Dear Greg:

Well, we are back from the mountains of Guatemala and did we have a trip. The school building that we built was a challenge and we assembled it in four days to the delight of the Mayan village of San Migel but what pleased them the most was the "Water Filtration System". I cannot put into words the emotion that was poured out by the villagers when they saw putrid water that resembled pea soup get filtered and evolve into crystal clear water. Everyone in the village brought their containers and drank. The battery operated system worked flawlessly all of the time that we were there so there was no doubt that the solar panel functioned properly also! I have enclosed some pictures of the system for your review.

Once again, I would like to extend our heartfelt thanks to you and your wonderful staff for their help on this project. You have helped to improve the health of the Mayan people through your efforts and your great product.

Gratefully Yours,

Richard J. Enders
