GLOSSARY

Acute:
Occurring over a short period of time. An acute exposure is one which lasts for less than 2 weeks.


Agency for Toxic Substances and Disease Registry (ATSDR):
The principal federal public health agency involved with hazardous waste issues, responsible for preventing or reducing the harmful effects of exposure to hazardous substances on human health and quality of life. ATSDR is part of the U.S. Department of Health and Human Services.


Aquifer:
An underground formation composed of materials such as sand, soil, or gravel that can store and/or supply groundwater to wells and springs.


Chronic :
A long period of time. A chronic exposure is one which lasts for a year or longer.


Contaminant :
Any chemical that exists in the environment or living organisms that is not normally found there.


Dose :
A dose is the amount of a substance that gets into the body through ingestion, skin absorption, or inhalation. It is calculated per kilogram of body weight per day.


Epidemiology :
The study of the occurrence and causes of health effects in human populations. An epidemiological study often compares two groups of people who are alike except for one factor, such as exposure to a chemical or the presence of a health effect. The investigators try to determine if any factor (i.e., age, sex, occupation, economic status) is associated with the health effect.


Exposure :
Contact with a chemical by swallowing, by breathing, or by direct contact (such as through the skin or eyes). Exposure might be short-term (acute) or long-term (chronic).


Groundwater :
Water found underground that fills pores between materials such as sand, soil, or gravel. In aquifers, groundwater often occurs in quantities where it can be used for drinking water, irrigation, and other purposes.


Hazardous substance :
Any material that poses a threat to public health and/or the environment. Typical hazardous substances are materials that are toxic, corrosive, ignitable, explosive, or chemically reactive.


Indeterminate public health hazard :
Sites for which no conclusions about public health hazard can be made because data are lacking.


Media:
Soil, water, air, plants, animals, or any other part of the environment that can contain contaminants.


Model Toxics Control Act (MTCA) :
The hazardous waste clean-up law for Washington State.


Monitoring wells :
Special wells drilled at locations on or off a hazardous waste site so water can be sampled at selected depths and studied to determine the movement of groundwater and the amount, distribution, and type of contaminant.


No apparent public health hazard :
Sites where human exposure to contaminated media is occurring or has occurred in the past, but the exposure is below a level of health hazard.


No public health hazard :
Sites for which data indicate no current or past exposure or no potential for exposure and therefore no health hazard.


Organic :
Compounds composed of carbon, including materials such as solvents, oils, and pesticides, which are not easily dissolved in water.


Parts per billion (ppb)/Parts per million (ppm) :
Units commonly used to express low concentrations of contaminants. For example, 1 ounce of trichloroethylene (TCE) in 1 million ounces of water is 1 ppm. 1 ounce of TCE in 1 billion ounces of water is 1 ppb. If one drop of TCE is mixed in a competition-size swimming pool, the water will contain about 1 ppb of TCE.


Plume :
An area of contaminants in a specific media such as groundwater.


Route of exposure :
The way in which a person might contact a chemical substance that includes ingestion, skin contact, and breathing.


Volatile organic compound (VOC) :
An organic (carbon-containing) compound that evaporates (volatilizes) easily at room temperature. A significant number of the VOCs are commonly used as solvents.
