How a chemical enters a person's blood after the chemical has been swallowed, has come into contact with the skin, or has been breathed in.

Acute Exposure:
Contact with a chemical that happens once or only for a limited period of time. ATSDR defines acute exposures as those that might last up to 14 days.

Adverse Health Effect:
A change in body function or the structures of cells that can lead to disease or health problems.

The Agency for Toxic Substances and Disease Registry. ATSDR is a federal health agency in Atlanta, Georgia that deals with hazardous substance and waste site issues. ATSDR gives people information about harmful chemicals in their environment and tells people how to protect themselves from coming into contact with chemicals.

Background Level:
An average or expected amount of a chemical in a specific environment. Or, amounts of chemicals that occur naturally in a specific environment.

A group of diseases which occur when cells in the body become abnormal and grow, or multiply, out of control

See Comprehensive Environmental Response, Compensation, and Liability Act.

Chronic Exposure:
A contact with a substance or chemical that happens over a long period of time. ATSDR considers exposures of more than one year to be chronic.

Completed Exposure Pathway:
See Exposure Pathway.

Comparison Value (CV):
Concentrations or the amount of substances in air, water, food, and soil that are unlikely, upon exposure, to cause adverse health effects. Comparison values are used by health assessors to select which substances and environmental media (air, water, food and soil) need additional evaluation while health concerns or effects are investigated.

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA):
CERCLA was put into place in 1980. It is also known as Superfund. This act concerns releases of hazardous substances into the environment, and the cleanup of these substances and hazardous waste sites. ATSDR was created by this act and is responsible for looking into the health issues related to hazardous waste sites.

A belief or worry that chemicals in the environment might cause harm to people.

How much or the amount of a substance present in a certain amount of soil, water, air, or food.

See Environmental Contaminant.

Dermal Contact:
A chemical getting onto your skin. (see Route of Exposure).

The amount of a substance to which a person may be exposed, usually on a daily basis. Dose is often explained as "amount of substance(s) per body weight per day".

Dose / Response:
The relationship between the amount of exposure (dose) and the change in body function or health that result.

The amount of time (days, months, years) that a person is exposed to a chemical.

Environmental Contaminant:
A substance (chemical) that gets into a system (person, animal, or the environment) in amounts higher than that found in Background Level, or what would be expected.

Environmental Media:
Usually refers to the air, water, and soil in which chemical of interest are found. Sometimes refers to the plants and animals that are eaten by humans. Environmental Media is the second part of an Exposure Pathway.

U.S. Environmental Protection Agency (EPA):
The federal agency that develops and enforces environmental laws to protect the environment and the public's health.

Coming into contact with a chemical substance.(For the three ways people can come in contact with substances, see Route of Exposure.)

Exposure Assessment:
The process of finding the ways people come in contact with chemicals, how often and how long they come in contact with chemicals, and the amounts of chemicals with which they come in contact.

Exposure Pathway:
A description of the way that a chemical moves from its source (where it began) to where and how people can come into contact with (or get exposed to) the chemical.

ATSDR defines an exposure pathway as having 5 parts:
  1. Source of Contamination,

  2. Environmental Media and Transport Mechanism,

  3. Point of Exposure,

  4. Route of Exposure; and,

  5. Receptor Population.

When all 5 parts of an exposure pathway are present, it is called a Completed Exposure Pathway. Each of these 5 terms is defined in this Glossary.

How often a person is exposed to a chemical over time; for example, every day, once a week, twice a month.

Hazardous Waste:
Substances that have been released or thrown away into the environment and, under certain conditions, could be harmful to people who come into contact with them.

Health Effect:
ATSDR deals only with Adverse Health Effects (see definition in this Glossary).

Indeterminate Public Health Hazard:
The category is used in Public Health Assessment documents for sites where important information is lacking (missing or has not yet been gathered) about site-related chemical exposures.

Swallowing something, as in eating or drinking. It is a way a chemical can enter your body (See Route of Exposure).

Breathing. It is a way a chemical can enter your body (See Route of Exposure).

The National Priorities List. (Which is part of Superfund.) A list kept by the U.S. Environmental Protection Agency (EPA) of the most serious, uncontrolled or abandoned hazardous waste sites in the country. An NPL site needs to be cleaned up or is being looked at to see if people can be exposed to chemicals from the site.

