BMS & San Juan Cooperative identify and Bacterial problems on Lake Atitlan

Generally regardless of the town all storm / waste water is run directly into the final down stream collection point, (Sea or Lake).  This has occurred for 100's of years in Latin America increasing the bacterial levels in the river bed strata as well as the lake beds.

BMS / Dillon Oberholzer designed and prototyped a filtration and dispersion system to combat and eradicate both the Bacteria and Micotoxins / Aflatoxin whilst eliminating heavy metals from the natural main drinking water sources.
