Alpha Analytical has revised the fractionation level for extractable petroleum hydrocarbons (EPH) from 1,700 mg/kg to 2,300 mg/kg consistent with the revised NJDEP Evaluation of Extractable Petroleum Hydrocarbons (EPH) in Soil Technical Guidance (Version 1.0) released on 06/20/19, effective on 12/20/19. The revised Guidance provides for determination of alternative product limit concentrations.
Alpha Analytical offers analytical services to support the revised Guidance. For more information, refer to Alpha’s NJ-EPH Technical Bulletin.
