APPENDIX C

Comments received on the public comment release

The comments listed here were received by ATSDR in response to the public comment period forthe MCAS Cherry Point Public Health Assessment (April 22, 1996). No comments on accuracyof stated facts are included. If a statement was questioned, we verified or corrected it.

Comment: The text needs to mention that the aquifers must be monitored to determine ifcontaminants are migrating vertically from the contaminated aquifers above. Informationregarding the air station's sampling program (sampling frequency, analyses performed andreporting process, etc.) should be presented, and the quality of groundwater samples collected atthe wellheads of the supply wells should be monitored to ensure adequate protection of humanhealth and the environment.

Response: Because there are no exposures to groundwater at this site and future exposures arenot expected, we do not deem this information necessary for the document. Further, various IRPdocuments describe the air station's plans and progress in remedial actions and monitoringplans. Long-term monitoring plans for the aquifers will be described in remedial decisiondocuments. Those IRP documents are available at the Havelock Public Library and the MCASLibrary.

Comment: Several wells in the industrial area are used for non-potable water supply; they areindustrial cooling water supply wells. Should these wells become contaminated, would there be arisk associated with their use in any way?

Response: No. No one is expected to be exposed to the water used for industrial cooling. Thewater is recirculated in a closed system.1

Comment: If Goose Creek is upstream of the air station, how would these brown bullheads beaffected by any contamination originating from the air station?

Response: The brown bullheads in Goose Creek are not affected by air station contaminationand are not expected to be. Goose Creek is a control creek in a non-industrial area (10kilometers upstream and across the Neuse River) used for comparison to creeks surrounding theair station. Since contamination in brown bullheads from the creeks surrounding the station andthe control creek are similar, the station apparently has not adversely impacted brown bullheadsin Slocum and Hancock Creeks.
