Method to stimulate and sustain the anaerobic biodegradation of light non-aqueous phase liquid

摘要

A method for treating LNAPL source zones using a cost effective LNAPL source zone technology to degrade residual LNAPL, by introducing bioremediation amendments comprising nutritional supplements in quantities, locations, and depths required to stimulate and sustain the anaerobic biodegradation of an LNAPL source zone; monitoring the LNAPL source zone for adverse conditions that decrease anaerobic LNAPL biodegradation; eliminating any identified adverse conditions to sustain LNAPL biodegradation; and maintaining the water with nutritional supplements in quantities, locations, and depths required to stimulate and sustain the anaerobic biodegradation of LNAPL.

1. A method for treating LNAPL source zones using a cost effective LNAPL source zone technology to degrade residual LNAPL, the method comprising the steps of:
a) introducing bioremediation amendments to an LNAPL source zone; b) monitoring the LNAPL source zone for one or more of the following: dissolved phosphate, nitrogen, sulfate, trace metals, hydrogen sulfide, and LNAPL biodegradation activity; c) eliminating any identified adverse conditions to sustain LNAPL biodegradation; and d) maintaining the bioremediation amendments to stimulate and sustain the anaerobic biodegradation of LNAPL.
