Presentation and Publication Opportunities

Posted By Tamara L. Sorell, Monday, March 07, 2016

Lisa Richman of MOE has proposed a session that she has asked me to co-chair on Monitoring to be held  at the next Battelle Sediments conference "Ninth International Conference on Remediation and Management of Contaminated Sediments" Jan.  2017 in New Orleans.

http://www.battelle.org/media/conferences/sedimentscon

As more sites move into the remedial phase, appropriate monitoring to  assess endpoints and effectiveness is increasingly critical.  We invite everyone to consider submitting an abstract for this great conference.

In addition, in my capacity on the editorial board of Current Pollution Reports, I am  always seeking articles on sediments.   CPR  is a relatively new Springer journal and publishing is a wonderful opportunity to get your ideas and name out there.  Please do not hesitate to contact me if you have any ideas for an article and I'll be happy to give you some specifics.

http://www.springer.com/environment/pollution+and+remediation/journal/40726

Finally let me know if anyone is planning to be in Nantes ( I will not be, regrettably)  Currently I do not know if we have an Advisory Group meeting set up (Stuart?) but I can look into it if there are a few of you who would like to meet up.  If you prefer to organize something something less formal you can use this blog to do it, and please do report back to the whole group on any outcomes.  

Thank you!

Sediment Risk Management

Posted By Tamara L. Sorell, Friday, February 26, 2016

As we discussed late last year and at the SETAC meeting in Nov., we are kicking off a Work Group under the Sediment Advisory Group to address the risk management side of things.  A number  of you have previously  expressed an interest in this topic and have been already contacted via e-mail.   I will be sending this same post to the Ecological Risk Assessment AG (ERAAG) so I apologize for the duplication if you are subscribed to both.    

I’d like to get this moving and set up a call for March.  There are a variety of aspects we could pursue and I thought once we have a working team we can set up calls, webinars, and surveys to solidify our group objectives.

 

Possible topics:

·        Establishment of Remedial Action Objectives (qualitative)

·        Development of clean-up goals (quantitative)

·        Integration of risk into remedial alternative/technology evaluation

·        Attainment of long-term risk objectives

·        Establishment of monitoring objectives

·        Development and implementation of monitoring programs

 

Possible Work Group products:

·        Sponsor/organize SETAC Global meeting sessions and presentations

·        Coordinate or promote sessions with other organizations (SETAC chapters, Battelle sediments, SRA, SWMG, etc.,); in particular an ASTM Task Group for Sediment Corrective Action has kicked off.  I have joined this team and plan to participate remotely.  We should be aware of what they are doing and see if we can dovetail or integrate our activities. 

·        White papers

·        Journal articles

·        Technical guidance (probably a bit ambitious)

·        Workshops

·        What else?

Iron in Sediments

Posted By Trudy Watson-Leung, Wednesday, September 23, 2015
Updated: Wednesday, September 16, 2015

An inquiry about what research is being done on iron in sediments was posed to the Science Advisory Group listserve and it seemed like a valid question to pose to the Sediment Advisory Group as well.  Some of the responses that have been recieved so far are below.  I hope this information will be useful to some of you and if you have anything to add please reply to this blog.    

 

From Thomas Seal from FDEP Water Quality Assessment Program:

The Florida Depart of Environmental Protection's Watershed Monitoring program has hundreds of iron results from lake sediments throughout the state, collected from both large and small lakes for over ten years now.  We use the element iron, as well as aluminum, to normalize our trace metal data, thus ruling out those samples that are naturally higher in trace metals due to their higher clay (hence Al and sometimes Fe) content. 

 

The freshwater sediment normalization tool is available at this website....

 

http://www.dep.state.fl.us/water/monitoring/fwseds.htm

 

The freshwater sediment normalization tool was developed for FDEP under contract with a private dredging and engineering firm in Jacksonville, Taylor Engineering.  But the employee who mainly developed it (Dr. Steven Schropp) worked for FDEP in the early 1990s before he was hired by Taylor.  We have a companion tool for the state’s estuarine sediments (Windom and Schropp 1988) , but to develop that tool we did not collect iron data, only aluminum.

 

If you want to see the FDEP iron data, please contact Thomas Seal (Thomas.Seal@dep.state.fl.us) or Aisa Ceric.

