Delaware Creosote Remediation
A sequenced treatment approach using SEPR followed by S-ISCO successfully remediated creosote DNAPL contamination at a US EPA Superfund site in Delaware. The initial treatment was designed as a pilot test but, based on the very high volumes of product recovered within the first two weeks of the project, the treatment area was immediately expanded and the implementation progressed directly into full scale. Therefore the project was considered a full scale operation comprising of two phases of injections – Phase I and Phase II. During Phase I of the project, the sequenced SEPR and S-ISCO remediation, successfully removed more than 88% of the creosote-related DNAPL identified in the treatment area; and Phase II, conducted in an expansion of the Phase I area and at lower depths yielded 72% DNAPL removal.

Louisiana Creosote Remediation
VeruTEK conducted a successful pilot test implementation at a creosote site in Louisiana following completion of a bench scale treatability study. The pilot scale was used as an evaluation of the SEPR technology and demonstrated the process’ cost effectiveness for full scale implementation. SEPR improved DNAPL removal from the existing recovery system by up to 17 times baseline conditions, generating approximately 1700 gallons of total recovery. DOWNLOAD CASE STUDY >>