No Apparent Public Health Hazard:
The category is used in ATSDR's Public Health Assessment documents for sites where exposure to site-related chemicals may have occurred in the past or is still occurring but the exposures are not at levels expected to cause adverse health effects.

No Public Health Hazard:
The category is used in ATSDR's Public Health Assessment documents for sites where there is evidence of an absence of exposure to site-related chemicals.

Public Health Assessment. A report or document that looks at chemicals at a hazardous waste site and tells if people could be harmed from coming into contact with those chemicals. The PHA also tells if possible further public health actions are needed.

A line or column of air or water containing chemicals moving from the source to areas further away. A plume can be a column or clouds of smoke from a chimney or contaminated underground water sources or contaminated surface water (such as lakes, ponds and streams).

Point of Exposure:
The place where someone can come into contact with a contaminated environmental medium (air, water, food or soil). For examples:
the area of a playground that has contaminated dirt, a contaminated spring used for drinking water, the location where fruits or vegetables are grown in contaminated soil, or the backyard area where someone might breathe contaminated air.

A group of people living in a certain area; or the number of people in a certain area.

Public Health Assessment(s):
See PHA.

Public Health Hazard:
The category is used in PHAs for sites that have certain physical features or evidence of chronic, site-related chemical exposure that could result in adverse health effects.

Public Health Hazard Criteria:
PHA categories given to a site which tell whether people could be harmed by conditions present at the site. Each are defined in the Glossary. The categories are:
- Urgent Public Health Hazard
- Public Health Hazard
- Indeterminate Public Health Hazard
- No Apparent Public Health Hazard
- No Public Health Hazard

Receptor Population:
People who live or work in the path of one or more chemicals, and who could come into contact with them (See Exposure Pathway).

Route of Exposure:
The way a chemical can get into a person's body. There are three exposure routes:
- breathing (also called inhalation),
- eating or drinking (also called ingestion), and
- or getting something on the skin (also called dermal contact).

The Superfund Amendments and Reauthorization Act in 1986 amended CERCLA and expanded the health-related responsibilities of ATSDR. CERCLA and SARA direct ATSDR to look into the health effects from chemical exposures at hazardous waste sites.

Source (of Contamination):
The place where a chemical comes from, such as a landfill, pond, creek, incinerator, tank, or drum. Contaminant source is the first part of an Exposure Pathway.

Special Populations:
People who may be more sensitive to chemical exposures because of certain factors such as age, a disease they already have, occupation, sex, or certain behaviors (like cigarette smoking). Children, pregnant women, and older people are often considered special populations.

Superfund Site:
See NPL.

Harmful. Any substance or chemical can be toxic at a certain dose (amount). The dose is what determines the potential harm of a chemical and whether it would cause someone to get sick.

The study of the harmful effects of chemicals on humans or animals.

Urgent Public Health Hazard:
This category is used in ATSDR's Public Health Assessment documents for sites that have certain physical features or evidence of short-term (less than 1 year), site-related chemical exposure that could result in adverse health effects and require quick intervention to stop people from being exposed.


Comparison values represent media-specific contaminant concentrations that are used to select contaminants for further evaluation to determine the possibility of adverse public health effects. The conclusion that a contaminant exceeds the comparison value does not mean that it will cause adverse health effects.

Cancer Risk Evaluation Guides (CREGs)

CREGs are estimated contaminant concentrations that would be expected to cause no more than one excess cancer in a million (10-6) persons exposed over their lifetime. ATSDR's CREGs are calculated from EPA's cancer potency factors.

Environmental Media Evaluation Guides (EMEGs)

EMEGs are based on ATSDR minimal risk levels (MRLs). An EMEG is an estimate of daily human exposure to a chemical (in milligrams per kilogram per day) that is likely to be without noncarcinogenic health effects over a specified duration of exposure.

Maximum Contaminant Level (MCL)

MCL is the drinking water standard established by the U.S. Environmental Protection Agency (EPA). It is the maximum permissible level of a contaminant in water that is delivered to the free-flowing outlet. MCLs are considered protective of public health over a lifetime (70 years) for people consuming 2 liters of water per day.

Reference Media Evaluation Guides (RMEGs)

ATSDR derives RMEGs from EPA's oral reference doses. RMEG represents the concentration in water or soil at which daily human exposure is unlikely to result in adverse noncarcinogenic effects.



