Huntingdon, Tennessee, in west Tennessee, has traditionally released an average of 5 ppm ammonia in their effluent.

​In 2011, leachate began to be introduced from a landfill in a neighboring town. Ammonia levels in the leachate were as high as 4,100 ppm, and the effluent of the Huntingdon wastewater lagoon climbed to 60 ppm by the middle of April, 2012.

With 11 days remaining before their effluent ammonia permit dropped to 10, Bio-Chem reached out to the operators of the land fill and stopped the leachate deliveries temporarily, and began applying its Revive biological product in the collection system.
