Hazards of Extremely High Voltage (EHV) Transmission Lines

  • Herbicide Drift

  • Contamination of Aquifers

  • Child Leukemia

  • Alzheimer's

  • Pacemakers and Defibrillators

  • Anxiety & Depression

  • Noise Pollution

  • Bird Deaths

  • Bee deaths and abandoning of Hives

  • Stray Voltage

  • Other Animal and Plant risks

Fire Hazards of Transmission Lines Start on Day One!

What does SWEPCO plans to do with 800 acres of trees and debris?


Utility crews usually burn trees and debris on-site, to save cost, creating fire hazards.


This is a serious concern for our Volunteer Fire Departments. Do we want to risk their lives?


The 2011 Bastrop, TX fire, caused by a transmission line killed 2 people , caused $325 Million in destruction, decimated over thirty thousand acres of land and destroyed over 1,500 homes. It lasted from 9/4/11 to 10/10/11, 31 Days.




Hazards of Herbicides and Herbicide Drift


Drift is when herbicides move off the location where they were applied and can  occur both during application (partial drift spray) or after application (vapor drift).


Drift can be as long as 1-4 miles!


2,4-D and dicambia, two very common herbicides are both notoriously prone to drift, causing injury and plant death to nearby crops and rural landscapes.


2,4 D can contain TCDD which is classified as "carcinogenic to humans" by the International Agency for Research on Cancer


A study confirms the GMO herbicide glyphosate contaminates groundwater. Glyphosate can cause kidney and reproductive problems.


Atrazine a possible human carcinogen can degrade in soil to metabolites, which can enter groundwater.


Health Risks for people associated with Transmission Lines

The risk of Childhood Leukemia doubles within 320 feet of transmission lines


  • Children under the age of 15 living within 320 feet of high-voltage transmission lines have close to twice the risk of developing leukemia.


  • Children aged 0-5 are the most vulnerable and their risk is even higher. Oxford Childhood Cancer Research Group, 2004


Alzheimers and Senile Dementia


The risk for people living within 160 feet of EHV transmission lines compared to people living 2,000 feet or more away increases by:








Hazards to Pacemakers from Strong Electromagnetic Interference (EMI)


Biotronik & The Buffalo Heart Group warns patients to Avoid High Voltage Transmission Lines.


  • Inhibition of pacing for a slower than normal heart rate, patient could lose consciousness.


  • Noise mode pacing, the device will pace irregularly rather then timed with the patients heart.


  • Back-up mode, device will not operate under the physicians parameters, physician will have to reprogram device.



Anxiety Disorders & Depression


  • Medical evidence has demonstrated that EMI, EMF & ELF cause adverse effects of melatonin secretion which result in abnormal: Cognition, Nervous system function, and Brain activity


  • The risk of severe depression was increased by 4.7% among subjects living within 330 feet of a high-voltage transmission line.



Constant Transmission Line Noise cause anxiety, headaches and depression.


  • Corona noise is most common, it is heard as a crackling or hissing sound, caused by the electrical field at the surface of conductors. The Corona noise increases in high humidity and during rain and fog.


  • Insulator noise is caused by dirty, nicked, or cracked insulators.


  • Aeolian noise is caused by wind blowing through the conductors and tower structures.






Stray Voltage ... ZZZZAAAAP!!!!!

Stray Voltage has not been brought up before, but it is a real concern for people and wildlife. EHV Transmission lines can give you electric shocks when current flows from the conductors to the ground if you are close to the line; the people that work on EHV lines wear a long chain around their waist dragging it as they walk to have the current flow through the chain to the ground and not their body.    



Hazards to animals and plants due to Transmission Lines

Bird Deaths : In the U.S. transmission lines kill from 10 to 175 million birds every year from bird strikes and tens of thousands from electrocution


Migratory Bird Deaths: For large, slow reproducing migratory bird species, such as Bald Eagles, birds of prey, cranes, geese, vultures and owls, the death toll from transmission lines could lead to local and regional extinction.


Hazards to Bees: EMF can cause bees to become aggressive, stinging each other to death, and the bees leave hives forever. ELF cause colonies to leave and never come back.


Additional Hazards for Animals and Plants due to Electrostatic Fields. Animals and livestock kept in metal pens near transmission lines can get shocked when they eat or drink. E. S. Fields prevent full growth of plants and grains.
