First blank choices- bioremediation, incineration, air sparging

Second blank - nitrogen, carbon dioxide, oxygen.

Answer 1

Answer:

first blank - bioremediation ; second blank - oxygen

Explanation:

Bioventing is a process of stimulating the natural in situ biodegradation of contaminants in soil by providing air or oxygen to existing soil microorganisms. Bioventing uses low air flow rates to provide only enough oxygen to sustain microbial activity in the vadose zone.

Answer 2

Answer:

bioremediation, oxygen

Explanation:

Bioventing is a type of bio remediation process in which contaminant is biodegraded by providing oxygen to organism of soils. This activates the activities of microorganisms and stimulates the natural biodegradatiion of hydrocarbons in soil.

Bio venting is used in soil which is contaminated by fuel or chemicals.
