RESPONSIVENESS SUMMARY

A draft of this public health assessment for the Duell and Gardner Landfill site wasreleased for public comment on February 16, 1994. The public comment period lasted untilMarch 18, 1994. No comments were received by the MDPH in this period. Additional commentsand new information on the site will be considered by MDPH and ATSDR for futureassessments of, or consultations on, the site.

FOOTNOTES

1. Pica behavior is an abnormal consumption of non-food materials,such as soil, most often seen in children under 5 years of age.

2. The numbering used in this Public Health Assessment follows thatused in Reference 1, except that the round 3 locations forPW-2, -14, and -15 have been renumbered PW-21, -22, and -23, respectively. The welllabeled PW-21 in Reference 7 is here labeled PW-24.
