This page takes each specific health concern seriously and addresses it honestly. Some are legitimate, with documented evidence and real regulatory responses. Others are overblown and circulate widely online despite little supporting evidence. Homeowners who cite the overblown ones at hearings hurt their case — they get lumped in with conspiracy theorists and commissioners tune out. Homeowners who cite the legitimate ones, with specifics, can meaningfully shape site plan conditions.

1. Electromagnetic fields (EMF) and "radiation"

What's claimed: Some online content claims data centers emit dangerous levels of electromagnetic radiation or microwaves, associated with cancer risk.

What's documented: Data centers themselves do not emit significant electromagnetic radiation like a cell tower or radar installation does. Servers operate at frequencies and power levels comparable to ordinary office computer equipment, just in greater quantity. The high-voltage electrical infrastructure (substations, transformers, transmission lines) generates low-frequency 60 Hz electromagnetic fields similar to any electrical substation. Epidemiological research on residential proximity to substations is mixed and does not establish a clear causal link to health outcomes.

What to put on the record: This concern generally does not hold up at a hearing unless you live very close to a proposed substation specifically. Citing "radiation" or EMF in public comments undermines stronger claims. Focus on other concerns below.

2. Diesel generator emissions

What's documented and real: Hyperscale data centers have extensive diesel backup generators. A 500-MW facility might have 100+ large diesel generators totaling 100+ MW of backup capacity. These must be tested regularly — monthly or more often — running at load for 15-30 minutes per test. Modern diesels are cleaner than older ones but do emit particulate matter, nitrogen oxides, and combustion pollutants during operation and testing.

Air permitting review through the Florida Department of Environmental Protection is a real regulatory checkpoint. Cumulative emissions during extended grid failure (like after a hurricane) can be significant.

What to put on the record:

  • Request disclosure of total diesel generator capacity, testing frequency, and testing hours
  • Ask about pollution control equipment (Tier 4 compliant or older)
  • Request conditions limiting testing to specified weekday daytime hours
  • Ask what the air permit requires in terms of emissions monitoring
  • If you or family have asthma, COPD, or respiratory conditions, document this

3. Water quality concerns

What's documented and real: Newton County, Georgia residents near a Meta facility have documented sediment contamination, well failure, and significant financial harm. Evidence suggests construction practices, not the operational facility, drive most documented well water problems. Runoff management, sediment control, and erosion practices during the 12-24 month construction phase are the critical period.

What to put on the record:

  • Request specific construction stormwater management plans
  • Ask for pre-construction well water testing for residents within 1 mile
  • Ask what remediation the developer will provide if nearby wells show contamination
  • Request post-construction water quality monitoring for at least 3 years

See our dedicated well water page for more.

4. Noise-related stress and sleep disruption

What's documented and real: Chronic noise exposure is associated with sleep disruption, increased stress hormone levels, and cardiovascular effects in epidemiological studies. Continuous low-frequency cooling hum plus periodic diesel generator tests — residents in Mansfield, Georgia report exactly this from a Meta facility. This is a real issue, not imagined.

Noise is one of the most tractable issues at the site plan stage. Setbacks, sound walls, mature landscaping, and enforceable decibel limits actually work.

What to put on the record:

  • Request strict enforceable decibel limits at your property line during nighttime hours
  • Request independent acoustic study before operations and after one year
  • Ask specifically what the enforcement mechanism is if limits are exceeded
  • If family member has sleep disorders, autism, PTSD, or noise-sensitive conditions, document this

See our dedicated noise page.

5. Air quality from construction activity

What's documented and real: Construction of a hyperscale facility involves significant land clearing, heavy equipment, and truck traffic over 12-24 months. This raises local particulate matter during construction. Environmental reporting near the Meta Newton County site documented visible dust migration onto neighboring properties.

What to put on the record:

  • Request construction dust control plans
  • Ask about truck routing to minimize residential road impact
  • Request construction hour limits (typically 7 AM to 6 PM weekdays)
  • Ask what the remedy is if dust migration affects neighboring properties

6. "Cancer clusters" and chronic disease claims

What's claimed: Some online content asserts residential proximity to data centers increases cancer rates.

What's documented: No peer-reviewed epidemiological study has established a link between residential proximity to data centers and elevated cancer rates. This does not mean no risk exists — it means no such link has been scientifically documented. Citing unsupported claims in a public hearing undermines your credibility on the better-documented concerns.

What to put on the record: Focus on documented concerns above rather than speculative disease claims. Specific, documented concerns carry far more weight than general health-harm assertions.

7. Fire risk

What's documented: Data centers have had fires, though rare. Risks concentrated in battery backup systems (lithium-ion fires are difficult to extinguish) and diesel fuel storage tanks. Local fire departments must be consulted on the site plan. The developer's fire suppression design should be part of the public application.

What to put on the record:

  • Ask about fire suppression design for battery rooms and fuel storage
  • Ask whether local fire department has capacity to respond to a major data center fire
  • Request the emergency response plan as a public record

The summary, honestly

Strongest evidence for concern is in diesel emissions, construction dust, noise-related sleep disruption, and construction-phase water quality impacts. Those are documented, quantifiable, and addressable through site plan conditions. Cancer cluster claims, EMF hazards, and similar speculative concerns are not well-supported and weaken credibility. Florida commissioners, like most public officials, take specific and documented concerns seriously. They dismiss speculation. Lead with the documented ones.
