San Bernardino has 30 transmission lines and 20 substations within 5 miles of the city center. ELF exposure drops off sharply with distance. Homes more than 500 meters from a transmission line or substation typically have very low ELF levels, while homes within a few hundred feet may experience noticeably higher exposure.
Substations Near San Bernardino
With 20 substations in the area, San Bernardino 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.
San Bernardino's ELF exposure is rated Moderate
Some parts of the city are close to power grid infrastructure. If you live near visible power lines or a substation, checking your address will show how much they contribute to your personal EMF score.
RF vs ELF in San Bernardino: Cell towers have a somewhat bigger impact than power lines in San Bernardino (RF: 53, ELF: 34), though both contribute meaningfully. Checking your address shows which sources are most relevant to your specific location.
What This Means for You
Unlike cell tower RF, which is spread across many towers, ELF exposure is very location-specific. You could live a few blocks from a power line and barely notice it in your score, or live right next to one and see a significant impact. Check your address to see if any are close enough to affect your home.
