Accuracy, Productivity, Efficiency: GIS Use in Site Redevelopment

EnviroAnalytics Group (EAG) was faced with the task of managing data for the investigation and re-development of a 3,000 acre former steel mill property. The project was expected to generate data from thousands of soil and groundwater samples for thousands of analyses. To further complicate data management, EAG needed to be able to analyze the data for different development scenarios on over 30 different parcels as the property was subdivided for development, and to do these analysis within the schedules required to facilitate leasing decisions.

EAG had ARM Group (ARM), as part of their scope for investigation and risk assessment for the project, design and build a Geographic Information Systems (GIS) to manage the data and to facilitate visualization, analysis, interpretation, and display of geospatial data to identify, understand, monitor and communicate the relationships, patterns, and trends of location based data.

As a result of working with multiple agencies and stakeholders, many revisions were required throughout the preparation of the Investigation Work Plans, the Phase II Investigation Reports, risk assessments, development scenarios, and ultimately, Response and Development Work Plans. Manual data entry and static images were replaced by automated data inputs to a database, reducing the potential for errors, while database queries were used to directly populate georeferenced figures and data tables, the boundaries of which could be changed in real time with minimal effort. This process allowed for efficient and timely evaluation of alternative remediation and development scenarios to feed into development decisions. The GIS has been an invaluable tool in all aspects of the project, from characterizing historical plant features for investigation planning, to streamlining the transfer of data from the laboratory, to querying and visualizing the data to identify issues and to communicate with all parties.

The utilization of GIS information technologies to manage, interpret and present data associated with large scale investigation and remediation projects improves the efficiency and accuracy of data evaluation and reporting, making it possible to meet the evolving demands and often tight schedules of the redevelopment process in an efficient and cost-effective manner.
