The objective of this program was to quantitatively |
|
assess the effectiveness of in situ electrolysis of |
|
groundwater on the growth of soil microorganisms. The |
|
electrolysis method was used to supply oxygen to soil |
|
microorganisms to enhance bioremediation of sites that |
|
are contaminated with hydrocarbons. Electrochemical tests |
|
were performed with two different types of soils in a 10- |
|
gallon glass container. Experimental variables examined |
|
included driving voltage, current, and electrode spacing. |
|
Stainless steel mesh was used for both the anode and the |
|
cathode. Depending on the soil, a sustained supply of |
|
dissolved oxygen up to 16 ppm was achieved. The |
|
population of soil microorganisms increased with |
|
increasing the oxygen content in the groundwater. A |
|
slight decrease in the population was seen at the |
|
cathode, which might have been due to an increase in the |
|
pH at the cathode. |
