On-Demand Webinar Recording
This presentation will benefit practitioners and regulators who want an understanding of how different techniques can work together to develop a robust CSM or who wish to understand the practical endpoints to remediation.
We will discuss a site that was initially assessed using standard techniques of groundwater, soil and soil vapour analysis. Whilst this enabled a general understanding of the LNAPL CSM, further details and a higher resolution of data was required to obtain a detailed knowledge of contaminant distribution (laterally & vertically) to understand the risks posed by the site, target remediation activities and plan for long term sustainable management. This data was obtained using a Laser Induced Fluorescence (LIF) assessment. The refined LNAPL CSM allowed the existing remediation system to be repurposed to focus on the most impacted areas of the site and also to plan a Natural Source Zone Depletion (NZSD) assessment. The targeted NSZD assessment was used as part of a lines of evidence approach to show that further remediation was not required.

Danny,
Principal Environmental Geoscientist
Danny is a Principal Environmental Geoscientist and Certified Environmental Practitioner, Site Contamination Specialist (CEnvP SC), with 15 years’ experience in the field of environmental science.
Danny has held a number of roles including client manager for a major petroleum company, a role which saw him oversee approximately 60 projects involving assessment, risk assessment/management, remediation and stakeholder relations. He has a special interest in incorporating sustainable management practices and/or remediation into his projects. This includes a project where soil washing was utilised to remove oil from 40,000m3 of sand rather than offsite disposal, and the current project, where a sustainability assessment lead to the completion of active remediation.
