Overview
The Edwards Air Force Base located in Antelope Valley in Southern California was built to test new aircraft and help integrate them into the U.S. Air Force. The site became a flight test center after World War II. As an air base, many chemicals and fuel are stored here and throughout its history there have been spills and improper disposals. This became an environmental hazard when the contaminants began to seep into the ground. The EPA, the Air Force, and two state agencies signed a Federal Facility Agreement in 1990 to address this issue.
Activities That Led to Pollution
The activities that led to the pollution were the storage of fuel, Volatile Organic Compounds, metals, and other chemicals. Years of flight testing and rocket

VOCs can easily become vapors or gasses making it very toxic to any in the area who inhale it. Perchlorate, which came from the many years of rocket fuel resting, 1, 4-dioxane, and various metals are non-volatile contaminants found in some areas. N-Nitrosodimethylamine (NDMA) is a semi volatile organic compound suspected of being a carcinogen and is a known hepatotoxin. Some of the less harmful contaminants include landfills that may contain unexploded artillery, weapons or other munitions related materials. Perfluorinated Compounds (PFCs), an unregulated group of chemicals, has also been found and is being investigated at different sites on the base.
Harmful Effects
Trichloroethene has been associated with hepatotoxicity. Exposure also produces decreased appetite, gastrointestinal irritation, headaches, skin irritation. Chronic exposure produces ataxia (loss of full control of bodily movements.), decreased appetite, headache, short-term memory loss, sleep disturbances, and vertigo.
Tetrachloroethene is a group 2A carcinogen. This means that it is likely a probable carcinogen. It is also a Central Nervous System depressant and due to its fat solubility it can enter through the skin and cause irritation. Acute exposure to tetrachloroethylene can cause incoordination drowsiness, dizziness, and headaches. Large doses, however, can cause unconsciousness and death. Chronic exposure can cause changes in reaction time, memory, attention and vision, and
The 82 private wells and two springs had detectable amounts of benzene contaminated by soil that was affected by years of mismanagement and improper disposal of chemical waste. 42 of the private wells and both springs had
Prior to the late 1950s the site was used as an excavation pit for sand and gravel. The quarry was subsequently used for the disposal of waste materials from 1950 until 1966. 10 acres of the 28-acre site has been used as a disposal area for several hazardous waste contaminants that included volatile organic compounds (VOCs) such as benzene, tetrahydrofuran, toluene, vinyl chloride and xylene; other organics such as phenols and PCBs as well as lead. The main area of contamination is in the southern half of the 10 acre area which encompasses about 6 acres which
The southern portion is being cleaned up by the Air Force under Superfund. The reason the northern portion of the base is being clean up under the Safe Drinking Water Act is because it is currently still being used for training by the Army. The Air Force no longer uses the southern portion for training purposes. There are 10 major plumes of concern. Each site has been contaminated by chemical/fuel spills, fire training activities, landfills, and drainage structures.
John-Manville Corp is the site of 150-acre asbestos disposal. Around 3 million cubic yards of specification products and wastewater sludge were disposed of at the site. They stopped operations in the site in 1998 and former manufacturing buildings were torn down in 2000-2001. Asbestos is the main problem, during clean up asbestos contamination was found outside of the fence line. Outboard Marine Corporation is on the north section of the Waukegan Harbor. It was an outboard-boat-motor manufacturing plant. The contaminants include PCB’s, OMC that are used in hydraulic fluids, and TCE. Yeoman Creek Landfill is on the northwest side of Waukegan. The landfill was open from 1959-1969. The landfill did not have a bottom liner and the soil was permeable. The liquid from the landfill contained chemicals with elevated concentrations of metals and ammonia. Gas from the landfill was detected off site. North Shore Gas North Plant has was contaminated with residuals the past plan operations. North Shore Gas South Plant includes 1.9 acre former MGP facility along Pershing Road and bordering areas where MGP residuals are now found. MGP’s are industrial facilities that produced gas from coal, oil, and other
In 1969 it was discovered that the site was leaching due to a lack of a bottom liner. The landfill was leaching volatile organic compounds (VOC), polychlorinated biphenyls (PCB) and explosive landfill gases (LFG).
Also depicted in this paper is the type of cancers caused by each chemical and other related health problems associated with each chemical. Finally, the role of government agencies such as FDA, EPA and OSHA in preventing excessive amount or zero amounts of toxic chemicals from entering the environment will be discussed. The last paragraphs will enumerate the inferred conclusion from my research on Agent Orange, DDT and Benzene.
