The need to contain and filter acid runoff from 700,000 cubic yards of pyretic rocks that were unearthed during the I-99 construction. Many environmental concerns for the local water sources were raised [photo 1].
Geotube® dewatering technology was used to contain and dewater contaminated sediments. The acid runoff collected into sediment ponds; then it was pumped into a sedimentation tank. Polymer was mixed into the solution tank, and then mixed into the contaminated slurry before entering the Geotube® unit [photo 3].
The resulting effluent released from the Geotube® unit [photo 5] was very clear.
Local streams and groundwater were relieved of iron oxide contaminants. This eliminated the environmental problem caused during the interstate construction.
