The role of aerobic bacteria in the biodegradation of petroleum hydrocarbon contaminated groundwater was investigated in this study. A nutrient-treated groundwater sample was compared to an untreated water sample. At day 56, the percentage elimination of total hydrocarbon content in the water treated with nutrients and the untreated water sample (natural attenuation) was 89 and 74, respectively. The number of total heterotrophic and total hydrocarbon-using bacteria rose over time in all experimental samples. Bacillus sp., Arthrobacter sp., Micrococcus sp., Pseudomonas sp., Alcaligenes sp., and Flavobacterium sp. were among the bacteria isolated. At the end of day 56, the total petroleum hydrocarbon in water samples treated with nutrient and untreated water sample decreased from 15.33955 mg/L to 3.90361 mg/L and 9.49634 mg/L, respectively. At day 56, the physicochemical assessments were within the World Health Organization's drinking water standard. The aerobic bacteria found in the water samples used total petroleum hydrocarbons in laboratory contaminated groundwater; however, treatment with nutrient resulted in better elimination of the hydrocarbon pollutants.
