Conceptual Site Model

Strategy Development
Complexities require a strategy that is based on total project goals: Business objectives Regulatory and Stakeholder objectives Short- and long-term goals
Continually re-assessed and forward looking Continually discussed with Management and
Regulators

Client Strategy What is the Business Strategy?
Operating property or Legacy Site Is there Insurance?
Many clients and regulators do not have sediment-specific technical expertise
Previous Owners Adjacent properties (PRPs) and are you
aligned? What is timing?
Can investigations be combined with new- or re-development?
Is property for Sell?

Study Design – Strategic Planning
What are the Questions Being Asked by the Agencies? How Do We Answer the Questions?
How to Define and Agree on Objectives? How Sophisticated are the Data Needs?
What Are the Sources/Pathways? How many do you assess at once?
What Are the Ranges of Successful Outcomes?
![Page 8: Strategic Planning for Contaminated Sediment Projects: Setting the Course for Proper Project Execution Howard L. Cumberland Geosyntec Consultants October](https://reader035.vdocuments.net/reader035/viewer/2022062412/5a4d1aff7f8b9ab0599860e5/html5/thumbnails/8.jpg)
Data Needs
Multiple Pathways and contaminant sources (site and non-site related)
Source identification Nature and extent of contamination – horizontal and
vertical Contaminant fate and transport Hydrodynamics and hydrology Exposure pathways and biological receptors FS data needs Remedial Options CONTINUALLY ADD DATA AND RE-EVALUATE
CSM

Formulate the Study Questions
What level of contamination is a concern, and over what area?
What are the Sources? What are the unknowns? What do you need to know in order to make
decisions about how to clean up or manage the site?
What are the perceptions of the agencies? What are the receptors? Are there Published/Accepted sediment risk
criteria? What might be the end game?
