PUBLIC HEALTH ASSESSMENT

AVCO LYCOMING-WILLIAMSPORT DIVISION
WILLIAMSPORT, LYCOMING COUNTY, PENNSYLVANIA


CONCLUSIONS

Based on the information reviewed, PADOH has concluded that this site represents no apparent public health hazard, since available data do not indicate that humans are being or have been exposed to levels of contaminants that would be expected to cause adverse health effects. The investigation of off-site groundwater has determined that there were no private wells in the contaminant plume and presently all residents use the public supply with the reserve supply wells remediated. Findings, to date, indicate that future exposure could only occur if a well was dug into the contamination plume.

Health outcome data could not be addressed to the specificity desired; however, since there is indication that past, present, and future exposures did not and will not occur to an extent that would produce adverse health effects, health outcome data evaluation should not be necessary. A review of cancer mortality for Williamsport City did not indicate that cancer mortality in Williamsport City differed significantly from Pennsylvania.


RECOMMENDATIONS

Cease/Reduce Exposure Recommendations

Develop institutional controls as part of the remediation plan to avoid future exposure to contaminated groundwater.

Site Characterization Recommendations

Additional sampling of the groundwater plume should be performed to better determine the extent of contamination (e.g., across Lycoming Creek) and to assure that further migration is not occurring.

Health Activities Recommendations Panel (HARP) Recommendations

The data and information developed in the AVCO Lycoming-Williamsport Division Public Health Assessment have been evaluated for appropriate follow-up health actions. The ATSDR Health Activities Recommendation Panel (HARP) determined that no follow-up public health actions are indicated. ATSDR will reevaluate this site and conduct appropriate public health actions, if new data become available that indicate a need to do so.


PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the AVCO Lycoming site contains a description of actions to be taken by ATSDR and/or PADOH at and in the vicinity of this site subsequent to the completion of this health assessment. The purpose of the PHAP is to ensure that this health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment. Included in this plan is a commitment on the part of ATSDR/PADOH to follow up on this plan to ensure that it is implemented.

No public health actions are indicated at this time.
