CRC for Contamination Assessment and Remediation of the Environment (CARE), Adelaide, Australia: CRC CARE Technical Report No. 47, 263 pp, Mar 2020

The project "Towards national guidance of natural source zone depletion (NSZD)" was initiated by CRC CARE to understand the role of NSZD in the management of LNAPL contaminated sites. This report complements the LNAPL NSZD application guidance document The role of natural source zone depletion in the management of light non-aqueous phase liquid (LNAPL) contaminated sites and the LNAPL NSZD measurement guidance document Technical measurement guidance for LNAPL natural source zone depletion (both available at https://www.crccare.com/publications/technical-reports). This document provides detailed, Australian-specific measurements and case studies for six sites and multiple LNAPL product types. For these sites, NSZD rates were estimated for a range of LNAPLs, such as crude oil, diesel, jet fuel, and gas condensate. The NSZD rates are compared to the most representative active product recovery rates from each of these sites to provide context to the scale of the NSZD rates. https://www.crccare.com/files/dmfile/CRCCARETechnicalReport47_AustcasestudiesofLNAPLNSZDrates.pdf