 

From Ed Swain of the Minnesota Pollution Control Agency:

 We surveyed over 100 shallow freshwater systems in Minnesota, and measured iron both in porewater and bulk sediment for our study on how sulfate is converted into hydrogen sulfide, which can be toxic to wild rice.  Our interest is in the iron that is available to detoxify porewater sulfide through precipitation of relatively insoluble FeS compounds.  So, rather than quantify sediment iron with a strong acid digestion, we estimated redox-active iron by a 30-minute extraction with relatively weak HCl (0.5 N).  We modeled the net conversion of sulfate in surface water into porewater sulfide via structural equation modeling, which found that conversion of sulfate to sulfide is limited by sediment TOC, presumably because sulfate-reducing bacteria are limited by the availability of organic matter.  The net concentration of sulfide in porewater is then controlled by the availability of redox-active iron in the bulk sediment (we found that the concentration of porewater iron had little predictive power; porewater iron is less than 1% of the redox-active iron in the bulk sediment).

 

Our draft proposal for protecting wild rice from excess sulfate can be found at:

http://www.pca.state.mn.us/r6wxpf9

 

From Tom H. Gries, NEP QA Coordinator for the Environmental Assessment Program:

I did a quick search of Ecology's EIM database.  There are 1000's of records associated with analyses of iron in samples of both freshwater and marine/estuarine sediments.

Records may reflect slightly different matrices (e.g., stormwater sediments) or methods.  And I noticed different units of measure.  But they're readily available: http://www.ecy.wa.gov/eim/index.htm

 

From Steven Bay of the Toxicology Department Southern California Coastal Water Research Project:

We include iron in our analyte list for our regional monitoring program and thus have hundreds of data points for southern California marine and estuarine waters.  We have used the data previously to develop regression relationships to normalize other metal concentrations to account for natural background.  Haven't done any spiked toxicity studies with iron.

Invitation to Participate on Spiked Sediment Toxicity Database Working Group

Posted By Trudy Watson-Leung, Monday, June 29, 2015

SEDAG Members:

 SEDAG has initiated a project to develop an open access and collaborative database of toxicity data from test using chemical-spiked sediment.  We had some initial discussions regarding this project at the November 2014 Vancouver SEDAG meeting and several SEDAG members expressed interest in participating in the effort (either to develop the database structure or to contribute content).  

I would like to continue this process and work with interested members to develop a draft version of this database over the next few months.  We are planning to hold a series of web meetings/conference calls over the next two months to develop this idea into a product for review by SEDAG at a future meeting.  

If you would like to participate in these meetings to develop the design, please send me an email with your contact information by Friday, July 3.  

I will then follow up with the respondents to schedule an initial  2-hour web meeting in mid-July.  This first meeting will discuss the scope of the project and identify a process/schedule for moving forward.

 Please send you responses directly to me at  steveb@sccwrp.org by July 3.

 Thanks for your support of this project,

 Steve

******************

Proposed session associated with the SETAC Sediment Advisory Group for SETAC North America in Salt Lake City, Utah on Nov 1 to 5, 2015


1. Design and Use of Spiked Sediment Toxicity Tests to Improve Environmental Management Decision Making. Sediments play a key role in determining fate and effects of most environmental contaminants. Laboratory toxicity tests with spiked sediments are used to investigate these processes and inform decisions for managing the environmental risk from both marine and freshwater systems. Researchers attracted to this session will present advancements in the design and use of spiked sediment toxicity testing, as well as results of studies that improve our understanding of the effects of specific contaminants or geochemical factors on aquatic life. Presentations will include: sediment spiking methods and exposure characterization, use of results for remedial decision making, assessing the influence of mixtures and confounding factors, and application of spiked sediment tests to assess ecological risks from “Contaminants of Emerging Concern” (e.g., pesticides, pharmaceuticals, and algal toxins) and those associated with more historical toxicants (e.g., metals, PAHs). Chairs: Steve Bay, Southern California Coastal Water Research Project (Steveb@sccwrp.org, 714-755-3204) and Lisa Taylor/Environment Canada (Lisa.Taylor@ec.gc.ca, 613-991-4062)


