Remediation System Design & Implementation

Presented by


Remediation

Remediation

  • For the purpose of this presentation, remediation is assumed to be any mechanical means of removing or reducing petroleum hydrocarbon mass in the subsurface.


Remediation1

Remediation

  • is a means to an end


Remediation2

Remediation

  • is the process by which an NFA is achieved


Remediation3

Remediation

  • is the “end” is No Further Action


Remediation4

Remediation

  • Prerequisites for a comprehensive remedial system.

    • Site Conceptual Model

    • Feasibility Study

    • Pilot Test

    • Design and Construction


Site conceptual model

Site Conceptual Model

  • Critical to effective system design, installation and operation

  • Minimum data package:

    • Source area definition

    • Geologic and groundwater framework

    • Historic liquid level data

    • Soil and groundwater concentration data; with vertical, horizontal and temporal coverage

    • Boring logs and well diagrams

    • Cross sections


Site conceptual model1

Site Conceptual Model

  • Additional model data should include:

    • Summary of receptors

    • State regulatory compliance targets

    • Risk-based clean up concentrations


Site conceptual model2

Site Conceptual Model

  • Definition of remedial goals

    • Set remedial technology target concentrations for:

      • Source zone, with respect to horizontal and vertical profiles

      • Down-gradient locations; i.e. property lines, water wells, other receptors


Site conceptual model3

Site Conceptual Model

  • Define source area and required treatment zones


Feasibility study

Feasibility Study

  • Minimum elements

    • Survey all potentially applicable technologies

    • Include preliminary cost comparisons over life-cycle

    • Evaluate impact on site features

    • Evaluate with respect to remedial goals


Pilot tests

Pilot Tests

  • The purpose of a pilot test is to generate sufficient high-quality data around which to design an efficient remediation system.


Pilot tests1

Pilot Tests

  • Example Pilot Test Flow chart


Remediation5

Remediation

  • System Design & Construction


Remediation6

Remediation

  • System Design & Construction

    • Inspect system construction details prior to delivery


Remediation system installation

Remediation System Installation

  • Logistics to complete include power drops


Remediation system installation1

Remediation System Installation

  • Subgrade infrastructure – extraction piping details


Remediation system installation2

Remediation System Installation

  • Subgrade infrastructure – should provide sufficient control

  • for air flow

  • liquid flow


Remediation system installation3

Remediation System Installation

  • Subgrade infrastructure – extraction wellhead assembly; adjustable drop-tube


Remediation system installation4

Remediation System Installation

  • Subgrade infrastructure – extraction wellhead assembly; adjustable drop-tube advantages


Remediation system installation5

Remediation System Installation

  • Site-Specific Issues

    • Overhead Utilities

    • System Enclosure Locations

  • Site-specific application

    • Infrastructure additions:

      • Extraction wells

      • Sparge points

      • Observation points


Remediation system startup shakedown considerations

Remediation System Startup & Shakedown Considerations

  • Equipment break in

  • Process “debugging”


Remediation system startup shakedown considerations1

Remediation System Startup & Shakedown Considerations

  • Adjustments for site specific factors

    • Post pilot test findings

  • System balancing

    • Flow rates: liquids, vapors, hydrocarbons


Operational phase

Operational Phase

  • Vital Elements for Successful Remediation

    • Effective performance

      • Run Time

        • Common causes of system shutdowns - Power outages

Simple fix: add alarm callout routine to PLC after power is restored


Operational phase1

Operational Phase

  • Vital Elements for Successful Remediation

    • Effective performance

      • Run Time

        • Common causes of system shutdowns – Sediment filters

  • Simple fix: install additional filter housings


Operational phase2

Operational Phase

  • Vital Elements for Successful Remediation

    • Effective performance

      • Run Time

        • Common causes of system shutdowns – Pump failure

  • Simple fixes: add wye strainer (sediment filter) to pump inlet. Clean float control switches


Operational phase3

Operational Phase

  • Vital Elements for Successful Remediation

    • Targeted application

      • SCM

        • Treatment zone

        • Vertical extent of remediation

        • Horizontal extent of remediation


Operational phase4

Operational Phase

  • Vital Elements for Successful Remediation

    • Effective monitoring; timely & accurate

      • Run Time

      • Mass Removal

      • ROI

      • Quarterly Groundwater Sampling Results

      • Confirmation Soil Sampling Results
