Linda Here is the response fram CDC regarding adult BLLs: The COC value for blood lead in pregnancy is below 5, with medical removal protection for pregnant waren with levels p= 10 with their dactor’s recornmendation. (citation: For other adults the javel depends on whether the individual is exposed at work which uses the OSHA standards. Mark Mark D.

1 xxxEND_PAGE:deq21_b009_0009_0011_1 Linda Thanks for the additional information. As a follow-up to my earlier message, the National Science Foundation is apparently arranging funding to several investigators to evaluate the engineering aspects of the Flint water system to find a solution. Although Flint has initiated plans to construct a water line that will tap into Lake Huron as their water source, they may still have issues with their aging water distribution system. NIEHS wanted to know if ATSDR, MDHHS, or Flint Health Dept is planning to evaluate the public health implications of the problems in the water system. As you know, NCEH has both a Safe Water Program and a Lead Program that could possibly be involved, but only at the request of the state. If the elevated lead exposure is limited to just this one residence that has since been remediated, then federal involvement would not seem to be appropriate. Let me know if there is something more to evaluate. Mark

FYI - our Director's office asked for information, so | called DEQ for the scoop.
