Title: Pore Water Sampling Methodologies, Applications, and the Road to Commercialization

Abstract: Passive pore water sampling approaches are recognized as one of the best tools to quantify the availability of contaminants in sediment, surface water, and soil. Despite dozens of publications detailing the development and application of passive sampling approaches, recent enthusiastic regulatory support (e.g., USEPA’s 2012 passive sampling guidance), and a 6-paper series detailing a successful 2012 SETAC Pellston workshop on passive sampling, widespread application by the end-user community (i.e., industrial and government organizations, consultants) progresses slowly for this powerful technology.

This presentation will provide an overview of pore water sampling approaches for various analytical types (metals, organics) highlighting actual field deployments at contaminated sites. For each approach, real and perceived barriers to widespread application of passive sampling will be presented from an end-user’s point of view. Attention will be paid to practical lessons learned from environmental consultant’s experiences in applying passive sampling techniques and strives made to advance commercial availability of the approach. Additionally, we will discuss where the field of passive sampling needs to trend in the next few years to maximize the adoption of passive sampling approaches in the end-user community. With this perspective of future trends in mind, current research and opportunities will be discussed along the lines of transferring technologies from academic and research application to more widespread commercial availability. Despite the current challenges and research action items, currently-available passive sampling approaches are coming on the market for widespread application and can provide high-quality data to aid environmental decision makers.

Title: New advances in passive sampling for sediment risk assessment

Abstract:  Risk assessment in polluted sediments is confounded by unpredictable sorption behavior of sediment components. For hydrophobic organic contaminants (HOCs), the freely dissolved concentration in sediment porewater used in conjunction with an appropriate model has been shown to be an excellent predictor of sediment toxicity, bioaccumulation in benthic organisms, and flux into the overlying water. Recent developments in passive sampling has been able to overcome the challenge of accurate measurement of the freely dissolved concentrations and affords the opportunity for a paradigm shift from traditional practice that can reduce uncertainty in risk assessment and bolster confidence in the science used to support management of contaminated sediments. This presentation will provide an overview of the science behind passive sampling of hydrophobic organic compounds in water, a practical guidance on the use both in-situ and ex-situ, and some of the remaining challenges in the application of passive sampling. The presentation will provide links to resources available to a practitioner to apply passive sampling at a field site and work through the process of using the measurements for risk assessment. The presentation will end with a couple of case studies of passive sampling, one in

the field used to assess progress of an in-situ remedy, and the other on assessing exposure pathways to fish based on laboratory exposure studies.

Title: A Comparison of SPME Approaches for the Analysis of Alkylated PAHs in Pore Water

Abstract: Total PAH concentrations in sediment are generally recognized in the literature to be poor predictors of benthic invertebrate toxicity. Porewater analysis provides a better indication, however the direct measurement of PAH concentrations in pore water has traditionally been very challenging. This paper reviews two approaches, one fixed laboratory and one passive sampling, for the pore water analysis of the EMAP 34 PAH list using solid phase micro extraction (SPME). The fixed base laboratory method has been codified as ASTM Method D7363-13a, “Determination of Parent and Alkyl Polycyclic Aromatics in Sediment Pore Water Using Solid-Phase Micro- Extraction and Gas Chromatography / Mass Spectrometry in Selected Ion Monitoring Mode”. This procedure only requires a small volume of pore water, which is separated from the bulk sediment by centrifugation and then subjected to a flocculation step to assure that only the truly dissolved fraction is determined. The sample is then analyzed by GC/MS-SIM with a SPME sample introduction technique. The passive sampling approach utilizes SPME fibers which are deployed in the sediment for a set period of time, then collected and analyzed in the laboratory for the EMAP 34 PAHs. The relative benefits and drawbacks of each approach are discussed.

Title: Modern Models for Predicting Partitioning, Bioconcentration, and Toxicity of Organic Chemicals: The End of the Age of Octanol

Abstract: Predicting contaminant partitioning to environmental phases and bioconcentration and toxicity to plants and aquatic organisms continue to be central problems in environmental chemistry and engineering. Contaminant fate is largely determined by the extent to which contaminants partition from the aqueous phase to colloidal, suspended, sediment, and soil particles. Trophic transfer is determined by the extent that they accumulate in plants and animals. Contaminant effects are modeled by the extent to which they bind to receptor sites in biota. Many of the models use the octanol-water partition coefficient (KOW) as the sole chemical descriptor. They relate the parameters of interest, e.g. the organic carbon-water partition coefficient (KOC), the organism lipid-water partition coefficient (BCF) and the concentration that causes 50% mortality (LC50) to KOW. The degree of success and their wide spread use are testimony to their success when applied to the class of compounds for which they were developed.

