The Agency for Toxic Substances and Disease Registry (ATSDR), a federal public health agency of the Department of Health and Human Services, has released its public health assessment for the Hanscom Air Force Base site.

According to the report, the Hanscom site's groundwater is not a public health hazard because groundwater onsite and immediately offsite is not a source of drinking water.

Past exposure to surface soil is an indeterminate public health hazard because ATSDR scientists lacked sampling data about conditions before site remediation activities.

However, ATSDR considers current and future contact with surface soil to pose no public health hazard because:

• Some soil at the sanitary landfill has been capped with clean fill to prevent exposure to potential contaminants. Where soil is uncapped, contaminants are not present in quantities sufficient to cause adverse health effects.
• Contamination at the former filter bed is inaccessible. The area has been capped, fenced and posted to prevent access.
• Soil at the Scott Circle landfill has been capped and contains no contaminants at levels expected to cause adverse health effects.

Contaminants in surface water and sediment in the Shawsheen River and in wetlands and other bodies of water surrounding the Hanscom site are not present in sufficient concentrations to cause adverse health effects in the past, currently or in the future.
