Can you elaborate? A substation is about to start construction just across the (narrow) street from my child's elementary school.

I used to work in the contact centre for my country's radio spectrum regulators, we'd get numerous phone calls from people who were terrified of or complaining about the "radiation" part of "electromagnetic radiation" from power equipment or celltowers or radio transmitters.

I'd say 1/3 were reassured by my explanation of why non-ionising radiation isn't going to harm your unborn child/give you cancer[1], 1/3 decided I was a lying tool of the Establishment and They Knew The Truth, and the last 1/3 had a genuine mental illness - "No you don't understand, the Prime Minister has authorised the Police to monitor my TV viewing using radio waves and it's giving my family cancer".

[1]Unless you're climbing a transmitter tower and exposing your womb to a focused microwave beam at a very close range for a substantial period, then the heating effect probably isn't going to be doing good things.

That's exactly what I'd expect from a lying tool of the Establishment.

If I were in your position, I would ask (privately, to avoid unnecessarily freaking everyone out) what their limits on stray voltage and stray current are outside the substation and what they do to control and monitor it. 60 Hz radiation doesn’t seem like a credible risk at all to me. 60 Hz conducted emissions, on the other hand, can very easily kill you — imagine crawling in hands and knees two feet from a downed powerline.

I would like to imagine that regulators and utilities have this under control, but making some effort to verify this could be reasonable.

(49 states permit utilities utilities to ground a current carrying overhead wire at utility poles, resulting in parallel currents in the ground. I’m not aware of this being a documented hazard to people, but it’s a documented problem for cattle. CA is the exception.)

the em waves produced by substations induce fear of decreasing home values via an unknown mechanism.
If you get the chance, watch "Better Call Saul" sometime. Jimmy's brother Chuck feels he is sensitive to electromagnetism and goes to extreme lengths to protect himself from the waves.

Abstract This 2019 brochure is intended to explain the issues surrounding EMF. It covers the physical nature of EMF, our everyday exposures to EMF, the health research and its findings, and the conclusions reached by expert scientific panels and government agencies. It provides key updates to the review of the science that the National Institute of Environmental Health Sciences (NIEHS) published in 2002 in a booklet entitled, “EMF: Electric and Magnetic Fields Associated with the Use of Electric Power – Questions & Answers.” The 2002 booklet contains very useful information that remains current, and that the reader of this brochure may find of value.
