Onsite Comments
The kill was a result of a leak from an anhydrous ammonia tank pipe. The cloud was sprayed down with water by the fire department. The contaminated water then entered Mill Branch Creek. . A road culvert and a tile intake/line allowed the ammonia to reach Mill Branch Creek. Mill Branch Creek flows into Cotton Creek, which then flows into White Breast Creek. Dead fish were observed in all three of these streams below the tile line.
