Subsurface work around JFK can yield very high volumes of water due to the sandy subsurface conditions. 18 wells were installed along with a 2,000 Gallon Per Minute dewatering system to create a safe and dry working environment for the sewer relocation. There also happened to be high levels of Volatile Organic Compounds in the area which required treatment. Utilizing a bag filter and carbon absorption system, the water was treated for discharge to local waterways.
