Moving Mud - Remediating Great Lakes Contaminated Sediments 

INTRODUCTION  

From 1993 through 1996, the Great Lakes National Program Office (GLNPO) of the U.S. Environmental Protection Agency (USEPA) awarded $5,272,711 in grants for 34 projects to 14 State, Tribal, and Federal agencies and educational institutions to address contaminated sediments throughout the Great Lakes. 

The sediment grants program provides funding, technical support, and vessel support to assist contaminated sediment work in priority geographic areas, known as Areas of Concern (AOCs), in the Great Lakes. The 31 AOCs on the U.S. side of the basin are locations where beneficial uses are impaired for any one of 14 designated criteria. To address these beneficial use impairments, each AOC developed a Remedial Action Plan (RAP). All RAPs written to date have identified contaminated bottom sediments as a significant problem that must be addressed to attain beneficial uses. GLNPO’s emphasis and ultimate objective is to foster the remediation of contaminated sediments at these AOCs. The grants program was developed with the intention of continuing the efforts of the Assessment and Remediation of Contaminated Sediments (ARCS) Program, which was administered by GLNPO from 1987 to 1993. 

This document is a synopsis of GLNPO’s sediment grants program. The focus is on the 34 projects that have been initiated since fiscal year 1993. Included is a tabulation of grant recipients and monetary distribution, a summary of each of the projects, and a look ahead to the future of sediment assessment and remediation in the Great Lakes. 

In part because of the 34 projects, significant progress has been made towards the restoration of clean sediments in the Great Lakes: 

GLNPO's Sediment Assessment and Remediation Team has created this document as a yardstick, to measure not only where we have been, but how far we have to go. We congratulate our grantees for the ingenuity and dedication that they have exhibited. We hope that this document not only highlights the great work taking place right now, but serves as a catalyst for new and fresh ideas and a renewed effort to restore clean sediments, one of the building blocks of a healthy and vibrant Great Lakes ecosystem. 

PRESENT PROGRAM  

The U.S. Environmental Protection Agency's commitment to cleaning up contaminated sediments remains strong. Region 5's Agenda for Action lists contaminated sediments as one of six priorities for FY 1996 and 1997. In order to focus on the problem and to continue the work begun under the ARCS Program, GLNPO established the Sediment Assessment and Remediation Team in 1994. The mission of the Team is to reduce and prevent the impacts of contaminated sediments on the Great Lakes ecosystem. 

The Team's goals include the following: 

  1. Perform and provide support for sediment assessments throughout the Great Lakes.
  2. Provide support for sediment-based mass balance modeling activities.
  3. Provide support for sediment-based risk assessments.
  4. Provide technical support toward the selection and implementation of remedial alternatives.
  5. Foster partnerships among Great Lakes stakeholders to promote sediment clean-up activities.
  6. Have an active involvement in the setting of policy and direction for the Great Lakes contaminated sediment program.

In order to accomplish these goals, the Team works cooperatively with States, EPA Regions and other Federal agencies to help address contaminated sediment problems around the Great Lakes basin. We actively coordinate with the Region 5 Sediment Team and RAP and Lakewide Management Plans (LaMPs) activities to ensure resources are brought to bear on the most pressing contaminated sediment problems. 

We have also created a GLNPO Sediment Database, which will contain all of the sediment chemistry, toxicity, and benthos data generated as part of GLNPO-funded projects. The database, built in Microsoft Excel, employs a standard data reporting format for both field and laboratory data. This information will be available for dissemination to anyone interested. 

One of the major resources that GLNPO provides is the services of the R/V Mudpuppy. The R/V Mudpuppy is a 32-foot flat-bottom boat specifically designed for sediment sampling in shallow rivers and harbors. First used during the ARCS Program, the R/V Mudpuppy is now available to grantees for use during their projects, and to date has been used to perform sediment assessments at 19 Great Lakes locations (Figure 1).

