- Currently, there is no exposure to site-related contaminants in base drinking water above levels of concern. Base drinking water meets all state and federal requirements. Active remediation is ongoing to prevent contaminant migration and future contamination of the Haven well, and water is monitored regularly to ensure compliance with drinking water standards. Therefore, future exposure is unlikely. Past exposure to TCE and nitrates were unlikely to have resulted in adverse health effects. Based upon an evaluation of contamination and exposure levels to groundwater used as a base drinking water supply, this exposure pathway is categorized as no apparent public health hazard.
- Past fishing, swimming, and wading in Peverly and Bass ponds posed no public health hazard from detected contamination. Currently the ponds are in a wildlife refuge, and recreational use is restricted. Should land use change, it would be wise to periodically evaluate exposure to fish contaminant levels detected under the long-term monitoring plan.
- Currently the IRP sites do not pose public health hazards. All contaminated areas have been assessed, and necessary interim and long-term remedial actions have been completed, are ongoing, or are planned. Future exposures to contaminants at IRP sites are unlikely to occur because of institutional controls that restrict access to, and use of, contaminated soils and groundwater.
- While there are no data on indoor air quality at Pease AFB, limited data on soil gas do not suggest that current indoor air quality problems would be expected. Based upon a review of existing data on contamination levels and potential exposures, this pathway is currently determined to pose no apparent public health hazard.
- No exposures of concern are occurring presently, and ongoing remedial activities, environmental monitoring, and developmental oversight are in place to prevent future exposures.
