“Class I wells in the non-hazardous industrial or hazardous waste categories are well suited for the management of PFAS-containing waste material. Class I underground injection wells are designed to dispose of and isolate liquid wastes below the land surface and beneath USDWs. The standards associated with the construction, operation, and monitoring of Class I wells are designed to ensure protection of USDWs.” (Document # EPA-HQ-OLEM-2020-0527)
UIC technology assures isolation from drinking water aquifers by assuring that injectate is introduced into the injection zone and no place else. By maintaining and continuously monitoring a higher pressure in the annular space between the injection tubing and the long string casing, wastewater can only be placed in the permitted injection zone.
Underground injection is the proven, protective, and reliable disposal technology:
Wastewater treatment keeps the waste in our environment...
ensuring that one way or another, we will see their impact in the future. Wastewater treatment and most all other disposal methods simply rearrange waste in the environment. No matter how they're managed, the substances remain somewhere - in our surface waters, landfills, air, groundwater, and food supply. Whether they arise immediately or later on, the environmental impacts are unavoidable.
UIC disposal permanently removes the contaminants from our biosphere...
Uniquely, injection of wastewaters into a porous geological formation separated from groundwater by thousands of feet of impermeable rock assures true, permanent disposal.
At Buckeye Fluid Solutions' site, more than a MILE of rock separates the injection zone from the lower most groundwater.
