Expert Witness – Advising on contaminationrisks and liabilities from diesel spillClient: A UK law firm on behalf of a leading petrol retailer ESI’s specialist staff undertake numerous expert witness appointments to assist parties facing possible or actual litigation or regulatory enforcement action, or in support of waste management permitting and water resources or planning appeal hearings. Following failure of pipework a major retailer lost up This work included advising as an independent to 100,000 litres of diesel to the shallow subsurface appointed expert for the retailer on best practice in the close to a river in northern England. The migration assessment and management of risks and liabilities of hydrocarbons through the shallow groundwater arising from uncontrolled release of hydrocarbons and drains system led to river impacts, and an active and their impact on neighboring sites and surface remediation system based on soil vapour extraction watercourses, and appraisal of remedial actions. and product skimming was implemented at the site. Following completion of investigations and a detailed ESI was asked to provide expert witness services, quantitative risk assessment, the findings demonstrated advising on the migration and fate of diesel in the that active remediation has addressed all significant subsurface environment, and assessment of the contamination risks at the site. Further consultation residual risk and remedial actions required to address is now ongoing to ensure that all stakeholders can controlled waters and human health risks. provide relevant input before final report issue, remedial system decommissioning, and nearby site development for residential end use.
  • 6. 3. Understanding abstraction impactson stream ecosystemsClient: Severn Trent Water ESI has established a dedicated consortium to provide state-of the-art eco-hydrology services to water companies.
