Abstract:Contamination of groundwater by petroleum hydrocarbons is a widespread environmental problem. This study focused on evaluating and quantifying the potential of natural attenuation of groundwater at a petroleum contaminated site in northeast of China. 11 rounds of groundwater sampling and subsequent chemical, microorganism analyses were performed during the 1 year monitoring period, and the mass flux technique was used to calculate the attenuation rates. The temporal variation of total petroleum hydrocarbons (TPH) concentrations suggested that the content of contaminants at this site has been decreasing with time, and characteristics of the groundwater geochemistry and microorganisms confirmed the expected occurrence of biodegradation via aerobic respiration, nitrate reduction and sulfate reduction, the calculated attenuation rates were between 0.0046-0.0064d-1, indicating the time to achieve the remediation goal at the contamination site was possible within 3 years by natural attenuation alone.
