Groupings of organic waste chemicals based on sorption, biotransformation and hydrolysis at standard conditions for application to the deep subsurface environment
Chemical and biological reactions of organic hazardous wastes disposed to injection wells at depths down to 7000 feet deep are assessed. At these depths, the major reactions involving organic wastes include hydrolysis, biotransformation and sorption. However, experimental data on reactions of organics in the deep subsurface are sparse or nonexistent. Tables are given on values for hydrolysis, sorption and biotransformation reactions obtained from research publications, mostly at 25/degree/C and atmospheric pressure. It is suggested that the more plentiful data on reactions at the land surface be used to approximate the rates of hydrolysis and biotransformation and sorption equilibrium by taking into account the expected subsurface environment. For example, predictive methods will take into consideration a deep subsurface environment which has: a higher temperature and pressure than the land surface; fewer kinds of microorganisms and a substantially lower concentration of microorganisms; lower organic carbon levels; and, highly saline ground waters. 58 refs., 1 figs., 12 tabs.