Site Summary

Prepared by:

Federal Facilities Assessment Branch
Division of Health Assessment and Consultation
Agency for Toxic Substances and Disease Registry















As part of the public health assessment process, the Agency for Toxic Substances and Disease Registry (ATSDR) conducted a site visit of the McGuire Air Force Base (McGuire AFB) Wrightstown, New Jersey, from November 29 through December 2, 1999. The purpose of the visit was to tour the site, meet with site representatives, and to gather the necessary information to prepare a public health assessment (Appendix A). ATSDR is mandated by Congress to assess the public health impacts of each site listed on the National Priorities List (NPL). Through the public health assessment process, ATSDR assesses site conditions from a public health perspective to determine whether potential exposure to site-related contaminants exist for the groundwater/drinking water, surface water, soil, biota, or air exposure pathways.

Based on our visit and a preliminary review of the data, ATSDR did find not any health threats at the McGuire AFB requiring immediate attention. ATSDR did note two potential exposure pathways or issues that require further study. ATSDR prepared this Health Consultation (Site Summary) to provide McGuire AFB with a brief summary of pathways and issues identified for evaluation. These pathways/issues include:

  • Potential off-base exposure to leachate of unknown composition near LF-03 (Landfill 2), north of McGuire AFB boundary.

  • Potential exposure to contaminants in surface water.

ATSDR presented these issues to the U.S. Air Force at an exit briefing on December 2, 1999 (See Appendix B for attendees). At the meeting, McGuire AFB agreed to collect leachate samples and consider precautions to prevent contact with the LF-03 leachate. Subsequent sampling data provided by McGuire AFB is summarized and included in this report.


Site Description

McGuire AFB is located on approximately 3,700 acre in the Borough of Wrightstown, Burlington County, New Jersey, approximately 18 miles southeast of Trenton, New Jersey, and 30 miles east of Philadelphia, Pennsylvania (see Figure 1). (Parts of the McGuire AFB also fall within New Hanover Township.) Primary on site features include: an air field situated in the central/southwest portion of the base consisting of active and inactive runs, taxiways, and parking aprons; industrial areas in the central-east portion of the base used for maintenance, storage, and supply functions; temporary and permanent housing along the perimeter of the base; and miscellaneous administrative areas throughout the base.

The base is bordered to the north by Wrightstown and to the east, south, and west by U.S. Army Fort Dix Military Reservation, which is used for U.S. Army training (see Figure 2). Other nearby communities include the townships of New Hanover, Pemberton, and Plumsted, and the community of Cookstown. Most of these areas are rural, but residential and commercial development is particularly notable in Borough of Wrightstown and a part of Pemberton Township known as Browns Mill. Four off-base areas also fall under the jurisdiction of McGuire AFB: The McGuire Middle Marker, the Boeing Michigan Aeronautical Research Center (BOMARC) Missile Facility; the Burlington petroleum, oil, and lubricants (POL) off-loading facility, and the McGuire AFB approach lights.

McGuire AFB is also located within the Pinelands National Reserve, an area subject to oversight by the New Jersey Pinelands Commission to protect its important natural and ecological resources. The base is drained by overland flow to a series of on-site streams, including, the North Run, the South Run, Bowkers Run, Jack's Run, and Larkin's Run. The North Run flows east along the northern boundary of the base and South Run flows east through the southeastern portion of the base. Both the North Run and South Run eventually drain into Crosswicks Creek east of McGuire AFB, which eventually drains into the Delaware River. Small areas of the base also drain into Jack's Run and Larkin's Run, which are also tributaries of the Delaware River.

Operational History

In 1937, a single dirt runway and several associated buildings were constructed on a portion of Fort Dix and adjacent farmland. The airfield, call Rudd Field, served as an adjunct to Fort Dix and was operated by the U.S. Army Air Corps. During the early years of World War II, extensive improvement were made to meet wartime training needs, including paving and expanding landing strips. In 1948, the airfield and associated facilities were transferred to the U.S. Air Force. The installation was designated McGuire AFB.

A variety of commands oversaw the base from 1945 through 1954. In 1954, it was assigned for use by Air Force airlift-oriented operations and several tenant organizations, including the New Jersey Air National Guard. At that time, the command operating the facility was known as the Military Air Transport Service. It was renamed the Miliary Airlift Command in 1966 and then renamed the Air Mobility Command in 1992. McGuire AFB has become the Air Mobility Command's East Coast mobility base, with the capability of providing quick, large-scale airlifts to place military forces into combat situations. In September 1994, the 305th Air Mobility Wing assumed operation of the base.

