Figure2-1
Figure2-2
2. The remedial action process is represented in __________________.
Figure2-2
Figure2-3
3.Scoping activities typically begin with the collection of existing site data, including data from previous investigations such as the preliminary assessment and site investigation.
True
False
4.Scoping the RI/FS process is represented in ____________________.
Figure2-4
Figure2-3
5.A baseline risk assessment is developed to identify the existing or potential risks that may be posed to human health and the environment by the site. This assessment also serves to support the evaluation of the no action alternative by documenting the threats posed by the site based on expected exposure scenarios. Because this assessment identifies the primary health and environmental threats at the site, it also provides valuable input to the development and evaluation of alternatives during the FS.
True
False
6.The development of alternatives requires (a) identifying remedial action objectives,(b) identifying potential treatment, resource recovery, and containment technologies that will satisfy these objectives,(c) screening the technologies based on their effectiveness, implement ability & cost and(d) assembling technologies and their associated containment or disposal requirements into alternatives for the contaminated media at the site or for the operable unit.
True
False
7.The dispersal pathways for contaminants are represented in _________________.
Figure2-8
Figure2-9
8.Time-critical removal actions are actions initiated in response to a release or threat of a release that poses a risk to public health or the environment, such that cleanup or stabilization actions must be initiated within 6 months following approval of the Action Memorandum.
True
False
9.The identification of exposure pathways is illustrated in _______________.
Figure2-11
Figure2-12
10.The typical flowchart for time critical/non time critical removals is represented in _____________________.
Figure2-15
Figure2-16
11.Typical time-critical removal actions include Fences to limit access to the site, Drainage control to limit the off-site migration of contaminants, Capping or containment of the contaminants on the site, Removal of containers of waste remaining on the site & provision of alternative water supplies to citizens impacted by contaminated water.
True
