SmartData for the Environment2002 Columbia Technologies

Subsurface Imaging using DPT Rigs, Sensor Technology and Onsite Analysis Tools

Direct Sensing Technology

A fundamentally better approach for mapping the subsurface

For Brownfields, Property Transfers, NPL sites and TRIAD Projects


The Problem

• Heterogeneity is the norm• Most investigations are not defensible

– Too few samples– Samples are not representative

• Sampling error supercedes lab error• Most clean-up efforts fail

A much larger number of data points are required to reduce uncertainty.


Managing Uncertainty

• EPA’s TRIAD Approach– Systematic Planning– Real Time Measurements– Dynamic Work Plans

• The 7-Step Data Quality Objective Process


SmartData SolutionsTM

A comprehensive approach integrating recent advances in:

• Sensor technology

• Rapid computational analysis

• Interactive 3D webcasts



We can now quickly and reliably:• Provide comprehensive images of the

subsurface.• Manage uncertainty and assess risk.• Avoid downstream failures and costs.• Monitor remediation performance.• Obtain more cost-effective closure.


3D Image of Solvent Spill Produced from MIP Profiles



SmartData - A continuous stream of chemical and physical data, available in a geo-referenced,

digital and user-friendly format.

Use it for the 3D imaging of subsurface• sources, • pathways, • soil types • remediation effectiveness

Integration with other site data, such as: • Constituent-specific data from discrete samples• Physical features from surface and subsurface


Advantages of SmartData?

• Large amounts of geo-referenced, digital data that can be rapidly reviewed, processed, posted and displayed for real time analysis and decision making.

• Data that is easily correlated and cross-checked with other data.


Types of SmartData

• The MIP/EC Probe for Fuels and Solvents– Membrane Interface Probe/ Electrical Conductivity– MIP/CPT

• LIF/UVIF – SCAPS/ROST/FFD for Fuels– Laser Induced or UV Fluorescence +/- MIP– LIF/CPT

• Range of Emerging Tools


Membrane Interface and Conductivity Probe

• For detecting LNAPL, DNAPL,dissolved phase and gas phase VOCs.

• For locating sources and plumes in vadose and saturated zones, in sands and clays.

• For locating hydrologic and geologic units.• For assessing risk of mass transport. • For monitoring treatment effectiveness


MIP Downhole Probe

• Heated probe • Semi-permeable

membrane• Contaminant vapors

partition into a carrier gas

• Transported to FID, PID, & ECD detectors at the surface

• Results are displayed in real-time on a lap-top computer.


Direct Sensing MIP/EC


Multiple Platforms

• Direct push rigs• CPT units• Drill rigs• Waterborne• All-terrain track• Indoor – limited

access


Smarter Sensors Broader Data


MIP Response vs Lab


Where are you going to sample?


SmartData SolutionsTM Investigation Strategy

• Use MIP/EC to obtain detailed logs of site.• Generate comprehensive 3-D image. • Then select “more fully representative”

discrete samples for analysis.• Make decisions, focus

monitoring/treatment and close sites, based on the “whole picture”.


MIP results vs water data


SmartData SolutionsTM Site Assessment Benefits

• Fewer but better sample and monitoring well locations.

• Stop endless investigations!

• Prevent/limit the big problem sites.

Minimum MIP-PID Response

Note the plume appears unbounded at these locations


Same Site - plume based on limited lab results

DPT Sample Results Color indicates BTEX concentration in ug/L

BTEX plume based on DPT results – less resolution


SmartData SolutionsTM Risk Assessment

• Calculate contaminant mass per hydrogeologic unit

• Determine mass available for migration

• Determine risk from available mass

• Assess monitoring options vs remedial options per hydrogeologic unit


SmartData SolutionsTM Risk Assessment Benefits

• Provide adequate basis for RBCA.

• Remove Regulator’s uncertainty.

• Increase confidence in fate and transport modeling with more data density.


3D Image of MIP Data v Well Data


SmartData SolutionsTM Remediation Strategy

• Use detailed MIP and EC data to assess risk and, if needed, to focus treatment.

• Clearly differentiate available mass.• Target units with available mass.• Monitor treatment effectiveness with

second MIP survey.
