# NWI EMF Pilot — Literature Chain

## What is established

ELF electric and magnetic fields are **non-ionizing** exposures. Typical sources include power lines, household wiring, appliances, motors, and industrial electrical systems. In this project, EMF refers to non-ionizing fields spanning both ELF and RF sources: power lines, wiring, motors, industrial electrical systems, Wi-Fi, and Bluetooth. UV and X-rays are different, ionizing categories. WHO defines non-ionizing radiation as the part of the electromagnetic spectrum where there is insufficient energy to cause ionization, and IARC classifies extremely low-frequency magnetic fields as **Group 2B: possibly carcinogenic to humans**. [^1][^2]

IARC’s classification reflects a limited but persistent epidemiologic signal, especially for childhood leukemia. That is a **cancer-risk** signal, not proof of harm at any specific site, and it should not be stretched into claims about every symptom people report. [^2]

## What is mixed or inconclusive

For low-frequency noise and infrasound, the literature is mixed. A systematic review in *Science of the Total Environment* found associations with annoyance, sleep-related problems, concentration difficulties, and headache in some exposed populations, but the studies were heterogeneous and not causal proof. [^3]

Controlled experiments have sometimes been null. For example, a double-blind randomized crossover study in *Environmental Health Perspectives* found no detectable adverse effects from 72 hours of simulated wind-turbine infrasound in noise-sensitive, healthy adults compared with sham exposure. [^4]

So the defensible statement is: **there is enough signal to justify measurement, but not enough evidence to claim causation for symptoms.**

## Why Hammond now

The South Shore Line says Monon Corridor service on the West Lake Corridor opened on March 31, 2026, changing the local rail environment in Hammond and neighboring communities. [^5]

Unilever also operates the Hammond Dove Bar Soap Factory. That makes the area a reasonable place to test whether a local exposure baseline is worth tracking for workforce and operations planning. [^6]

## What the pilot tests

This pilot will test a narrow question:

> Do measured ELF magnetic fields and low-frequency noise at Hammond small businesses near the new corridor line up with anonymous worker-reported fatigue, absenteeism, or task disruption?

That is a **baseline and correlation** question first. If a low-frequency acoustic component appears material, phase-inverted mitigation is only an exploratory HYPOTHESIS to test; it is not being presented as a proven treatment or product.

## Funding and implementation path

NIH SEED’s SBIR/STTR program is a non-dilutive path for small-business health R&D. EDA Planning and Local Technical Assistance is an additional public funding route for regional measurement and economic development work. [^7][^8]

That is the practical chain: **measure first, keep claims narrow, and only then decide whether there is a case for intervention or grant-scale expansion.**
