Good morning, Tom
Just an update on the Flint sampling so folks know what's going on. As we had initially discussed, the only way
to really see what the lead levels are throughout and where the lead is actually coming from at Ms. Walters!
place is to do sequential sampling prior to the removal of the LSL. I spoke to Ms. Walters and she said that the
water was shut off inside her home, so it can actually be turned back on, so Jennifer and I picked up sample
bottles from the R5 office and we will be dropping them off at Ms. Walters place today on the way home from
the MDEQ RTCR meeting. Pat Cook has confirmed that following the disconnection from Detroit, Flint has not
been operating any corrosion control treatment, which is very concerning given the likelihood of LSLs in the
city. We do not know how many LSLs there are in Flint and according to Ms. Walters, neither does the city.
She said that they do not know where any LSLs are, based on their records, so other than what appears to be a
very long one at Ms. Walters' place, we don't have confirmation of any others at this point. Since they were used
extensively here in RS, it is likely there are more. No idea how many, though.
Marc Edwards (from Virginia Tech) was kind enough to offer to analyze this round of samples so she will
shipping the samples to Marc for analysis. I asked that he measure phosphate as well, so that we have some data
on that. As we discussed, R5 will send an additional set of bottles to Ms. Walters for the follow-up monitoring
once the LSL is removed. I spoke to Mike Prysby on Friday and he said that the city was going to remove the
LSL fully this Wednesday. I also brought a camera with me and will take some pictures while we are at Ms.
Walters place as well.
Apparently, according to Ms. Walters, the water director appears to be telling residents that the high lead from
Ms. Walters residence is from the internal plumbing and that a reporter she was talking to, as well as others, has
confirmed that this is what residents are being told. Ms. Walters indicated that the line coming into the home
appears to be galvanized pipe. If this is true, it is possible that her portion of the service line, from the home to
the property line, is not lead and that the city-owned portion of the service line is the only source of lead here.
The sample results should help to clarify where the lead is coming from.
