Based upon the most recent information reviewed for the Dover Municipal Landfill Site and the data in the original public health assessment, The NH DPHS and ATSDR conclude that the Dover Municipal Landfill Site is not an apparent public health hazard. This conclusion is based on the current lack of exposure to site-related contaminants through ingestion of groundwater. This exposure pathway appears to represent the major way that residents around the site could be exposed to site-related contaminants and, therefore, should be the main basis for this determination. The potential exposure pathways for this site, on-site soil, on- and off-site air, and off-site surface water do not appear to be significant routes that residents could be exposed, based on the limited data available.

There is a small chance that past exposure to vinyl chloride from one private drinking water well could be a health hazard. This exposure reportedly ended in 1981 and lasted a maximum of 11 years.

Since the direction of groundwater flow at the Dover Municipal Landfill is towards the Bellamy Reservoir and the Cocheco River, there is a potential for future risk of exposure to contaminants migrating off-site from the landfill, as the Bellamy Reservoir is used as a drinking water supply for nearby municipalities, and the Cocheco River is used by the public for recreational purposes. However, with the implementation of the proposed cleanup plan for the site and continued monitoring of area groundwater and surface waters, the potential future risk of human exposure to contaminants from the landfill is not expected to pose a threat to public health.

It was not possible to evaluate the possible health consequences of exposure to volatile organic compounds at a school bus stop, because of a lack of adequate air monitoring.


The NH DPHS and ATSDR continue to concur with the Recommendations of the April 12, 1989, Health Assessment for the Dover Municipal Landfill Site.

Public Health Action

No additional public health actions are recommended at this time.

Public Comment

The Addendum to the Dover Municipal Landfill Public Health Assessment was available for public review and comment from September 28, 1992 through October 27, 1992. The Public Comment Period was announced in local newspapers. Copies of the public health assessment were made available for review at the Dover Public Library in Dover, New Hampshire and the U.S. EPA Region I Records Center in Boston, Massachusetts. In addition, the addendum to the public health assessment was sent to 3 individuals or organizations who had requested that they receive copies. No comments were received.
