Reviewer Question

ESTCP is currently testing several terrestrial pipe locating and characterization technologies at the Edison NJ test bed. Explain how this project will leverage that work to refine the methodology and technology selection.

Why It Matters

The pre-proposal already names the US EPA Lead Service Line Identification Test Bed at Edison as the calibration and validation site, and it proposes bench-scale sensor screening before buried-condition testing. Reviewers are asking this effort to build on work already underway there, not to repeat terrestrial sensor-selection experiments independently.

This is the first research phase because Edison results can constrain Q01, Q03, sensor down-selection, terrestrial baseline, standoff experiments, and cost assumptions.

Decomposed Research Questions

  • What technologies have already been evaluated at Edison?
  • What sensor classes and, if public, which vendors?
  • What test configurations, burial conditions, and materials were used?
  • What performance measures and terrestrial baselines exist?
  • What findings, datasets, lessons, and known limitations are public?
  • What ESTCP demonstrations are ongoing, and are project leads or contacts publicly listed?
  • What should this project not repeat?
  • How can Edison results refine sensor down-selection, test methodology, the material test matrix, the terrestrial baseline, standoff experiments, Go/No-Go criteria, cost assumptions, and the UAV comparison method?

Required Outputs

  • Evidence records for public EPA and ESTCP sources, with conditions preserved.
  • A statement of what has already been learned, what should not be repeated, what terrestrial baseline already exists, and which sensors deserve further consideration.
  • An explicit leverage plan for the full proposal: build on, do not duplicate.
  • No assumption that Edison work supports a result that has not been reviewed.

Current Working Hypotheses

These are hypotheses, not findings.

  • Task 1 vendor screening should be narrowed by published Edison and ESTCP results rather than started from a blank sensor list.
  • Task 2 should add controlled standoff and a comparison to an existing terrestrial baseline, not re-prove basic buried detection if that baseline already exists.
  • UAV work remains downstream of that terrestrial baseline.

Supporting Evidence

  • EVID-0001 — Edison facility, seven sections, contacts
  • EVID-0002 — 2024 EPA method-class snapshot, including GPR and EMI readiness labels
  • EVID-0003 — ESTCP EMI project, Phase 1 at an EPA test bed
  • EVID-0004 — secondary confirmation that Phase 1 was at Edison
  • EVID-0005 — second ESTCP EMI project; Edison not named
  • EVID-0006 — ESTCP acoustic project; Edison not named
  • EVID-0007 — ESTCP topic named GPR and EMI as examples
  • EVID-0008 — EPA TA page corroborates Edison and collaboration

Findings

  • FINDING-0001 — public-record map only; not a performance finding

Decisions

  • DECISION-0001 — proposed. Name Edison and EW25-8806; do not cite unpublished Phase 1 metrics.

Q04 second pass did not obtain the 2024 EPA review PDF or the EW25-8806 Phase 1 report.

Experiments Required

None assigned. Public sources still leave Task 2 standoff and Task 3 UAV motion unmeasured. See Archived source: retained internally.

Open Gaps

  • EPA 2024 technology-review report not obtained.
  • No public EW25-8806 Phase 1 metrics or dataset.
  • Edison as-built diameters and exact depths not public.
  • Whether EW25-8486 or EW25-8604 used Edison is unknown.
  • No public ESTCP GPR LSL demonstration page found.
  • No public UAV, elevated-standoff, or fusion results from Edison.

Proposal Sections Affected

  • Related Efforts
  • Technical Approach, Task 1 and Task 2
  • Demonstration Sites
  • Technical Risks
  • Sensor down-selection and Go/No-Go criteria

Ready-for-Proposal Test

This question is adequately answered when the proposal can name the relevant Edison or ESTCP work, state what this project will use from it, state what it will not repeat, and identify the remaining measurements this project must still perform.

Status

Researching. First-pass public map exists. Not proposal-ready: no terrestrial performance baseline, no accepted leverage decision, and no proposal language.
