“…Human activities centered on oil production, transportation, and storage result in oil spillage into freshwater sources in the world.

With a widespread increase in contamination of water systems, effective contamination control and remediation is becoming a major technical problem (Mirzaee et al, 2017).…”

In this study research methods are assessed to determine the spatial distribution of petroleum hydrocarbon contamination in the coastal aquifers and to develop a groundwater flow and transport model that can be used to evaluate the level of natural attenuation that has occurred. The stages of this study include: 1) preliminary assessment and conceptual model including hydrogeologic characteristics of the site, the history of the site, and any past or current remedial activities, 2) field and laboratory investigations including soil and groundwater sampling techniques such as soil borings, multi-level monitoring well installation, aquifer tests and water quality sampling. Parameters to be measured, their measurement methods and use of these data should be explained in detail, 3) physical and geochemical characterization of the study area with the results of the field and laboratory investigations, 4) development of the groundwater model with selected software, 5) evaluation of monitored natural attenuation according to primary and secondary lines of evidence established during the investigation. The primary lines of evidence, which is a stable or shrinking plume rather than an expanding plume, will be the benzene, toluene, ethylbenzene and xylene (BTEX) contour maps prepared as a result of the groundwater sampling. Secondary lines of evidence, which include geochemical data that serve as indicators of naturally occurring biodegradation and estimates of natural attenuation rates, will be based on electron acceptor/reduction product concentrations measured within the BTEX plume. The results of the groundwater modeling are used to help decide whether the monitored natural attenuation process results in BTEX contaminant levels declining to acceptable levels within a specified time. If projections of contaminated levels indicate that natural attenuation is not enough for remediation, then additional remedial alternatives can be recommended for further investigation.
