Power Lines & ELF Exposure in Fontana, CA
How Power Lines Affect Fontana Residents
Fontana has 41 transmission lines and 25 substations within 5 miles of the city center. This includes 4 lines carrying 345 kV or more — the highest voltage class, which produces stronger ELF fields over a wider area. For homes near these corridors, distance is critical: ELF drops off sharply, but high-voltage lines have a larger impact zone than lower-voltage infrastructure.
Substations Near Fontana
With 25 substations in the area, Fontana has significant power distribution infrastructure. These are the points where high-voltage power is stepped down for local use. Each one creates a localized ELF field — if you live within a few hundred meters of one, it likely contributes to your score. The map shows exactly where they are.
Fontana's ELF exposure is rated Moderate
Some parts of the city are near high-voltage transmission corridors (345+ kV), which have a wider ELF impact zone. If you live near visible power lines, checking your address will show how much they contribute to your personal EMF score.
RF vs ELF in Fontana: Cell towers have a somewhat bigger impact than power lines in Fontana (RF: 57, ELF: 40), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Fontana has some high-voltage (345+ kV) infrastructure nearby, which creates stronger ELF fields over a wider area than lower-voltage lines. If you're close to one of these corridors, it can meaningfully impact your score — the map shows exactly where they run.
How Fontana Compares: Cell Towers & EMF Scores