However, as the classes of compounds that need to be modeled has expanded from the non-polar hydrophobic chemicals, for which the equations using KOW are based, to more polar, more soluble compounds, the model predictions exhibit systematic bias and larger errors. A newer

6| P a g e

class of models based on the Abraham model of solvation will be presented. This model explicitly considers hydrogen bonding, polarization interactions, van der Waals interactions and cavity formation. Models for predicting KOC for both particulate and dissolved organic carbon; BCF for fish and grasses; and polar narcosis LC50s will be presented to evaluate the extent of improvement over the KOW based models. Methods for estimating the Abraham parameters which utilize only the molecular structure will also be discussed.

Title: Monitoring Pore Water and Water Column PAH Concentrations in the Intertidal Environment Using Passive Sampling Methods

Abstract:  Passive sampling for pore water constituents is a topic of great interest amongst regulators, industry, and academics. Passive sampling techniques, including POM, PE, and PDMS, directly measure the freely dissolved concentration, which is proportional to chemical activity and therefore an accurate measurement of the freely dissolved concentration is necessary for risk assessment, determination of transport mechanisms, and ultimately improved management of contaminated sediment sites.

One of the applications most suitable for passive pore water sampling is sediment cap monitoring as part of remedy performance assessments. This talk will focus on the development and use passive samplers for assessment of cap performance at several contaminated sediment sites across the country. Discussion will be centered around the use of PDMS samplers at remediated sediment sites such as Chattanooga Creek, Eagle Harbor, and the West Branch of the Grand Calumet River. The use of performance reference compounds (PRCs) to determine the fraction of steady state achieved during a sampling period, an important step in estimating the freely dissolved contaminant concentration, will also be discussed. Volatile losses of low-molecular weight compounds was addressed at the Eagle Harbor sight and accounted for in the sampling design.

The presentation will offer insight into the applications of this research for various purposes, demonstrate the utility of passive pore water sampling for remedial monitoring, and discuss the coupling of pore water data with ecological receptors.

Title: Porewater: NJDEP Site Remediation Program Regulatory Perspective

Abstract: This presentation will focus on the utilization of porewater sampling consistent with the NJDEP Site Remediation Programs Technical Requirements for Site Remediation and Ecological Evaluation Technical Guidance. As new technologies emerge in the realm of ecological risk assessment, the regulatory agencies must keep pace with these technologies to ensure they are being utilized appropriately. This presentation will discuss the NJDEPs views on porewater sampling as a tool to help quantify ecological risk, support post-remedial monitoring programs, and identify future regulatory needs.

Title: Use of pore water in conjunction with other biotic and abiotic datasets to evaluate remedial success in a freshwater river environment

Abstract:  Mercury was used between 1929 and 1950 at a textile manufacturing plant in Waynesboro, Virginia, and was released and transported into surface water, sediments, soils, and biota of the South River. Legacy mercury from the plant accumulated in depositional areas along the river and floodplain, including riverbanks. Changes in hydrology and land use practices have resulted in erosion of these deposits and remobilization of the associated mercury, making it available for methylation.

Bank stabilization was evaluated as a potential remedial strategy to eliminate or reduce the introduction of mercury adsorbed to soil particles associated with bank erosion. A 500-ft long pilot bank stabilization project was constructed to test this hypothesis. The pilot was intended to assess whether control of mercury loading to the water column and sediment through eroding banks would result in reduction of mercury concentration in biotic and abiotic aquatic media. Mercury concentrations in several biotic (Asiatic clams) and abiotic (sediment, pore water) media were measured pre- and post-stabilization. Substantial reductions in mercury concentration were documented across all media types during the first post-stabilization monitoring event. This presentation will focus on the utility of pore water monitoring to document remedial success in a changing aquatic environment.

Title: Application of In-Situ Porewater Technology at a Contaminated Sediment Site to Assess Recontamination from VOC and PCB-Impacted Groundwater

Overview. While the use of in-situ passive samplers to characterize contaminated sediments has been established, passive samplers are still a relatively new technology, and questions on data interpretation and unit conversion continue to arise. Our team recently demonstrated the successful usage of polyethylene (PE) passive samplers at a Superfund site to measure porewater

8| P a g e

VOC and PCB concentrations. Presentation will focus on the application of PCB performance recovery compounds (PRCs) in the passive sampler to calculate PCB porewater concentration and unusual behaviors observed with the PRCs from a discharging chlorinated solvent plume that impacted PCB partitioning into the samplers.

Background/Objectives. The site (or brook) is located in New Jersey and flows past a former capacitor- manufacturing facility. The brook and wetland floodplain soils have been impacted from discharging groundwater that is contaminated with chlorinated solvents (primarily TCE and DCE) and a dissolved-phase PCB load. Two types of passive samplers were deployed in the brook to assess the PCB and VOC porewater concentrations, estimate a contaminant flux, and evaluate the potential ecological and human health risks associated with the observed porewater concentrations. The uncertainty in the PCB porewater concentration was estimated by examining the PRC surrogates, which were added to the sampler to assess equilibrium conditions.

