web-based Environmental Data Management System

1. webEDMS Expedites Site Cleanup and Closure

• It seamlessly converts island of project Data Information Knowledge Solution on the fly
• web-EDMS functionalities (e.g. real-time data acquisition, trending analysis, 3D visualization and risk assessment) provide complete and current site information to the project team that help them
  • understand complex site conditions
  • identify impediments to site closure
  • reach consensus on remedial approach and plan
  • perform real-time health risk assessments to guide site activities and ensure acceptance of the site End State
  • provide transparency to RI/FS activities and earn trust of regulatory agencies and the general public

2. Data Islands Exist in Site Cleanup and Closure

3. webEDMS Connects Data Islands and Generates Synergistic Value

5. 2D Data Analysis & Trending Interpretation

webEDMS: GIS Maps webEDMS links site data, documents and related information to its unique (x,y,z) User simply clicks an object on the map and its related data is shown (i.e. object analysis) webEDMS: Object Analysis (1) Perform analysis on individual objects on the fly Compare to regulatory standards View results in a chart or spreadsheet Colored coded trend plots created dynamically webEDMS: Object Analysis (2) View results in a spreadsheet All collected data on an object is indexed and can be exported in seconds for report preparation webEDMS: Object Analysis (3) Compare site data to regulatory standards or user-defined values Display query results (> threshold levels) spatially on site maps Color-coded results on map for easy trending interpretation This photo shows hot spots are all within site boundaries Multiple Levels of Notification If conc. detected exceeds pre-set level, warnings are immediately sent Continuous alerts until acknowledged or mitigated Keep responders and project staff fully informed Email, voice, and/or text notification

6. 3D Visualization of Site Conditions

All Data Can Be Shown Visually Build common ground within the project team Time periods of sampling results can be specified This shows a limited time frame of samples webEDMS Allows Easy Partitioning of Site Data by Time and Geographic Area Here is a much longer time frame of sampling Much more data is shown here Data related to any selected geographic areas can be selected for analysis webEDMS: 3D Visualization Visualize site conditions in 3D View well casing, soil lithology View sample concentrations webEDMS: Plume Conditions (1) Display plume conditions based on area, cleanup level selected Calculate size, volume of impacted area New threshold conc. renders new shape of plume webEDMS: Plume Conditions (2) Dissecting plume vertically and horizontally to identify impediments to site closure and see effects of the hot spots Calculate size, volume of impacted area New cross section renders new impacted areas webEDMS: Region of Interest Create Region of Interest (ROI) of any shape Perform analysis on ROI (plume size, shape, risk assessment) on the fly Select Multiple Regions of Interest Create multiple ROIs View, compare subsurface conditions simultaneously View plume extents relative to individual ROI Display individual ROI attributes Instantly calculate health risk associated with ROI selected Real-time identify impediments to site closure (major risk drivers) webEDMS: Aerial View of GW Contamination Create transparent view of plume by COC (compound of concern) Critical in understanding site conditions (plume size, shape, risk assessment) on the fly

7. Real Time Human Health Risk Assessment

The webEDMS Risk Assessment Assess Site Related Risk on the Fly The Risk Assessment is directly linked to central database Instantly calculates site risks based on user-specified site, receptor & exposure conditions User can identify any geographic area for focused risk assessment User can specify the medium of impacted and time frame of interest The webEDMS Risk Assessment Identify the Acceptable Site End State on the Fly Health risks associated with user defined conditions are calculated real time User can identify major risk drivers within the ROI and Develop the best remedial approach accordingly Details of Risk Calculation Are Saved Electronically for Paper Report It makes risk calculations transparent to laymen It builds trust w/ stakeholders Real time risk calculation saves time and money It provides much needed What-If management tools to the team

8. Benefits of webEDMS

web-EDMS is a powerful information sharing and communication tool that provides transparency to the entire RI/FS process, enhances project efficiency and quality, and streamlines regulatory reviews and approvals

Trust among stakeholders (agencies, the general public, and Responsible Party) is earned after solving issues together via transparent RI/FS processes

Once regulatory agencies understand and verify the results, they approve site cleanup and closure expeditiously

9. Use of webEDMS Can Help Speedup Cleanup & Lower Closure Costs