Site-related contamination, including petroleum products, solvents, and constituents of protective coatings, resulted from aircraft fueling and maintenance activities, fuel and weapons storage maintenance, and other activities supporting McGuire AFB's mission over the years. Aircraft fueling and maintenance have occurred primarily in a broad area in and near a series of industrial facilities bordering the east end of the runway area, as well as in the 3300-series buildings in the northwest corner of the base. Historically, bulk fuel storage has been located just to the east of the industrial area at a bermed tank farm with eight aboveground storage tanks containing aircraft fuel or heating oil.

Remedial and Regulatory History

In 1982, the installation restoration program (IRP) began investigating sites at McGuire AFB where hazardous materials might have been released to the environment. During the 1980s, preliminary investigations and site assessments were conducted at 17 sites identified at that time. These sites include:

  • Six landfills (LF-02, LF-03, LF-04, LF-19, LF-20, and LF-23), where general base refuse, coal ash, drums of waste oil, and/or other miscellaneous chemicals were discarded;

  • Three fire protection areas (FT-08, FT-11, and FT-13), where fire training practices often used waste oils and a variety of fuels;

  • Two storage areas, the Bulk Fuel Storage Area (ST-09) and the Defense Reutilization and Marketing Office (DMRO) Storage Facility (ST-07), where petroleum products, out-of-service transformers, or other hazardous materials were stored;

  • Two spill sites, the PCB spill site (SS-18) and the Aircraft Apron fuel leak (ST-22), where hazardous material or fuel were released;

  • A sludge disposal area, (WP-21), where the base's wastewater treatment plant sludge was disposed of; and

  • Miscellaneous areas, including the pesticide wash area (OT-06), where pesticide application equipment were rinsed; a civil engineering compound (OT-10), where waste solvents may have been stored; and a nondestructive inspection (NDI) shop drain field (OT-14), where waste containing emulsifiers, developers, and other chemicals were received.

Based on preliminary investigations, no further actions were proposed for 8 of the 17 sites: OT-06, OT-10, SS-18, LF-19, LF-20, WP-21, FT-08, and LF-23. Further investigations are underway at sites requiring additional study, including: remedial investigations at OT-06, and ST-22(1); feasibility studies at LF-02, LF-03, LF-04, ST-07, ST-09, FT-11, FT-13 and OT-14; and long term groundwater monitoring at sites LF-19, LF-20, and LF-23.

In addition to ongoing investigations, McGuire AFB conducted interim removal actions (IRAs) to reduce and control the spread of contamination. IRAs completed to date included removal of contaminated soil from ST-07, SS-18, and OT-06. Furthermore, McGuire AFB completed a remedial design for site ST-09 in 1992, initiated a bioventing pilot test for the site the same year, and implemented pilot-scale studies of free product recovery systems. In 1992, McGuire AFB inventoried all transformers on base, which indicated that 200 on-base transformers contained polychlorinated biphenyls (PCBs) above the regulatory limit of 50 parts per million. Subsequent to the inventory, McGuire AFB replaced all PCB-containing transformers by 1998.

McGuire AFB also investigated conditions at the off-base BOMARC Missile Facility, the Middle Marker site, and the Burlington POL off-loading facility because of concerns about potential historical releases. The investigations found no evidence of discharges or past releases for the Middle Marker site and the Burlington POL off-loading facility that required further actions. McGuire AFB will further evaluate the BOMARC Missile Facility site under the IRP. ATSDR will prepare a separate public health assessment for the BOMARC Missile Facility site.

On October 22, 1999, the U.S. Environmental Protection Agency (EPA) placed McGuire AFB on the NPL primarily for contamination associated with several of its landfills used for base refuse.


As a result of our November/December 1999 site visit, meetings, and a preliminary review of the data currently available, ATSDR identified the following issues as requiring further evaluation/action.

  • Potential off-base exposure to leachate near landfills.

During the site visit, ATSDR and base personnel found what appeared to be seeps (pools) of reddish-brown leachate forming below a storm water drain located downgradient of the LF-03 (Landfill 2) and the DMRO Storage Facility (ST-07). This leachate spring is along the northern boundary of the base and beyond the base's perimeter fence. McGuire AFB used the landfill from 1950-1956 for general base refuse and has used the DMRO Storage Facility since 1963 for storage of fuels. Sampling data summarizing the composition of the leachate were not available during our visit.

