Effective Microorganism uses naturally-occurring microorganisms such as lactic acid bacteria, photosynthetic bacteria, yeast, fermenting fungi, and actinomycetes that are claimed to purify and revive nature. Applications of EM using the formula known as Effective Microorganism Activated Solution have been experimented on water from three wells in DMMMSU Agoo, Campus. This study aimed to determine the quality of water from the wells before and after EM application. The EM's effectiveness in reducing bacteria was noted three weeks after the application while EM's capability to decrease yeast was noted for two weeks after the application. Moreover, pH was improved within the standard range except in one well three weeks after EM application.
