"To Whom It May Concern:

The Bridgeport Public Schools has used an electrostatic water treatment system from ElectroStatic Technologies, Inc. for more than seven years to purify water before the water enters the boilers used to generate heat for our schocl buildings. This letter is to inform all that are interested that we are extremely pleased with the service provided by ElectroStatic Technologies and by the system purchased from them.

The system we currently have has been in service for more than seven years, and has been trouble free. We have found this system to be effective and efficient. In my view the performance of this system has been especially impressive given the "hard" water in our area.

Respectfully,

Jim Calder
Superintendent."
