I believe that this web page and its contents will be of interest to you and merit the time from your busy schedule to read.
Most people are not aware that electrical pollution – otherwise referred to as ‘dirty electricity’ or ‘radio wave sickness’ – exists, let alone are they are aware of how if affects the body.
Generated primarily by electronic devices (computers, televisions, energy efficient lighting), electrical pollution flows through our homes and above a certain level, is internalized by the body.
The damaging effects manifest themselves in a variety of ways, including chronic fatigue, depression, headaches, body aches and pains, ringing in the ears, dizziness, impaired sleep, memory loss and confusion. Children seem to be especially susceptible to this form of energy.
The benefits to a school are two-fold. When the filters are placed in schools, the teachers and students are healthier, and there is considerable cost savings to the schools, in the form of fewer sick days, disciplinary action with students and reduced computer repairs. In a Toronto school, the temperature of the computer room dropped 20 degrees (F) with the filters installed on the computer power bars.
At Melrose-Mindoro Elementary School in Wisconsin, there were 37 children using asthma puffers daily. After 2 weeks with the filters installed, there were 3 children using their puffers for gym time only.
Angela Holstad was diagnosed with Multiple Sclerosis and was off work constantly for a condition which went away on weekends. With the filters installed in her school she is rarely off sick. The same can be said of her co-workers. Disciplinary action at the school was greatly curbed, from 10 incidents a week to 10 a month.
We have installed the filters within our home, and while the results are subtle, they are significant (improved memory and focus, calmer, there is a stressor missing from the environment).
I have been advocating for the removal of dirty electricity in schools for 2 years. Please read the report which I co-authored entitled Electrical Pollution and Our Schools (PDF). This report not only outlines the issue of dirty electricity, but also clearly states the benefits.
Why does your school need to clean its electricity?
Benefits of a clean electrical environment to teachers and students
Cost Savings to Schools and School Boards
- Overall teacher wellbeing improved while the filters were in place in a Toronto school study. Teachers were less frustrated, less tired, less irritable. They were better able to focus and had better health, improved mood, and greater sense of accomplishment.
- The study results show:
- 45% of the teachers reported feeling less tired and less frustrated;
- 35% felt healthier; 30% were less irritable;
- 25% had improved mood, more energy and a greater sense of satisfaction with their work while the filters were installed.
- Staff with allergies took less medication, students with migraines experienced less pain.
- 39% to 56% of teachers may have some degree of electrosensitivity
- Sixty percent of the classes showed significant improvements in student behaviour.
- As much as 5 to 10 minutes were saved each period in unproductive activity while the Graham-Stetzer filters were installed.
- Improved power quality is associated with behaviour that is more conducive to learning in the classroom.
- Teacher absences for health-related reasons were dramatically reduced after the filters were installed in a school in Wisconsin. Fewer teacher sick days leads to less teacher substitution.
- Sick building syndrome may be due to dirty electricity rather than mold. Check electrical quality before starting a costly mold clean-up program that may not be necessary.
- Fewer computer repairs.
- Increased efficiency of operations – less time spent in disciplinary action, improved use of class time.
- A happier, calmer school.
Dirty electricity is an invisible and easily ignorable issue.
It places an unseen stressor on the body. Without the stressor, the body can function as it should.
I feel that we are being unfair to our children by expecting them to learn and behave in an environment which is not conducive to learning.
I am very thrilled that so many teachers will be aware of this new issue facing the students and their own health.

Presented at the 3 rd International Workshop on the Biological Effects of Electromagnetic Fields, 4-8 October, 2004, Kos, Greece.
A paper is a single blind study that addresses the correlation between improved power quality at Willow Wood School and improved student performance. This not only raises questions about the impact of improved power quality but also suggests electrical sensitivity affects more people than commonly assumed, which is of particular concern as the modern classroom becomes increasingly dependent on electric/electronic equipment.

A preliminary study into the effectiveness of Graham-Stetzer Filters and how they can reduce the levels of dirty power in schools, homes and offices. More importantly, the results of the study indicate a clear relationship between the blood sugar levels among diabetics, MS symptoms, headaches, and fatigue and higher levels of dirty power.

A multifaceted paper that explores the nature of electrical hypersensitivity, dirty electricity and how Graham-Stetzer filters can improve power quality by reducing the amplitude of harmonics and transients on electrical wiring. The paper also delves into how an improvement in power quality can have a direct impact on reducing the symptoms in diseases associated with electrical hypersensitivity, including multiple sclerosis and diabetes.

In light of the current proliferation of electronic equipment, the general assumption that our electrical environment is carefully studied and monitored — and is actually safe — is a large misconception among the general public. This paper addresses the source of these problems and, in particular, investigates the nature of one of the most potent contaminants due to this dangerous electrical environment: radio frequency radiation (“dirty electricity”).

This summary of the efforts on schools throughout North America in their battle with EMFs.
"Schools may become the next battleground in the EMF (electromagnetic fields) conflict. As parents learn more about EMF health effects, they are demanding measurements and, when necessary, reductions of EMF levels in classrooms and schoolyards." As Microwave News reported in April 1990, "Conflicts over EMFs in schools are not new".

by Ken Luchterhand of The Chronicle, Melrose, Wisconsin
Angela Olstad almost quit being a fourth grade teacher and principal. Although she loved her job at the Mindoro school, she couldn't handle being sick so often. She was about to quit when a cause had been found for her illness - electrical pollution.

Letter from Char Sbraggia R.N., District Nurse.
In the years previous to the filters being installed, several children required inhalation treatments for their asthma in the spring and in the fall. Many of them required nebulizer treatments once or twice a day while at school. I have not had to administer one nebulizer treatment this past year and of the 37 students with inhalers, only three of them use the inhaler for their exercise-induced asthma before Phy Ed.

Electricity, among the most marvelous discoveries and widely used inventions of modern technology, is a blessing to mankind when carefully managed, and when its effects on biological systems are understood and respected. But, like alcohol, drugs, tobacco, dioxin and certain chlorinated hydrocarbons, when electricity is not properly controlled, or its beneficiaries are over-exposed, electricity destroys certain functions of the brain and the immune system and increases proliferation of cancer. Electrical pollution of the environment is out of sight and out of mind.

Two north East Valley school districts will tackle hotbutton issues Tuesday night, as the Scottsdale board will vote on a new janitorial contract and the Cave Creek district will discuss what to do about high-voltage power lines that cross a middle school parking lot.
An investigation by ABC affiliate KSTP-TV in St. Paul, Minn., concluded that more than a quarter of West Elementary School's staff -- 28 of 102 staff members employed at least five years -- had been diagnosed with cancer.