The sediment grants program is a major tool used by GLNPO to address contaminated sediments. From 1993 through 1996, the Sediment Assessment and Remediation Team provided $5,272,711 in grants and Interagency Agreements for 34 projects to 14 State, Tribal, and Federal agencies and universities to assess and remediate contaminated sediments throughout the Great Lakes. Helping to bridge the gap between assessment and remediation, our FY 1996 funding included a specific focus on remediation demonstration grants. 

New projects are solicited each year when GLNPO issues to the Great Lakes community a Funding Guidance document which includes a request for preproposals. Contaminated sediments is one of the program areas that is targeted for financial support. Award criteria for sediment grants vary from year to year based on discussions with partners, results of previously-funded activities, and a desire to encourage innovative ideas. As site work progresses and assessments are completed, many AOCs are nearing the remediation phase. In keeping with this, current priorities for potential sediment projects can be considered in the following order: (1) on-the-ground cleanup, (2) remedial design, and (3) field work and assessment.

Note: Projects involving more than one lake basin are included for as many lake basins as applicable. 

Project Timetable 
The average project length is two years. For field projects, the first requirement of the project is creation of a quality assurance project plan (QAPP), which describes in detail the sampling design and laboratory analysis methods. This plan must be approved by sediment and quality assurance personnel from GLNPO. Aside from development of the QAPP, project activities generally include execution of the scope of work (e.g., the actual assessment or remediation), compilation of any data results, and production of a final report. 

Project Location 
Most contaminated sediments projects are local in scope, focusing on a harbor or stretch of river. This is true for 33 of the 34 projects discussed in this document. The exception, project #4, has a Great Lakes Basin-wide scope. 

Partners 
Many projects involve agencies or groups which act as partners to the grantee by providing technical advice or assisting with activities such as field sampling and data analysis. Table 8 provides a list of these partners.

Narrative 
Each summary contains a brief descriptive section which provides background information, highlights the purpose of the project, and often states the project goals and objectives. 

Table 9 shows the projects, represented by project #, grouped into five categories based on the type of work performed. Because sediment contamination at many AOCs was uncharacterized when the funding program started, the first few years have been dominated by assessment projects. Beginning in FY 1996 with the addition of the two remediation projects, we expect the ratio of assessment:remediation projects to continue to decrease in the coming years as AOCs are characterized and actions move toward remediation.

Data Results 
Twenty-five of the thirty-four projects include field sampling in their scope of work. For these 25 projects, a synopsis of the current state of the data results is provided. When the data results have been finalized, they are sent to the GLNPO Sediment Team and entered into the GLNPO Sediment Database, which will contain all of the sediment chemistry, toxicity, and benthos data generated as part of GLNPO-funded projects. 
The data is then made available for dissemination to any interested parties.

LESSONS LEARNED  

As our funding program has moved forward, discussions with our grantees have yielded valuable information as to what some of the hurdles are for remediation of contaminated sediments and restoration of a clean benthic environment. While assessments at several AOCs have been completed, the move to the next steps - remedial design and actual remediation, or `moving mud'- has not been easy. We recognize these difficulties and have focused our efforts on providing assistance in order to bridge these gaps. 

We believe that one of the primary keys to achieving successful remediation at any site will be the development of a strong and committed partnership of stakeholders. These individuals and organizations must be able to pool their resources and expertise as well as cooperate to overcome their differences. The Ashtabula River Partnership is a prime example of how a community has organized itself around a common goal of contaminated sediment remediation. We are encouraged by their dedicated efforts thus far, and we hope to soon see many other communities following their lead. 

Recommendations for Future Efforts 
GLNPO's Sediment Assessment and Remediation Team recommends that these goals be focused on in the future to address the contaminated sediment problem in the Great Lakes: 

Much progress has been made since the inception of the ARCS Program 10 years ago. Anticipating the next 10 years, we look forward to supporting the continuing and renewed efforts of our grantees as we all strive to reduce and prevent the impacts of contaminated sediments on the Great Lakes ecosystem. 

As our grants program continues and our database expands, we want to make sure we remain on the right track. Feedback from our partners and from the community is invaluable in helping us to do this. What are your thoughts and opinions about GLNPO's Contaminated Sediments Program? What questions do you have? How can the program be improved? 

We urge you to communicate with us.
