1. What is systemic sampling?

A. A sample collection strategy in which an individual determines the locations from which he or she will collect samples by using a program or table that lists the locations at random
B. A sample collection strategy in which an individual determines the locations from which he or she will collect samples by using a system that identifies specific locations throughout the area where the individual can collect samples from on a regular basis
C. A sample collection strategy in which an individual determines the locations from which he or she will collect samples based on information about the areas that have been contaminated in the past and the areas that now appear to be contaminated
D. A sample collection strategy in which an individual collects samples from convenient locations without any apparent system

2. A hospital is attempting to determine the appropriate way to dispose of a piece of medical equipment that has been classified as a Class A low-level radioactive waste, but only has a half life of approximately three days. The hospital is required to

A. isolate the equipment until the radioactive atoms completely decay and then trash it.
B. bury the equipment so that it is no less than five meters from the surface until the radioactive atoms completely decay.
C. turn the equipment over to a low-level radioactive waste disposal facility.
D. isolate the equipment in a pool of water in a secure, contained space until the radioactive atoms completely decay.

3. What is source reduction?

A. Any procedure or action that allows a facility to reduce the amount of solid or hazardous waste that it would typically produce
B. Any procedure or action that allows a facility to convert hazardous waste into something that a consumer can use
C. Any procedure or action that allows a facility to manage less waste than it would typically be required to manage
D. Any procedure or action outside the recycling or treatment process that allows a facility to release less pollution or hazardous waste into the environment or the waste stream than it would typically release

4. An emergency plan describing the procedures that a facility will follow to eliminate or reduce the impact that a hazardous substance may have on individuals outside the facility and/or the impact that the substance may have on the environment if an accidental release occurs is known as

A. an RCRA contingency plan.
B. a SARA community response plan.
C. a HAZWOPER plan.
D. a HazCom plan.

5. A Primary NAAQS is

A. a standard established by the Environmental Protection Agency (EPA) that is designed to limit the amount of a specific pollutant that can be released into the air to reduce the impact that that particular pollutant has on the environment and the welfare of individuals living in that environment.
B. a standard established by the Environmental Protection Agency (EPA) that is designed to limit the amount of a specific pollutant that can be released into the air to reduce the impact that that particular pollutant has on the health of individuals living in the polluted area.
C. a standard established by the Clean Air Act that requires a facility to keep the amount of hazardous air pollutants (HAPS) that the facility produces as low as reasonably possible.
D. a standard established by the Clear Air Act that requires an organization to assess the effect that a new facility will have on the air quality of the area in which the new facility will be built before it is built.

Answers & Explanation

1. B: Systemic sampling is a sample collection strategy in which an individual determines the locations from which he or she will collect samples by using a system that identifies specific locations throughout the area where the individual can collect samples on a regular basis. A sample collection strategy in which an individual determines the locations from which he or she will collect samples by using a program or a table that lists the locations at random (Choice A) is known as random sampling or simple random sampling. A sample collection strategy in which an individual determines the locations from which he or she will collect samples based on information about the areas that have been contaminated in the past and the areas that now appear to be contaminated (Choice C) is known as judgmental sampling. A sample collection strategy in which an individual collects samples from convenient locations without any apparent system (Choice D) is known as haphazard sampling.

2. A: A facility that is attempting to dispose of a Class A low-level radioactive substance with a half-life that is less than 65 days is only required to isolate the substance until the radioactive atoms completely decay. The facility can then discard the waste as normal trash as long as the facility has the appropriate permit from the Nuclear Regulatory Commission to store the radioactive material for the required length of time. The other three answer choices refer to disposal methods that the hospital could use, but that are not actually required for a Class A low-level radioactive substance with a short half-life. Choice B refers to a method that is required to dispose of a Class C low-level substance. Choice C refers to a method that the hospital could use, but is not required to use for a Class A low-level substance. Finally, Choice C refers to a disposal method that is only required for a high-level radioactive substance.

3. D: Source reduction, which is also known as pollution prevention, refers to any procedure or action outside the recycling or treatment process that allows a facility to release less pollution or hazardous waste into the environment or the waste stream than it would typically release. Waste minimization refers to any procedure or action that allows a facility to reduce the amount of solid or hazardous waste that it would typically produce (Choice A). Recycling refers to any procedure or action that allows a facility to convert hazardous waste into something that a consumer can use (Choice B). Waste reduction refers to any procedure or action that allows a facility to manage less waste than it would typically be required to manage (Choice C). It is important to note that a procedure does not necessarily have to belong to a single category and that a procedure may fall into more than one of these categories in some cases.

4. A: An emergency plan describing the procedures that a facility will follow to eliminate or reduce the impact that a hazardous substance will have on individuals outside the facility and the impact that the substance may have on the environment if an accidental release occurs is known as an RCRA contingency plan. A SARA community response plan describes the procedures that emergency personnel outside the facility (such as firefighters, police, Hazmat teams, etc.) will follow to respond to a chemical release if an accidental release occurs at that particular facility. A HAZWOPER (Hazardous Waste Operations and Emergency Response) plan identifies specific individuals within the facility that will respond to an accidental release and describes the procedures that these individuals will follow. A HazCom (Hazard Communication) plan describes the procedures that an employee should follow to prevent the employee and other individuals from being exposed to the hazardous substance in the event of an emergency.

5. B: A Primary National Ambient Air Quality Standard (NAAQS) is a standard established by the Environmental Protection Agency (EPA) that is designed to limit the amount of a specific pollutant that can be released into the air to reduce the impact that that particular pollutant has on the health of individuals living within that particular area. A Secondary NAAQS is a standard established by the EPA that is designed to limit the amount of a specific pollutant that can be released into the air to reduce the impact that that particular pollutant has on the environment and the welfare of individuals living within that environment. A National Emission Standard for Hazardous Air Pollutants (NESHAP) is a standard established by the Clean Air Act that requires a facility to keep the amount of hazardous air pollutants (HAPS) that the facility produces as low as reasonably possible. The Prevention of Significant Deterioration (PSD) rule is a standard established by the Clean Air Act that requires an organization to assess the effect that a new facility will have on the air quality of the area in which the new facility will be built before it is built.
