Power Lines & ELF Exposure in Rialto, CA
How Power Lines Affect Rialto Residents
Rialto has 55 transmission lines and 31 substations within 5 miles of the city center. This includes 1 line 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 Rialto
With 31 substations in the area, Rialto 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.
Rialto'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 Rialto: Cell towers have a somewhat bigger impact than power lines in Rialto (RF: 62, ELF: 44), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
