Permanent Retrievable Storage
Permanent retrievable storage
Permanent retrievable storage is a method for handling highly toxic hazardous wastes on a long-term basis. At one time, it was widely believed that the best way of dealing with such wastes was to seal them in containers and either bury them underground or dump them into the oceans. However, these containers tended to leak, releasing these highly dangerous materials into the environment .
The current method is to store such wastes in a quasipermanent manner in salt domes, rock caverns, or secure buildings. This is done in the expectation that scientists will eventually find effective and efficient methods for converting these wastes into less hazardous states, in which they can then be disposed of by conventional means. One chemical for which permanent retrievable storage has been used so far is the group of compounds known as polychlorinated biphenyl (PCB)s.
Permanent retrievable storage has its disadvantages. Hazardous wastes so stored must be continuously guarded and monitored in order to detect breaks in containers or leakage into the surrounding environment. In comparison with other disposal methods now available for highly toxic materials, however, permanent retrievable storage is still the preferred alternative means of disposal.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
