Volume 1 -- Errata Sheet
Page 18:The first sentence of the second paragraph is incorrect and should be deleted.
Page 59:The sediment samples discussed in the Sediment section and listed in Table 15 were
likely obtained from nearby springs and therefore should be considered off-site samples rather
than on-site samples.
Page 71:The second sentence in the Off-Site Ambient Air section refers to Conard's Branch,
which is not associated with Lemon Lane. The reference to Conard"s Branch should be deleted.
Page 73:References to clay cap in the Interim Removal and Remedial Measures and Current
Status sections are incorrect. A soil cover was used at Neal's Dump.
Page 76:The comparison value in Table 22 should read 0.01 parts per million (ppm).
Page 105:The sentence at the top of the page reads, "Ambient air is a present and future
completed exposure pathway for nearby residents as long as there is PCBs present in the site
associated springs." ATSDR believes that the levels of PCBs now present in the stream (water
and sediments) or likely to be present in the future will result in only minimal ambient air levels
(nondetectable or barely detectable concentrations under routine sampling protocols). Thus,
ATSDR does not consider ambient air to be a present and future completed exposure pathway
under any feasible exposure scenario. The sentence should be deleted.
Page 105:Change 38 ppm to 68 ppm at the bottom of page.
Page 107:The completed exposure pathway for ambient air in Table 39 was likely only in the past.
Page 108:The value shown in the second sentence under the Off-Site Surface Water/Sediment
section should read 7.7 ppm .
Page 125:Under the Off-site Sewage Sludge section, the sludge came from the Winston-Thomas
Facility, not from Westinghouse.
Page 129:Under the Off-site Surface Water section, the 0.19 ppm is a sediment level, not a water
concentration. The phrase "in sediments" should be added to the end of the fourth sentence.
Page 142:Delete the reference to antibiotics in the first paragraph of page 143. Not all antibiotics
may pose an increased risk. It has been suggested that the antibiotic novobiocin might possibly
pose an increased risk in individuals exposed to PCBs. See "Toxicological Profile for
Polychlorinated Biphenyls, Draft for Public Comment (Update), February 20, 1996."
Page 147:The 3 micrograms per cubic meter (µg/m3) level cited in the last paragraph is not a
lowest-observed-adverse-effect-level (LOAEL).
Page 169:Change "MW" (monitoring well) to "W" (private well) in Anderson Road Landfill
Recommendation 1.
Pages 164 - 171:The Conclusions and Recommendations sections are superseded by Volume III.
