TABLE OF CONTENTS
- Occurring over a short time [compare with chronic].
- 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.
- An underground formation composed of materials such as sand, soil, or gravel that can store and/or supply groundwater to wells and springs.
- Occurring over a long time (more than 1 year) [compare with acute].
- A substance that is either present in an environment where it does not belong or is present at levels that might cause harmful (adverse) health effects.
- Dermal Contact:
- Referring to the skin. For example, dermal absorption means passing through the skin.
- Contact with a substance by swallowing, breathing, or touching the skin or eyes. Exposure may be short-term [acute exposure], of intermediate duration, or long-term [chronic exposure].
- Water beneath the earth's surface in the spaces between soil particles and between rock surfaces [compare with surface water].
- 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.
- The act of swallowing something through eating, drinking, or mouthing objects. A hazardous substance can enter the body this way [see route of exposure].
- The act of breathing. A hazardous substance can enter the body this way [see route of exposure].
- Soil, water, air, plants, animals, or any other part of the environment that can contain contaminants.
- Model Toxics Control Act (MTCA):
- The hazardous waste cleanup 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.
- Compounds composed of carbon, including materials such as solvents, oils, and pesticides which are not easily dissolved in water.
- A volume of a substance that moves from its source to places farther away from the source. Plumes can be described by the volume of air or water they occupy and the direction they move. For example, a plume can be a column of smoke from a chimney or a substance moving with groundwater.
- Remedial investigation:
- The CERCLA process of determining the type and extent of hazardous material contamination at a site.
- Route of exposure:
- The way people come into contact with a hazardous substance. Three routes of exposure are breathing [inhalation], eating or drinking [ingestion], or contact with the skin [dermal contact].
- Surface Water:
- Water on the surface of the earth, such as in lakes, rivers, streams, ponds, and springs [compare with groundwater].
- US Environmental Protection Agency (EPA):
- Established in 1970 to bring together parts of various government agencies involved with the control of pollution.
- 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.
