National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Solid Oxygen Source for Bioremediation in Subsurface Soils (Revised).

PB95155149

Publication Date	1994
Personal Author	Vesper, S. J.; Murdoch, L. C.; Hayes, S.; Davis-Hoover, W. J.
Page Count	18
Abstract	Sodium percarbonate was encapsulated in poly(vinylidene chloride) to determine its potential as a slow-release oxygen source for biodegradation of contaminants in subsurface soils. In laboratory studies under aqueous conditions, the encapsulated sodium percarbonate was estimated to release oxygen over about a two-month period. Microbial survival in the persence of encapsulated sodium percarbonate was markedly increased compared to the unencapsulated compounds. In laboraotry studies, the encapsulated sodium percarbonate was used to provide oxygen as an electron acceptor for microorganisms during the biodegradation of propylene glycol.
