“…With this setting, it is an area vulnerable to hurricane and winter storm surges. While hurricanes can cause severe damages as we have witnessed in recent years by Hurricanes Katrina (e.g., Pardue et al, 2005;Adams et al, 2007;Stout et al, 2007;Suedel et al, 2007), Rita (e.g., Rego & Li, 2009a, b, 2010a, Gustav, and Ike (Li et al, 2009, the effect of winter storms (cold fronts) cannot be neglected because of the much higher frequency of occurrence and its cumulative effects (e.g., Roberts et al, 1987;Moeller, et al, 1993;Walker & Hammack, 2000;Pepper & Stone, 2004;Feng & Li, 2010). The hydrodynamics can significantly influence the sediment transport (e.g., Cundy et al, 2007) and wetland stability (e.g., Valdemoro et al, 2007).…”

“…Numerous studies have been conducted on contaminant concentrations and toxicity measurements in New Orleans and Lake Pontchartrain immediately following the hurricane (Presley et al 2006;Cobb et al 2006;Van Metre et al 2006;Adams et al 2007;Stout et al 2007;Liebl et al 2008;Shi et al 2010;Abel et al 2010). In general, concentrations of organic contaminants (such as polycyclic aromatic hydrocarbons (PAHs), pesticides, and polychlorinated biphenyls) decreased in the months following the storm, although few concentrations were detected above the EPA's Human Health Medium Specific Screening Levels (Van Metre et al 2006;Liebl et al 2008).…”

Hurricanes are relatively frequent ecological disturbances that may cause potentially long-term impacts to the coastal environment. Hurricane Katrina hit the Mississippi Gulf Coast in August 2005, and caused a storm surge with the potential to change the trace element content of coastal surface sediments. In this study, surface estuarine and marine sediments were collected monthly following the storm from ten sites along the Mississippi Gulf Coast (Mobile Bay, Grand Bay Bayous Heron and Cumbest, Pascagoula, Ocean Springs, Biloxi Gulf, Back Biloxi Bay, Gulfport Gulf, Gulfport Courthouse Rd, and Gulfport Marina). Concentrations of V, Cr, Mn, Fe, Co, Ni, Zn, As, Cd, and Pb were measured by inductively coupled plasma-mass spectrometry to evaluate their temporal and spatial variations in the year following Hurricane Katrina. Sediments were characterized by pH, particle size distribution and total carbon and nitrogen content. Trace element contents of the sediments were determined in both <2 mm and <63 μm grain size fractions. Results revealed no significant temporal and spatial variability in trace element concentrations, in either size fraction. Potential ecological risk of the sediments was assessed by using NOAA SQuiRTs' guideline values; most concentrations remained below probable adverse effects guidelines to marine organisms suggesting that trace elements redistributed by Hurricane Katrina would not cause an adverse impact on resident organisms. Instead, the concentrations of trace elements were site-dependent, with specific contaminants relating to the use of the area prior to Hurricane Katrina.

At sites impacted by volatile organic compounds (VOCs), vapor intrusion (VI) is the pathway with the greatest potential to result in actual human exposure. Since sites with VI were first widely publicized in late 1990s, the scientific understanding of VI has evolved considerably. The VI conceptual model has been extended beyond relatively simple scenarios to include nuances, such as biological and hydrogeological factors that may limit the potential for VI and alternative pathways, such as preferential pathways and direct building contact/infiltration that may enhance VI in some cases. Regulatory guidance documents typically recommend initial concentration-or distance-based screening to evaluate whether VI may be a concern, followed by a multiple-lines-of-evidence (MLE) investigation approach for sites that do not screen out. These recommendations for detailed evaluation of VI currently focus on monitoring of VOC concentrations in groundwater, soil gas, and indoor air and can be supplemented by other lines of evidence. In this Critical Review, we summarize key elements important to VI site characterization, provide the status and current understanding, and highlight data interpretation challenges, as well as innovative tools developed to help overcome the challenges. Although there have been significant advances in the understanding of VI in the past 20 years, limitations and knowledge gaps in screening, investigation methods, and modeling approaches still exist. Potential areas for further research include improved initial screening methods that account for the site-specific role of barriers, improved understanding of preferential pathways, and systematic study of buildings and infrastructure other than single-family residences.
