Short Description

The EPI (Estimation Programs Interface) Suite™ is a Windows® based suite of physical/chemical property and environmental fate estimation models developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC). EPI Suite™ uses a single input to run the following estimation models: KOWWIN™, AOPWIN™, HENRYWIN™, MPBPWIN™, BIOWIN™, BioHCWIN, PCKOCWIN™, WSKOWWIN™, WATERNT™, BCFWIN™, HYDROWIN™, KOAWIN and AEROWIN™, and the fate models STPWIN™, WVOLWIN™, and LEV3EPI™. EPI Suite™ was previously called EPIWIN. EPI Suite™ is a screening level tool and should not be used if representative measured values are available.
