Chemical Oxidation Overview and Chemical Oxidation Overview and Overcoming Regulatory BarriersOvercoming Regulatory Barriers

Defining in situ chemical oxidation

General applicability

Regulatory review

13

What is What is In Situ Chemical Oxidation?In Situ Chemical Oxidation?

Definition: A technique whereby an oxidant is introduced into the subsurface to chemically oxidize organic contaminants changing them to harmless substances Rapidly emerging technology Still subject of academic research as well as applied

routinely as a commercialized process Several options for selection of oxidant chemicals Requires good understanding of contaminant and site

characteristics to ensure effective treatment

14

Advantages and Advantages and Disadvantages of ISCODisadvantages of ISCO

Advantages Fast treatment (weeks to

months)

Temporary facilities

Treatment to low levels

Effective on some hard-to-treat compounds

Disadvantages Requires earlier spending

commitment

Involves handling powerful oxidants, and carries special safety requirements

15

General Applicability of ISCOGeneral Applicability of ISCO

ISCO has been successfully used in every state

Addresses organic contaminants Including hydrocarbons,

pesticides, and PCBs

Addresses contaminant phases High soil/groundwater

concentration Standard application

Low soil/groundwater concentration

Possible, but may not be cost-effective

Mobile NAPL (free product) Applicable, but requires more

knowledge/control Residual NAPL (sorbed)

Applicable, but requires a high oxidant dose

16

Regulatory ApprovalRegulatory Approval

How it used to be Inconsistent, bureaucratic permitting Resource Conservation and Recovery Act

(RCRA) often caused delays Fear of liability on the part of contractors, stakeholders, etc.

Today Underground Injection Control (UIC) program

To protect drinking water Resource Conservation and Recovery Act (RCRA) Comprehensive Environmental Response, Compensation and

Liability Act (CERCLA) Emergency Planning and Community Right to Know Act (EPCRA)

17

State Regulatory State Regulatory RequirementsRequirements

States that require an Underground Injection Control (UIC) permit/registration include AL, CT, DE, FL, GA, KS, LA, MD,

MO, NE, NV, NH, NJ, NM, NC, OK, OR, RI, SC, WV, WY

All other states require other approvals See Table 4-1: Regulatory

permitting requirements for oxidant injection by state

18

Regulatory Review of Regulatory Review of ISCO ProposalsISCO Proposals

Remediated to applicable groundwater remediation standard

Ensure that the injection Will not cause the plume to migrate

Will not create adverse vapor impacts

Is of sufficient volume to get the job done, and if not, that additional round(s) of injection will be necessary

Additional injectant-specific requirements would apply, depending on contaminant and injectant

19

Regulatory Review of ISCO Proposals: Regulatory Review of ISCO Proposals: Effectiveness of Remedial ActionsEffectiveness of Remedial Actions

Groundwater elevation contour maps

Graphs of contaminant concentrations over time

Summary of the volume of soil/groundwater treated

Summary of contaminant concentrations above/below applicable remediation standards

Generic evaluation criteria regarding the effectiveness of active soil and groundwater remedial actions

20

Regulatory Review of ISCO Proposals: Regulatory Review of ISCO Proposals: Performance-based Evaluation Performance-based Evaluation

If contamination continuously decreases, even after the injectant is used up Natural attenuation mode Post-treatment monitoring for at least 8 quarters

If concentrations rebound soon after the injectant is used up, it does not necessarily mean the technology has failed – need to continue monitoring to determine if: Concentrations continue to rebound Concentrations stabilize Concentrations decrease
