Importance: High | contacted the DTMB help desk re my Inability to access the VA Tech study web site. The prablern is an our and. Trying to remotely remedy the situation did not work, so a ticket has been submitted anc | was asked to also submit the attached form, which requires the signature of a deputy director or higher. Since Sue Moran is not in the office, Mi need this kicked up the chain a3 appropriate for a signature. Thanks

The prabiem is not with their website, it's with our internet connection. i can bring the web site up on my iPhone and I’ve been able to briefly open ihe website from my camputer, but cannot navigate the site, | may have to go elsewhere (Big B or home) to get ¢ good connection.

Thanks, Corinne-

Fyl only The Virginia Tech website nas been down and Linda is working with the principal investigator of the Virginia Tech sturdy to obtain further information,

Additionally as Linda Dykema noted last week, the city water supply is in compliance with the lead rule, and the DEQ has not seen a change in the city's compliance with the lead rule since switching to the Flint River source.

I apologize for the delay in responding more specifically to this assignment, it took some time to review our Childhood Lead Poisoning Prevention program data to see if it might contribute to the understanding of the situation in Flint with their water supply. Here is what we found: We looked at lead testing results for May 2014-April 2015, which is the 12 month time frame just after Flint started drawing their water from the river (water source changed in April 2014). We compared lead testing rates and lead testing results to the same time frame for the previous 3 years, to see if there were any patterns that suggested that there were increased rates of lead poisoning after the water supply was switched. Per the attached charts — e Lead testing rates remained about the same from year to year (chart on the right). e There was a spike in elevated blood lead tests from July-September 2014 (chart on the left, gold line). *® However that pattern was not terribly different from what we saw in the previous three years, especially in 2011-2012 (we are working with our Epidemiologist to statistically verify any significant differences). ¢ Wecommonly see a ‘seasonal effect’ with lead, related to people opening and closing windows more often in the summer, which disturbs old deteriorating paint on the windows, sills and sashes. Window fans frequently blow and spread the lead dust from the deteriorating paint to other parts of the room/house. We suspect that the summer data spike may be related to this effect. ® Ifthe home water supply lines and/or river water were contributing to elevated blood lead tests, we 51 xxxEND_PAGE:treasury01_b29_4586_4669_69 expected that the increased rates would extend beyond the summer, but they drop quite a bit from September to October, stayed low over the winter, and are just starting to tail up again in the spring of 2015. So upon review, we don’t believe our data demonstrates an increase in lead poisoning rates that might be attributable to the change in water source for Flint. We recognize that lead exposure via the water is only a small piece of what may be happening for families in Flint, however, we hope the information is helpful. Nancy Peeler
