Persistent Contamination

Some groundwater contamination remains difficult to remove, residing as DNAPLs or in difficult-to-treat areas such as fractured geologic media and low permeable zones.  SERDP and ESTCP efforts seek to better understand what causes persistent contamination and which methods are most effective in remediating and monitoring such sites.
