|Status at this
|What does this mean?
|Human Exposure Under Control
Yes means assessments indicate there are no unacceptable human exposure pathways and EPA has determined the site is under control for current conditions site-wide.
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.
Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
- Response to the contamination has not begun; or
- The response has begun, but it has not yet generated information sufficiently reliable to evaluate whether there are any unacceptable human exposure pathways at the site.
|Groundwater Migration Under Control
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use
- All cleanup goals affecting current and reasonably anticipated future land uses of the site have been achieved, so there are no unacceptable risks; and
- All required land-use restrictions or other controls have been put in place; and
- The site has achieved Construction Complete status.
No means that one or more of these three criteria have not been met.
