    • Systems and methods for co-enhancing contaminant degradation such as LNAPL and DNAPL degradation. Embodiments of the inventive technology may relate to assuring adequate amounts (e.g., concentrations) of certain substances (e.g., nitrogen, electron acceptor, bacteria, microbial substrate) so that degradation of LNAPL and DNAPL is enhanced as intended. Any of the inventive methods may involve the amendment of groundwater with one or more particular substance (uric acid, electron acceptors, microbial substrate, as but a few examples) in order to enhance DNAPL, and perhaps also, LNAPL degradation.
    • 共同提高污染物降解的系统和方法,如LNAPL和DNAPL降解。 本发明技术的实施方案可以涉及确保某些物质(例如氮,电子受体,细菌,微生物底物)的足够量(例如浓度),以使LNAPL和DNAPL的降解如预期那样得到增强。 任何本发明的方法可以涉及用一种或多种特定物质(尿酸,电子受体,微生物底物,仅作为几个实例)修饰地下水,以增强DNAPL,也可能涉及LNAPL降解。
