PUBLIC HEALTH ASSESSMENT
MCADOO, SCHUYLKILL COUNTY, PENNSYLVANIA
Based on information reviewed, PADOH concludes that this site represents no public health hazard. There is no evidence of current or past exposures related to the site and future exposures are unlikely. Also, there are no community-specific health outcome data that exists to indicate the site has had an adverse impact on health. No completed pathways of exposure exist that are site-related. A potential but unlikely pathway of exposure exists at each location. The MKT location off-site sediment in the Little Schuylkill River is a potential pathway of exposure. This is an unlikely pathway, however, because of the quality of the water secondary to the acid mine drainage. At the MBS location, the subsurface soil is contaminated with low-level PAHs to which workers could potentially be exposed through incidental ingestion if any construction activities would occur. Even then, the cancer risk is only a low (perhaps no) increased risk. No acute or intermediate health effects would be expected at either location.
The health concerns raised by the community include odors emanating from the MKT location, the concern of an increased cancer risk in the McAdoo area related to the site, and a concern of health effects from their drinking water (see Community Health Concerns subsection). Air monitoring indicate that no emissions from the area are expected to cause adverse health effects. Health outcome data were analyzed and results are negative. Prior remedial actions implemented at the McAdoo Associates site have mitigated the major risks to human health (2). The MKT location is now capped (8).
A past, present, and future completed exposure pathway exists for people near the MKT location
who are ingesting non-site related lead present in their water. The presence of lead in residential
wells represents a public health problem, especially to young children.
Cease/Reduce Exposure Recommendations
Through remediation, reduce the potential for the continuing contamination of nearby subsurface soil, water/sediments, and groundwater at the MKT location.
Site Characterization Recommendations
Routine monitoring of groundwater should be conducted at both the MKT location and the MBS location to assure that no contamination of the potable water supplies occurs and to monitor the levels and the extent of contamination.
Health Activities Recommendation Panel (HARP) Recommendation
The data and information developed in the McAdoo Associates 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 for the site; however, non-site related lead exposure through drinking water has occurred and is occurring in some of the population near the site. Community involvement to provide information to the affected families about lead exposure is 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 for the McAdoo Associates site contains a description of action to be taken by ATSDR at and in the vicinity of the site subsequent to the completion of this public health assessment. The purpose of the Public Health Action Plan is to ensure that this public 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. The public health action to be implemented by PADOH and ATSDR is as follows:
PADOH will provide information concerning lead to the affected population.
