Furthermore the disposal of hazardous solid waste such as dead animals and veterinary was buried without cover, directly into creek and open air burning was among the unacceptable waste management disposal systems. Moreover, 75% of backyard piggery farms have high ammonia level and 25% low ammonia level was detected inside the pigerry barn using laundered t-shirt as a filter agent.