The seep is located adjacent to a branch of the North Run. The North Run is a shallow, narrow stream that flows east along the northern limits of the base property. On the other side of the North Run from the seep are both a former and an active trailer park. Another larger base housing area is located about a half mile away. Currently, there are no controls to prevent or limit access to the seep. Also, signs warning of possible hazards are not posted. ATSDR was concerned that the storm water drain may serve as a conduit for higher than expected concentrations of contaminants entering the North Run from either the landfill or the DMRO yard. People living nearby could come in contact with this material.

At the exit meeting on December 2, 1999, ATSDR shared its concern with base personnel. In response, McGuire AFB agreed to sample the leachate and also offered to assess measures aimed at preventing human contact with the leachate (e.g, installing a fence around the area where the leachate pools).

Since the site visit, ATSDR has received and reviewed results for leachate samples taken from pools near and downgradient of the landfill in 1991, 1992, and 1996. Low levels of volatile organic compounds, semivolatile organic compounds and pesticides were present in these leachate samples (See Appendix C). McGuire AFB personnel have recently confirmed these samples represent the same location noted during the site visit. Additional samples were collected by McGuire AFB personnel in March 2000. The low levels of organics found in this leachate do not indicate an immediate health hazard to an individual visiting the area briefly and infrequently.

  • Potential exposure to contaminants in surface water.

Several streams flow through McGuire AFB. The northern section of the base drains to North Run, and central portion drains to South Run. North and South Runs eventually drain into Crosswicks Creek. Certain areas in the southeast portion of the base drain to Bowker's Run, Jack's Run, and Larkin's Run, are tributaries of Rancocas Creek. Both Crosswicks Creek and Rancocas Creek eventually flow to the Delaware River. VOCs and metals from landfills (LF-03, LF-04, and possibly LF-20) and contaminants associated with oil/fuel components stored at ST-09 are believed to be entering the North Run and a tributary of the South Run, respectively. Because these streams eventually flow to off-base surface-water bodies, contaminants entering the streams may be carried to areas where people/recreational users could come in contact with them. In most cases, contaminant concentrations in the surface water are expected to decrease with dilution before reaching off-site areas accessible by the public. ATSDR will obtain sampling results from the Air Force and review the data along with information on use patterns of local surface water to determine whether a public health hazard exists.


The public health assessment process includes gathering information about health concerns voiced by members of the community. To begin this process, ATSDR interviewed base public affairs personnel who address community questions and concerns about McGuire AFB and reviewed the McGuire AFB Community Relations Plan (CRP). The base CRP includes a survey of environmental concerns voiced by members of the base community. ATSDR also met with other base personnel who may interact with community or may be aware of community concerns including: the support group commander, the judge advocate generals office, the public health officer, the ground safety officer, the manager of the base installation restoration program and the base bioenvironmental engineer.

Community health concerns about the base wastewater treatment plant, the aircraft noise, and the water quality have arisen sporadically. Because of recent publicized cleanup activities at the BOMARC Missile Facility site, much of the community concern focuses on health and safety hazards stemming from the BOMARC missile accident in the 1960s. As mentioned, ATSDR will evaluate the BOMARC Missile Facility site in a separate public health assessment where those concerns will be addressed.

ATSDR will continue to collect additional community health concerns relating to McGuire AFB through the public health assessment process. Community members can direct their health concerns to:

Program Evaluation and Records Information Services Branch
ATSDR, Division of Health Assessment and Consultation
Attention: McGuire Air Force Base/BOMARC
1600 Clifton Road, NE (E-56)
Atlanta, Georgia 30333

Community members can also telephone Tom Mignone, ATSDR's regional representative in New York City, New York, at 212-637-4306.


  • The leachate below Landfill 2 (LF-03) does not pose an acute health hazard.


Through the public health assessment process, ATSDR not only identifies potential public health hazards, but offers recommendations designed either to assist in our evaluation of hazards or to prevent adverse health effects resulting from potential exposure to harmful chemicals in the environment. ATSDR recommendations are as follows:

  • McGuire AFB should periodically assess the area below the LF-03 (Landfill 2) for changes in the existing leachate springs and to identify any new leachate springs. Additionally, the base should consider posting the landfill area to alert visitors to the potential for hazards.

  • ATSDR will address the potential exposure to contaminants discharged to the surface water in the McGuire AFB Public Health Assessment.
