Environmental Strategy | Landfill Superfund Site
Working on behalf of the Potentially Responsible Party Group (the Group), including the the client, we initially provided third-party review of the Record of Decision (ROD) for the Landfill. Based on our review, Verdantas was hired by the Group to amend the remedial approach. We subsequently guided the project team through multiple Pre-Design Investigations (PDIs; see below) that were used to support a Source Control Focused Feasibility Study (SCFFS) to provide a summary of the new information from the PDIs and compare remedial alternatives. The SCFFS provided the basis to move forward with the Source Control (SC) Remedial Design and implementation. We currently interface with the regulatory agencies and acting as an intermediary in negotiations.
Achievements
NEGOTIATIONS WITH USEPA AND NHDES – Reviewed innovative remedial technologies that resulted in an Amended Record of Decision (AROD) and Explanation of Significant Difference (ESD) to document the change in remedial strategy. This allowed the PRP Group to modify the SC remedy and remove the cap requirement.
SUCCESSFULLY DESIGNED AND CONTSTRUCTED SC REMEDIAL ACTION – Completed 30 Percent to 100 Percent SC Remedial Design to implement groundwater extraction (GWE) at the toe of the Landfill to reduce contaminant migration. Observed construction and pilot testing of the 45 extraction well GWE system start-up and performed operation and maintenance activities during the initial years of operation.
FOCUSED ASSESSMENT AND REMEDIATION – Implemented PDIs in multiple areas of the site to identify a hot-spot in the Landfill to target focused remedial efforts, including soil vapor extraction and air-sparge. PDI activities included assessment of ecological impacts and sediment toxicity testing, evaluation of “hot spots” within the landfill, evaluation of the migration and fate and transport of a leachate plume downgradient of the landfill, and evaluation of potential soil vapor intrusion into nearby residences.

Project Details
TECHNICAL CONSULTING AND FIELD INVESTIGATION ACTIVITIES – We were part of a technical consultant team that successfully petitioned the USEPA to amend the original ROD for the Site. Based upon field investigation activities completed by the project team and subsequent negotiations with the regulatory agencies, the USEPA issued an AROD and ESD that changed the original low‑permeability landfill cap remedy to a permeable landfill cap with GWE remedy.
PROJECT PLANS FOR PDI ACTIVITIES – Based upon the AROD, we developed and implemented project plans for completing PDI activities at the Site, including a Site Management Plan (SMP), Health and Safety Plan (HASP), and Quality Assurance Project Plan (QAPP). The SMP and HASP provided guidelines for site operations, security, personal protective equipment, and site logistics. The QAPP governed how data would be collected, providing Standard Operating Procedures, data management requirements, and data validation procedures.
DESIGN AND CONSTRUCTION OVERSIGHT AND REPORTING – Verdantas provided oversight for design and performance of laboratory treatability and limited preliminary field studies confirming initial evaluation of bioremediation, air sparging, and in situ treatment trench remedial evaluations and reviewed deliverables describing the results of these studies. We reviewed design and construction of the demonstration bioremediation and air sparging treatment systems, performed oversight of its implementation, and assisted in the preparation of deliverables documenting the findings.
ANNUAL DATA COLLECTION AND EVALUATION – On an on-going basis since 2011, Verdantas manages annual monitoring requirements identified in the Revised Environmental Monitoring Program (REMP)/Groundwater Management Permit (GMP) at the landfill Site. Data collected includes annual water elevations from over
200 monitoring wells, groundwater quality data collected from approximately 50 monitoring wells, and surface water quality data collected from nearby surface water bodies. Annual activities include a review of the landfill surface to evaluate for locations of erosion and need for additional soil amendments.
TECHNICAL SUPPORT AND SCOPE OF WORK NEGOTIATIONS – We provided technical support of the Remedial Design/Remedial Action (RD/RA) Consent Decree and scope of work negotiations with the USEPA, United States Department of Justice, and NHDES. We also reviewed and evaluated a Remedial Investigation and Feasibility Study (RI/FS) to provide technical comments for the PRP Group regarding remedy design, evaluation, selection, and implementation.
QUARTERLY AND ANNUAL REPORTING – Verdantas prepares quarterly progress reports summarizing Source Control and Management of Migration groundwater extraction operational data and REMP activities. Source Control GWE system data includes total flow and annual testing of 45 extraction wells. Annual data is summarized in the Annual Remedy Performance Report that includes data validation, trend analysis, and analysis of the distribution over time.
EMERGING CONTAMINANTS – Verdantas is monitoring emerging contaminants for possible inclusion into the REMP program. 1,4-dioxane has been incorporated into the annual program and will likely be identified as a Constituent of Concern (COC) using an ESD. For PFAS evaluation, Verdantas prepared a Sampling and Analysis Plan; collected background, source area, and plume area groundwater samples to evaluate the extent of potential impact; and is currently negotiating with USEPA regarding continued monitoring approaches and requirements.
PUBLIC PRESENTATIONS – Verdantas participates in public meetings for the project on an as-needed basis and over the time of our involvement with the project (20 years), has attended and participated in numerous public meetings with the Cities, NHDES, USEPA, and members of the public. Verdantas considers public participation a fundamental component of the project and we routinely play a critical role as “translator” and “interpreter” conveying highly technical and complex investigation and regulatory information to the PRP Group, municipalities, and citizens.

When the former Caraustar-Rittman Paperboard facility was operating at its peak, the plant was home to more than 1,200 local employees. Its closing in 2006 resulted in the loss of these jobs and left behind 300-acres of vacant real estate in the industrial core of Rittman, Ohio.
The City of Rittman (Wayne County, Ohio) now has 80 acres of prime industrial property ready for a new end user and a new 205-acre public park that will be open to visitors next year. The redevelopment of the former Caraustar-Rittman Paperboard manufacturing facility is a monumental accomplishment achieved through an ambitious public-private partnership and state funding.
This large and complicated project involved close coordination with the City of Rittman, Wayne County, JobsOhio, Team NEO, Ohio EPA, Ohio Public Works Commission, Wayne County Health Department, and the Ohio Department of Transportation. Funding assistance, a critical factor to this project’s success, was provided through a $2 million JobsOhio Revitalization Program grant and a $2.5 million Clean Ohio Conservation Fund grant.
Redevelopment and revitalization of the former Caraustar-Rittman Paperboard facility is a classic example of how a public-private partnership can provide a solution for a civic problem. Preparing this property for new industrial and commercial development is needed for the economic viability of the community. Preparing the remaining property considered less desirable from a development perspective into public open space will preserve important habitat while offering health, wellness, and educational benefits for local residents and visitors for generations to come.

Verdantas has provided a wide range of environmental consulting services on an as-needed basis to the City of Philadelphia since 2014 and prior to that from 2001-2005. Working with the Department of Public Property required interaction with numerous agencies within the City, such as the Philadelphia Zoo, Parks and Recreation, the First Judicial District (Courts), the Philadelphia Redevelopment Authority, the Streets Department, the Water Department, and the Department of Commerce. With our cost-conscious, practical approach toward managing projects and solving problems, along with our talented team of engineers and scientists, over 400 work orders were completed during the recent contract. The Department of Public Property recently selected Verdantas to continue to provide environmental consulting services for the period of 2018 through 2021.
