Longley, K., G. Hanna, AND B. Gump. REMOVAL OF DBCP FROM GROUNDWATER - VOLUME 2 - FIELD PILOT PLANT OPERATION. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-91/047 (NTIS PB91234609), 1991.
Description:
Static bottle-point and dynamic Freundlich adsorption isotherm determinations were performed on groundwaters containing different pesticide contaminants: , 2- dibromo-3-chloropropane (DBCP), ethylenedibromide (EDB), and 1, 2-dichloropropane (DCP). ield tests were carried out under ambient environmental conditions with natural variabilities in water quality which can affect pilot plant performance. hese water quality variabilities included a large variance in temperature during the lengthy period of field operations. oth static and dynamic isotherm data, the latter determined from two systems of different scale, were shown to be indicative of carbon use data for GAC at exhaustion. his finding is significant since static isotherm data are easier and less costly to develop. arbon use determinations were made for both DBCP and EDB. o decrease in DBCP or change in carbon use could be attributed to bacteria enumerated by the heterotrophic plate counts. owever, bacterial metabolic products could be a source of material adsorbing onto the GAC.