2. The Continuing Evolution of Sediment Toxicity methods and Data Interpretation. Sediment toxicity laboratory methods have undergone refinement and evolution over the course of the last few decades. These methods were initially developed by multiple organizations with varying objectives making standardization of the methods a challenging endeavor. There are currently a number of acute and chronic sediment toxicity methods as well as methods to assess bioaccumulation of chemicals using both freshwater and marine organisms. Methods have historically been used to assess the toxicity of field-collected sediment samples or the effects of a specific chemical through dosed sediment exposures. Due to the complex nature of these methods, there is a need to refine some of the standard methods to improve the consistency, reproducibility and quality of the results. The general goal of this session will be to present research on the refinement of current methods for conducting laboratory sediment toxicity tests, development of new methodology and discuss challenges in test conduct as well as data interpretation. Potential presentation are as follows: (1) methods for culturing or collecting test organisms, (2) effects of testing variables on organism performance, (3) results of inter-laboratory testing with a focus on chronic methodology using midge, (4) evaluation of toxicity identification evaluation data (5) alternate taxa or alternate toxicity endpoints (6) challenges in analyzing sediments for chemical specific concentrations and (7) interpretation and use of test results from a regulatory standpoint. Chairs: Christian Picard (Smithers Viscient, Wareham MA, cpicard@smithers.com, 508-295-2550), Chris Ingersoll (USGS, Columbia MO, cingersoll@usgs.gov, 573-876-1819) and Curtis Eickhoff (Maxxam Analytics , Burnaby, BC, CEickhoff@maxxam.ca, 604-638-5033)


3. Bioaccumulation in Management and Regulation. The purpose of this session is to feature new scientific knowledge in the area of bioaccumulation that can improve the management and regulation of environmental contaminants. The session will present new bioaccumulation studies, as well as applications of existing knowledge with the purpose of improving environmental management and regulation. This session has been designed to present research that advances the science of bioaccumulation or applies bioaccumulation science and models to improve management and regulation of human health and ecological risks from water and sediment contaminants. Chairs: Doris Vidal-Dorsch (dorisv@sccwrp.org) and Frank Gobas (gobas@sfu.ca).


4. Risk Management of Sediments. This session is intended to bring together presentations about how advances in risk, sustainability, and remediation tools have been or can be integrated into management decisions at contaminated sediment sites. Recent guidance documents describe sophisticated sediment assessment and remediation techniques, including sustainable approaches, but provide little or no specificity on how they can be incorporated into remedial action objectives (RAOs) and remediation goals (RGs). Sophisticated assessment results may be difficult to apply quantitatively, and back-calculated risk-based clean-up goals are often unrealistically low, not attainable, or not sustainable. There are few formal sediment quality standards, and screening levels do not make appropriate risk management objectives. Therefore, sediment management decisions are typically site-specific and vary widely among sites. This session kicks off a new SETAC Sediment Advisory Group (SEDAG) work group that will address the integration of recent advances in risk, sustainability, and remediation tools into risk management decision making at sediment sites. Topics of interest include development of RAOs; calculation of RGs using human health risk models, ecological risk food chain models, bioassay/sediment toxicity dose-response information, and non-bulk sediment endpoints (such as pore water); sediment remediation technologies such as conventional tools (removal, capping), innovative technologies/pilot studies (such as in situ stabilization), and combined approaches; development, implementation, and advances in remedy effectiveness monitoring; risk communication and stakeholder engagement; and regulatory trends and precedents in sediment management. Chair: Tama Sorell, tsorell@brwncald.com)


5. Groundwater-to-Surface Water Interface (GSI) Investigations for Sediment Characterization and Ecological Risk Assessment. For contaminated sites adjacent to water bodies, the environmental impact of site-related contaminant releases to aquatic habitats, including contaminated groundwater to surface water discharges, have become key assessment components of site investigations. Consequently, regulatory attention to groundwater-to-surface water interface (GSI) investigations, and related influences on ecological risks, has increased significantly in recent years. While the most common focus for GSI investigations is shallow sediment pore water collection for transport verification and exposure estimation/risk assessment, GSI studies also require a keen understanding of the entire transport pathway and a refined conceptual site model. Therefore, GSI investigations are interdisciplinary endeavors that require an integration of a variety of technical expertise (for example, hydrogeology, analytical chemistry, ecotoxicology, and unique sampling techniques). This session will offer an opportunity to display: the latest pore water sampling techniques; GSI transport pathway analyses; the integration of GSI data into ecological risk assessments; and/or the use of complimentary investigation components that enhance GSI understanding (for example, benthic community assessments, exposure estimates, hyporheic profiling). This session will also be a venue to review investigation case studies and experiences and gain insight into regulatory opinions on GSI investigations and related studies for use in site investigations. Chairs: Dan Lavoie/CH2M HILL (Daniel.Lavoie@CH2M.com, 202-265-2906) and Tim Canfield/USEPA (Canfield.Tim@epa.gov, 580-436-8535)
