(320b) Chemical Decontamination of Spills in Water Streams

A review is presented of the information that is required to help clean up accidental and deliberate chemical spills in water streams. The review includes (a) current EPA, SBIR 9R-NC-07-1055 (closing date May 23, 2007)information that deals with decontamination, drinking water and wastewater security, and emergency response, (b) types of chemical spills--explosives, pathogens/biological agents/proteins, etc., mercury, PCBs, organic chemicals, hazardous chemicals, and metals,(c) methods for treatment of different chemical spills, and benefits of phytoremediation, (d) contaminants suitable for phytoremediation, (e) biological pathogens, (f) devices used for chemical contamination, (f) removal of EDCs (endocrine disrupting chemicals), (g) some clean up-methods (documents available online), (h) some examples of relevant government documents, (i) community's right to know, RCRA, Clean Water Act, etc,(j) relevant databases such as CAMEO, EFDB (Environmnetal Fate Data Base) (k) SQRTs (Screening Quick Reference Tables), (l) other useful databases (m) setting up a data base for a model compound for use by emergency responders and (n) diffusion-limited kinetics and involvement of free-radical mechanisms. The intent of the presentation is to provide a starting point to put together information in one place, so that one can build up a data base for one's personal use or need for chemical decontamination in water streams.