Approach/Activities. Two passive samplers were deployed in the field (one for VOC porewater and one for PCB). While the VOC porewater concentrations were assumed to be in equilibrium after 2 weeks, PCB porewater concentrations were estimated based on equilibrium partitioning equations between the aqueous phase and the polyethylene media. PCB PRCs (isotope labeled surrogates) are added to the PCB passive samplers to shorten deployment times by allowing the mass transfer coefficient to be gauged and modeled. For our samplers, eight PRCs were impregnated into each passive sampler prior to deployment. The presence of a discharging chlorinated solvent plume appears to have impacted the partitioning of the PCB targets into the passive samplers, based on evaluation of remaining PRC surrogates in the samplers.

Results/Lessons Learned. A field survey (conducted prior to deployment) using water quality measurements to locate the discharging chlorinated plume will be discussed. Benefits of impregnating passive samplers with a suite of PCB PRCs will be discussed, along with the three combinations of PRC surrogates that were ultimately used to estimate PCB porewater concentrations. The unusual PRC behaviors, while making it harder to quantify porewater concentrations, were informative with respect to identifying either water with high VOC co-solvent content or porewater that was exfiltrating quickly. Both the VOC and PCB passive samplers aided the project by delineated in the stream where contaminated groundwater was discharging and providing porewater VOC and PCB concentrations and mass flux estimations.

Title: Site Specific Partitioning and Bioavailability Assessment for Sediments from South Wilmington Wetlands

Abstract: PAHs and PCBs are listed as the chemicals of potential ecological concerns for South Wilmington wetlands. The objectives of this study were to evaluate the site specific porewater concentration and sediment partitioning constants for PAHs and PCBs using polyethylene passive samplers, and to assess the site-specific bio-concentration factor (BCF) through a 4-week laboratory PCB bioaccumulation in freshwater invertebrates (L. Variegatus). Results were used to refine the sediment preliminary remediation goals (PRG) based on two ecological receptors: benthic invertebrates and Sandpiper.

9| P a g e

For PAHs, the site specific sediment partitioning constants (Koc) were 1-2 orders of magnitude higher than the generic values used in preliminary risk assessments, which resulted in higher revised PRGs than initial ones based on the protection of benthic invertebrates. The estimated PRG based on benthic exposure is more restrictive compared to exposure to the Spotted Sandpiper as PAHs do not bio-magnify and primarily pose problems for benthic invertebrates.

For PCBs, nearly 1 order of magnitude higher site-specific Koc was observed than generic values. Bioaccumulation of PCBs in worms followed the typical behavior and was in agreement with generic correlations for organism uptake, which could be largely explained based on PCB sediment porewater concentration. For PCBs, ecological exposure to the Spotted Sandpiper resulted in a more restrictive PRG compared to benthos based PRGs.

Overall, site-specific assessment of PAH and PCB partitioning in sediments was able to fine tune risk assessment for the South Wilmington Wetlands and develop more appropriate PRGs that reflected true exposure of the contaminants to ecological receptors.

About the Delaware/Raritan Greenway Land Trust R.W. Johnson Education Center

(http://www.drgreenway.org/missionhistory.html)

D&R Greenway Land Trust is central New Jersey's nonprofit land preservation organization, founded in 1989 through the collaboration and vision of four organizations: the Stony Brook - Millstone Watershed Association, Friends of Princeton Open Space, Regional Planning Partnership, and the Delaware & Raritan Canal Commission. Founders, including Jim Amon, Rosemary Blair, Dennis Davidson, Sam Hamill, and Bob Johnston, realized that our region's open space was threatened with extinction. Their vision of an organization dedicated to the preservation of our remaining natural areas led to the creation of this small grassroots organization that completed the first nonprofit acquisition using Green Acres funds in 1992.

Originally named Delaware & Raritan Greenway, we changed our name in 2004 to better reflect our preservation work as a land trust, and to account for the expansion of our work beyond our traditional focus along the Delaware & Raritan Canal.

We permanently preserve watershed lands and large-scale landscapes, thereby preventing the loss of open space to development. Our operating region consists of over 1,500 square miles, encompassing portions of the Delaware, Raritan and Millstone River watersheds and the Delaware & Raritan Canal. This includes Mercer, Hunterdon, Somerset, Middlesex, Burlington and Monmouth counties. We have broadened our work to include preservation of farm land in Salem County in the area of Mannington Meadows.

We serve as the continuing steward on many preserves and easement lands. We lead the list of nonprofits in New Jersey to successfully complete land transactions with State Green Acres funds. In 2008, D&R Greenway worked in partnership with the New Jersey Department of Agriculture to preserve the 1,900-acre Seabrook Farm in Salem County. In 2009, two more farms around the Mannington Meadows were preserved. We have a staff of nine full-time and six part-time professionals. There are many volunteers working on various events and stewardship projects. In 2010, D&R Greenway closed on the 340-acre, St. Michael's property in Hopewell, New Jersey. D&R Greenway is working on-site to enhance the woods, meadows and fields for agriculture, native seed propagation, community gardens and wildlife habitat.

D&R Greenway Land Trust sponsors offer many exciting educational and professional programs at the Johnson Education Center, its home in Princeton. New Jersey.
