one would expect P1 samples to have the highest values and F02 samples to have the lowest values and overall this held very true. We can discuss further tomorrow. George George L.

Importance: High | think we need to meet today to evaluate Saturday's sampling event. Overall | think it went really well but | also think there are some lessons learned that we should discuss and perhaps include in the protocol. Tracey Jo, Can you please get us a conference room and schedule a time? | am free for most of the day today but earlier is better than later. Thank you! George George L.
