Completed exposure pathway:
A pathway of exposure is considered completed when all five elements are present. A completed pathway connects the source of the material to people.
- Source
- Media
- Exposure point
- Exposure route
- People
Source: EPA
Will exposure from a completed pathway affect my health?
Whether or not a person experiences health effects from exposure to materials in the environment depends on a combination of several site-specific factors including.
- Kind of material released
- Amount of material available at the exposure point
- Physical and chemical form of the material
- Environmental conditions
- Length of exposure time
George AFB’s Weapons Storage and Assembly Area and Southeast Disposal Area
The Southeast Disposal Area’s RW-09 radioactive disposal site is physically located about a ¼ mile upstream of the Drinking Water Supply Wells for George AFB, Adelanto, CA, several homes, and the former Victor Valley Country Club. Unfortunately, the groundwater flows northeast from the SEDA, directly toward these drinking water supply wells. This created a potential exposure to tens of thousands of civilians, and military [Read More…]
1991-xx-xx – George AFB’s Missing Completed Exposure Pathways Assessment
The Air Force refused to release the pre-1991 epidemiological, environmental, and health investigations conducted at George AFB that were requested under FOIA. These studies may be the result of Congressman Brown’s 1990 request to Major General Burton R. Moore to investigate the radioactive contamination at George AFB.
George AFB’s Persistent Organic Pollutants (POP)
Victorville Army Airfield / George Air Force Base (AFB) used organochlorine pesticides, before they were banned, to protect its buildings against termites and other pests. The following pesticides and their breakdown products were detected under and around the George AFB Family Housing: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, and lindane. The levels of aldrin, dieldrin, and chlordane and their breakdown products were so [Read More…]
Drinking Water – Completed Exposure Pathways
George Air Force Base’s contaminated drinking water provided a Completed Exposure Pathway (CEP) Supply wells → water → civilians, military personnel and their family members, and surrounding community This contaminated drinking water provided the following “Completed Exposure Pathways” Ingestion: Drinking water, cooking Dermal Contact: bathing, showering, swimming pool, occupational exposures Inhalation of volatile organic compounds (VOCs): showering, swamp coolers The Department of Defense (DOD) and Air Force [Read More…]
Industrial Waste – Completed Exposure Pathways
From 1965 to 1 December 1981 (16 years), the Air Force dumped 5,578,400 gallons of industrial waste containing known carcinogens into the sanitary sewer, which emptied into the sewage treatment plant (STP), and the STP discharged directly into the STP’s percolation ponds. However, the Air Force determined that the unlined percolation ponds, the soil, and the groundwater were NOT contaminated based on one [Read More…]
