Public Health Assessment
NAVAL WEAPONS STATION YORKTOWN, CHEATHAM ANNEX
WILLIAMSBURG, YORK COUNTY, VA
CERCLIS NO. VA3170024605
ATSDR received several editorial comments on the public comment release of the Public Health Assessment for the Naval Weapons Station Yorktown, Cheatham Annex. Those comments were addressed in this version.
ATSDR also received some specific comments that are addressed below. We did not receive any comments from individual citizens or citizen groups.
The evaluation to "Potential Exposure to Contaminants Associated with the Penniman Shell Loading Plant" implies that additional investigations or remediation of that area is not necessary because there is limited contact with the area. High concentrations of metals and PAHs have been detected in some of these areas. In particular, lead concentrations in excess of 7,000 ppm was measured at the TNT graining house sump. ATSDR concluded that the levels would not be a concern because the area is heavily vegetated and exposure would be infrequent. However, if the area is developed in the future, these contaminants would be a concern as exposure becomes more frequent. VDEQ supports the cleanup of this area as part of the ongoing installation restoration program.
ATSDR modified the background portion of that section to include VDEQ's support of additional environmental investigations and remediation. ATSDR originally concluded that additional studies and/or remedial action could be necessary if redevelopment of that area was planned. ATSDR concurs with VDEQ that the concern is for future exposure to the contaminants of that area, whether on not the exposure results from redevelopment activities. Therefore ATSDR modified the discussion portion of that section and the conclusions to clarify that additional environmental investigations or remedial actions may be necessary if land use changes occur which allow greater public contact with the area containing the TNT graining house sump and catch box ruins.
