“…Oil can be transported by wave and tide-induced circulations into the beach sediments where it can be attenuated by natural biodegradation. Physical remediation efforts (e.g., manual scrubbing, pressure spraying) are also often able to remove large amounts of oil from shallow beach sediment [Owens et al, 2008].…”

“…However, in some cases oil has been found to infiltrate and persist in beach sediments for decades after an offshore spill [Owens et al, 2008;Li and Boufadel, 2010]. This tends to occur at beaches where there is a high permeability upper layer (i.e., gravel) that is underlain by a low permeability layer.…”

“…The upper layer is able to temporarily store the oil until it penetrates into the lower layer where it becomes entrapped by capillary forces and biodegradation is limited due to the reducing conditions in the low permeability sediment Li and Boufadel, 2010]. In this way, oil is able to persist in the beach sediment until there is a change in environmental conditions (e.g., storm event) that leads to erosion of the shoreline [Owens et al, 2008]. Recent numerical simulations by Geng et al [2015] and Geng et al [2016b] illustrated the important role of tide-induced circulations, nearshore groundwater flows and chemistry in the 43 shallow nearshore aquifer (i.e., availability of nutrients and dissolved oxygen) in controlling the aerobic biodegradation of residual oil in tidally-influenced beaches.…”

Sustainable coastal resource management requires sound understanding of interactions between coastal unconfined aquifers and the ocean as these interactions influence the flux of chemicals to the coastal ocean and the availability of fresh groundwater resources. The importance of submarine groundwater discharge in delivering chemical fluxes to the coastal ocean and the critical role of the subterranean estuary (STE) in regulating these fluxes is well recognized. STEs are complex and dynamic systems exposed to various physical, hydrological, geological, and chemical conditions that act on disparate spatial and temporal scales. This paper provides a review of the effect of factors that influence flow and salt transport in STEs, evaluates current understanding on the interactions between these influences, and synthesizes understanding of drivers of nutrient, carbon, greenhouse gas, metal and organic contaminant fluxes to the ocean.Based on this review, key research needs are identified. While the effects of density and tides are well understood, episodic and longer-period forces as well as the interactions between multiple influences remain poorly understood. Many studies continue to focus on idealized nearshore aquifer systems and future work needs to consider real world complexities such as geological heterogeneities, and non-uniform and evolving alongshore and cross-shore morphology. There is also a significant need for multidisciplinary research to unravel the interactions between physical and biogeochemical processes in the STE, as most existing studies treat these processes in isolation. Better understanding of this complex and dynamic system can improve sustainable management of coastal water resources under the influence of anthropogenic pressures and climate change.

“…Bioremediation of these toxic and xenobiotic compounds has gained deserved attention during the last decades, mainly because of the accidental spills and leakages occurring at different locations worldwide (Swannell et al 1996). Even if a decontamination process is carried out soon after a spill occurrence, the persistence of oil may continue even for decades in shorelines, as it was demonstrated by some well studied oil spill cases, threatening the inhabiting species (Owens et al 2008). During accidental spills, removal or remediation of the contaminants is usually taken into account right away.…”

Bioaugmentation and biostimulation strategies to improve the effectiveness of bioremediation processes

2010

Bioremediation, involving bioaugmentation and/or biostimulation, being an economical and eco-friendly approach, has emerged as the most advantageous soil and water clean-up technique for contaminated sites containing heavy metals and/or organic pollutants. Addition of pre-grown microbial cultures to enhance the degradation of unwanted compounds (bioaugmentation) and/or injection of nutrients and other supplementary components to the native microbial population to induce propagation at a hastened rate (biostimulation), are the most common approaches for in situ bioremediation of accidental spills and chronically contaminated sites worldwide. However, many factors like strain selection, microbial ecology, type of contaminant, environmental constraints, as well as procedures of culture introduction, may lead to their failure. These drawbacks, along with fragmented literature, have opened a gap between laboratory trials and on-field application. The present review discusses the effectiveness as well as the limitations of bioaugmentation and biostimulation processes. A summary of experimental studies both in confined systems under controlled conditions and of real case studies in the field is presented. A comparative account between the two techniques and also the current scenario worldwide for in situ biotreatment using bioaugmentation and biostimulation, are addressed.

“…In general, spilled oil degraded with several factors such as evaporation, diffusion, photooxidation, and biodegradation Laffon et al 2006;Michel and Hayes 1999;Owens et al 2008;Taylor and Reimer 2008). In tropical areas, because of strong sunshine, high temperature, and frequent storms, spilled oil is expected to degrade faster than in the temperate and boreal areas although it still is poorly studied.…”

Following the oil spill accident of the Solar I tanker in 2006 off the coast of Guimaras Island in the Philippines, polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs in some aquatic organisms were investigated at Luzaran in Guimaras and Taklong Islands, which were heavily polluted with spilled oil, immediately and 1 month after the accident. The concentrations of total PAHs were 11.9-52.3 ng/g dry weight in fish. Meanwhile, total PAH concentrations in shellfish were 38.0-3,102 ng/g dry weight in Luzaran and 128-236 ng/g dry weight in Taklong. Pyrene, phenanthrene, and fluoranthene were dominant in most fish and chrysene in all shellfish. Significantly higher concentrations of all alkylated homologs were detected in shellfish than in fish. These differences had two possible causes, that is, the differences between fish and shellfish could be attributed to the uptake routes and/or their metabolizing abilities.
