The Determination of Sediment Polycyclic Aromatic Hydrocarbon (PAH) Bioavailability using Supercritical Fluid Extraction (SFE) and Ultra-Trace Porewater (UTP) Analysis 

The Humphreys Engineer Center Support Activity (HECSA) 

ENSR is performing services under a 2-year ESTCP (Environmental Security Technology Certification Program) project. 

Introduction:

The Environmental Security Technology Certification Program's (ESTCP) goal is to demonstrate and validate promising, innovative technologies that target the most urgent environmental needs of the Department of Defense (DoD). These technologies provide a return on investment through cost savings and improved efficiency. The current cost of environmental remediation and regulatory compliance in the Department is significant. Innovative technology offers the opportunity to reduce costs and environmental risks.  ESTCP offers funding in the following four focus areas: Environmental Restoration, Munitions Management, Sustainable Infrastructure, and Weapons Systems and Platforms.

Objective:

This project will demonstrate the ability to use site-specific estimates of polycyclic aromatic hydrocarbon (PAH) bioavailability in sediments to accurately predict toxicity to benthic organisms in a marine environment. Specific objectives include (1) use supercritical fluid extraction (SFE) and ultra-trace porewater (UTP) analyses to estimate the bioavailability of PAHs in marine/estuarine sediments collected from two Department of Defense (DoD) facilities, (2) compare the predicted toxicity of the impacted sediments using these bioavailability data and the Environmental Protection Agency (EPA) narcosis model to the actual measured toxicity of the sediment to a macroinvertebrate, and (3) develop technical and regulatory guidance for the management of PAH-impacted sediments, guidance that incorporates use of the SFE and UTP site-specific estimates of PAH bioavailability for predicting toxicity, assessing risk, and making more informed sediment management decisions.

Technology Description:

The sediment characterization protocol to be demonstrated uses estimates of the bioavailability of PAHs to predict sediment toxicity and characterize risk to benthic aquatic life. This protocol uses SFE and UTP to estimate site-specific PAH bioavailability and the EPA hydrocarbon narcosis model to predict the resulting sediment toxicity. SFE relies on mild supercritical carbon dioxide to extract the rapidly released PAHs from sediments. The UTP is a sensitive technique for measuring low concentrations of dissolved PAHs in sediment porewater. The chemical concentrations reported by both SFE and UTP are used as input values for the EPA hydrocarbon narcosis model, which predicts the toxicity of the PAH mixtures to benthic organisms. The concentration of rapidly released or porewater PAHs will be compared to macroinvertebrate toxicity. In addition, the carbon types within the sediment samples will be characterized to support a mechanistic interpretation of the observed bioavailability and toxicity data.

Expected Benefits:

Use of the sediment characterization protocol is expected to lead to more accurate assessments of sediment toxicity and risk and the establishment of less conservative, site-specific remedial objectives. Accurate assessments of PAH bioavailability also will support improved evaluations of the efficacy of the remedial strategies that have been identified by EPA in their recent guidance for sediment remediation at hazardous waste sites. Further use of the protocol will improve management of residual risk after the completion of monitored natural recovery, active/passive capping, and dredging of sediments and during the evaluation of beneficial reuse alternatives for dredged sediments. Technical and regulatory guidance will be provided on the measurement and use of site-specific estimates of PAH bioavailability for characterizing sediment toxicity and the ecological risk associated with contaminated sediments.
