NWI ELF/EMF Occupational Health Pilot

Hammond × Unilever × West Lake Corridor × SBDC × Purdue

Measure first, keep the claims narrow, and make the result useful to Hammond employers.

1. Why this pilot now

South Shore Line says Monon Corridor service on the West Lake Corridor began March 31, 2026.[1] Unilever's Hammond Dove Bar Soap Factory is an active Hammond site.[2] The business question for Hammond owners is simple: can a low-cost baseline study help decide whether any follow-on action is worth funding?

For owners

Measure before spending on fixes.

For workers

Track whether the new corridor setting creates a measurable exposure baseline.

For funders

Produce a clean dataset that can support a follow-on grant decision.

2. What we know

Established

In this pilot, EMF means the broader non-ionizing category — including Wi-Fi, Bluetooth, and power systems — while the pilot itself focuses on ELF magnetic fields from power systems, not UV or X-rays.[3][4] IARC evaluated extremely low-frequency magnetic fields as Group 2B, possibly carcinogenic to humans.[4] That is a cancer-risk signal, not proof of harm at a specific site.

Mixed / inconclusive

A 2016 systematic review in Science of the Total Environment (doi: 10.1016/j.scitotenv.2016.03.065) found reported associations between low-frequency noise and infrasound with annoyance, sleep-related problems, concentration difficulties, and headache in some populations, but the studies were heterogeneous and not causal proof.[5] A 2023 randomized double-blind crossover study in Environmental Health Perspectives (doi: 10.1289/EHP10757) found no detectable adverse effects after 72 hours of simulated wind-turbine infrasound versus sham exposure.[6]

So the defensible statement is simple: measure first; do not overstate symptom causation.

That is enough to justify a measurement study, not a verdict.

3. Guardrails

No claim of diagnosis, therapy, or causation. Phase inversion, if ever tested, remains an exploratory HYPOTHESIS — not a proven product or treatment. No DNA resonance claims without an exact frequency, exact paper, and exact journal.

4. Pilot design

Measure ELF magnetic fields and low-frequency noise at 8–10 Hammond small businesses, pair the measurements with anonymous worker-reported fatigue and attendance data, and use Purdue research support to see whether follow-on action is warranted.

What we measure

  • ELF magnetic field baseline
  • Low-frequency noise / infrasound baseline
  • Anonymous fatigue check-ins
  • Aggregate attendance or disruption metrics, if a business agrees to share them

What we do not claim

  • No medical diagnosis
  • No causal conclusion from baseline data alone
  • No proven mitigation product
  • No individual-level health conclusions

5. Local context

Hammond + Unilever + West Lake Corridor

Those names define the local business setting for the pilot. The SBDC story is plain: protect workforce productivity while keeping the study measurement-first.

Purdue research infrastructure

Purdue research support provides the analysis path and documentation needed to decide whether a follow-on grant application is justified.

6. Roadmap

  1. Recruit 8–10 businesses and calibrate the instruments.
  2. Collect 90 days of exposure and workforce data.
  3. Summarize what was found for the SBDC and local employers.
  4. If the data justify it, pursue NIH SEED SBIR/STTR or EDA Planning and Local Technical Assistance.[7][8]

7. Ask

One SBDC support letter to Purdue research partners that says this is a legitimate Hammond workforce and economic-development pilot worth helping with.

One sentence for Frank Mrvan’s staff: “We want to protect Hammond small businesses by measuring whether the new corridor environment is associated with a local exposure baseline that affects attendance and performance, using existing Purdue research infrastructure to produce a clean, fundable dataset.”
