Hydraulic Fracturing Fluids Discharged

Liquid nitrogen tanker trucks transport gas to the site for nitrogen foam fracturing. Nitrogen will travel through pipes to be mixed with water and a foaming agent at the wellhead prior to injection. The foam is used to create and propagate the fracture deep within the targeted coal seam.







The fracturing fluids, additives, and proppant are pumped to the wellhead and mixed just prior to injection. (Secret Sauce of non-disclosed toxic chemicals)




Fluid that is extracted from the well is sprayed through a diffuser and stored in a lined trench until it is disposed of off-site or discharged.










Discharged?  Is that what the EPA stated in their documents?
Discharged where?
