Abstract

The pollution of groundwater by gasoline near gas stations is commonplace and cannot be fully avoided despite awareness of the risks and implementation of preventative measures. In the past few decades, several aqueous oxidants such as permanganate and persulfate have been employed to remediate such pollution. Research in this field has mostly focused on the use of oxidants in the typical environments encountered in Europe and North America, namely fresh groundwater at a temperature of about 10°C. In this study, bench experiments were carried out to investigate the effectiveness of persulfate (PS) as an oxidant to remediate petroleum hydrocarbons in a saline environment at a higher temperature of 30°C; such as groundwater typically encountered in Saudi Arabia. The target organic compounds investigated were Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX).
