NWI Occupational Exposure Baseline Pilot

⚠️ The Problem

The West Lake Corridor (electrified Monon Line) opened March 31, 2026, introducing 25 kV AC overhead catenary systems to an already heavy industrial zone.

No one is measuring the combined occupational exposure to:

ELF/EMF — Extremely low-frequency electromagnetic fields from rail power and industrial equipment
Infrasound — Low-frequency acoustic pollution (1–20 Hz) from pile driving, machinery, and rail operations

This is not about proving harm. This is about establishing baseline data — the same logic as Phase I environmental site assessments, radon testing, or lead paint surveys.

🏭 The Industrial Corridor

The Hammond-Whiting-East Chicago corridor is one of the most industrialized regions in the Midwest:

Employer	Type	Est. Workers	Potential EMF/Infrasound Sources
BP Whiting Refinery	Petroleum	~3,500	High-voltage equipment, pumps, compressors
Cleveland-Cliffs Burns Harbor	Steel	~3,000	Arc furnaces, rolling mills, heavy machinery
Cleveland-Cliffs Indiana Harbor	Steel	~4,000	Electric arc furnaces, cranes, conveyors
Unilever	Consumer Goods	~300	Production lines, packaging machinery
Dover Chemical	Chemicals	~200	Reactors, pumps, ventilation systems
Cargill	Agribusiness	~150	Grain handling, conveyors, fans

New Variable: Electrified Rail

8.3 miles of new electrified corridor
25 kV AC overhead catenary — generates time-varying magnetic fields
Train frequency: ~30 trains/day during peak operations
Infrasound sources: Rail-wheel interaction, braking, passing trains

Compounded exposure: Workers in this corridor may be exposed to EMF and infrasound from multiple overlapping sources — industrial + rail + ambient.

⚡ EMF/ELF Exposure

What Are ELF/EMF?

Extremely low-frequency electromagnetic fields (3–300 Hz) are generated by:

Power transmission lines
Electric rail systems (25 kV catenary)
Industrial electrical equipment
Transformers, motors, switchgear

Health Classification

Organization	Classification	Year
WHO/IARC	ELF magnetic fields: Group 2B (possibly carcinogenic to humans)	2002
EPA	Calls for additional research on occupational exposure	2024

Peer-Reviewed Evidence

Study	Finding
Jafari et al. (2025) Int J Occup Hygiene	Systematic review of ELF-EMF occupational health impacts (2015–2023). Found associations with fatigue, sleep disturbance, and neurovegetative symptoms.
Zhang et al. (2016) PLoS ONE	Meta-analysis: OR 1.72 for childhood leukemia at exposures ≥0.4 µT.
Hosseinabadi et al. (2020) Int J Occup Hygiene	Found significant associations between occupational ELF-EMF exposure and burnout, depression in power plant workers.
Bowman et al. (2013) NIOSH	Economic analysis: $5,100/worker/µT benefit from magnetic field mitigation.

🔊 Infrasound Exposure

What Is Infrasound?

Sound waves below 20 Hz — often inaudible but can affect the vestibular system and cause physical symptoms:

1–20 Hz — Infrasound range
20–200 Hz — Low-frequency noise

Industrial Sources

Source	Frequency Range	Context
Pile driving	2–20 Hz	Construction, rail expansion projects
Heavy machinery	5–50 Hz	Compressors, generators, mills
Ventilation systems	10–100 Hz	Industrial HVAC, exhaust fans
Rail operations	5–30 Hz	Train passing, braking, wheel-rail contact
Electric motors	Variable	Large industrial motors, conveyors

Health Effects (Peer-Reviewed)

Study	Finding
MDPI Applied Sciences (2021) "Low-Frequency Noise and Its Main Effects on Human Health"	Systematic review found infrasound associated with sleep disturbance, annoyance, nausea, dizziness, and vestibular effects.
RIVM Report (2020) Dutch National Institute for Public Health	Found infrasound from wind turbines linked to sleep disturbance, headaches, and nausea in nearby residents.
Pile Buck Magazine (2024) Industry Review	Construction industry acknowledges pile driving produces significant infrasound requiring mitigation.

Why infrasound matters: Unlike audible noise, infrasound is not easily blocked by standard hearing protection. It can penetrate walls and affect workers without their awareness.

🛡️ What We Will NOT Claim

To maintain SBDC credibility and scientific integrity:

❌ We will NOT claim EMF or infrasound causes specific diseases
❌ We will NOT target any specific company or facility
❌ We will NOT seek regulatory action or enforcement
❌ We will NOT disrupt operations or create public alarm

What We WILL Claim

✅ No baseline data exists for this corridor
✅ WHO/IARC classifies ELF magnetic fields as Group 2B
✅ Peer-reviewed literature supports further study
✅ Measuring exposure ≠ asserting harm
✅ Baseline data enables future comparisons

📋 The Ask

SBDC Support Letter

We are asking the NWI SBDC for a letter of support endorsing this pilot as a fundable economic development initiative for Northwest Indiana.

The letter would:

Endorse the pilot as a legitimate occupational health baseline study
Note the regional importance of the Hammond-Whiting-East Chicago corridor
Support SBIR Phase I application for federal funding
Enable equipment access through Purdue RF Alliance

No funding requested from SBDC.

Funding Pathway

Phase	Source	Amount	Purpose
Phase I	SBIR (NIEHS/NIH)	$323,090	Baseline monitoring, equipment, analysis
Phase II	SBIR (NIEHS/NIH)	$1–2M	Longitudinal study, expanded monitoring

Timeline

May 2026: SBDC support letter
June 2026: Purdue RF Alliance equipment access
August 2026: SBIR Phase I submission
Q1 2027: Baseline data collection begins

Regional Benefit

Workers: First baseline exposure data for the corridor
Employers: Data to inform workplace safety decisions
Region: Positions NWI as leader in occupational health monitoring
Research: Creates dataset for future academic collaboration