Fort Riley consists of over 100 thousand acres and contains multiple sources that are contaminated. There are landfills, hospitals, motor pools, and burn pits along with other facilities. There are well within the Camp Funston Landfill that have been contaminated with vinyl chloride along with other VOCS. Ground water around the dry cleaning facilities on the post have had PCE detected in them. Due to a fire training pit near the Marshall Army Airfield, ground water around this location has been contaminated with VOCS. With Fort Riley being a military installation, the landfill has been reported to have contaminants including degreasing solvents and waste oils. Mercury was also found to have been deposited into the landfill. The landfill is near the flood plain of the Kansas River and is considered to be the most concerning problem within Fort Riley. The river is commonly used for recreational activities such as fishing. The bald eagle, which is listed as an endangered species, is
Most on-base contamination was because of past disposal of hazardous waste due to their activities like maintenance of aircraft, tanks, and trucks, landfill operations etc that contributed to the contamination of soil and groundwater. The contaminants include volatile organic compounds (VOCs) like benzene, 1,2- dichloroethane, carbon tetrachloride, Chloromethane, trichloroethylene (TCE), total 1,2-dichloroethene (1,2-DCE), trans-1,2-DCE, and vinyl chloride, spent oils, fuels, PCB, pesticides (44-DDD and 44-DDT), metals and herbicides.
What has been brought to light in recent years is the effects of these chemicals on the body’s immune response. By introducing these toxic chemicals into the body, the potency of the immune system is compromised. More commonly than not, the body’s magnificent defense system will kick in and destroy foreign invaders but all it can take is an overwhelming amount of chemicals to slow or even shut down the body’s response systems. A large amount of these types of chemicals introduced into the body at one time would be considered acute toxicity and could even cause death. Additionally, a small amount of these poisonous substances brought into the body over a long period would be considered chronic toxicity and can have detrimental effects on the body’s natural response (Hoernschemeyer 55-57). This information is startling enough to want to make a change from conventionally grown food to pesticide-free organic
Toluene - Toluene is a solvent that has been shown to cause severe allergic reaction, inflammation, and immune system malfunction. It has also been shown to interfere with the proper functioning of your nervous system.

The next Superfund that has greatly influenced the environment of Butler County is the Skinner Landfill. The Landfill is on 85 acres in West Chester (2). The facility was privately owned and was never actually licensed, so it closed in the 1970's (5). The landfill contains about 100 drums of chlorinated organics, and heavy metals. Along with the presence of the drums is the fact that a nearby lagoon was once used as a disposal for these contaminants, and that the site had problems with unauthorized dumping (5). Fortunately, no contaminants have been discovered leaving the site (5). The presence of these
These substances not only trigger liver, heart, kidney and nervous system deterioration, but also cause lung impairment and cancer.
Assessments began to take place in the mid 1980’s, shortly after the site made the National Priorities list in 1983. Relevant standards and guidance levels were used to measure the effect of the Helen Kramer Landfill. The initiation of the EPA’s remedial investigation and feasibility study deemed the nature of the Helen Kramer landfill as an extreme risk to the environment, characterizing the site “by randomly placed, uncompacted, and uncovered refuse, with numerous settlement cracks which vented methane and water vapor” (2). According to the EPA, several million gallons of chemical wastes and over two million cubic yards of solid waste were estimated to have been disposed of at the landfill (2). Studies were performed by the EPA, New Jersey Department of Environmental Protection, federal natural resource trustees in the U.S. Fish & Wildlife Service, and the National Oceanic and Atmospheric Administration to evaluate the onsite and nearby environmental effects due to the landfill. During these studies, contaminants were detected in air, sediments, and aquifers, including high levels of volatile organic compounds and heavy metals in the air and sediments. VOCS and heavy metals expose humans to carcinogens, developmental toxicants, and reproductive toxicants. The assessments also detected numerous contaminants such as (but not limited to),
Even if you haven’t heard of it, a chemical named Chlorpyrifos, or better known as Dow Chemical Company’s Nerve Gas Pesticide, may be inside you. This pesticide, which belongs to a class of chemicals developed as a nerve gas made by Nazi Germany, is now found in food, air, and drinking water. Studies show that it damages the brain and reduces I.Q.s while causing tremors among children. It has also been linked to lung cancer
