Risk Assessment and Remediation
After a DSI indicates there is some risk to people or ecological receptors, or if ground is going to be disturbed for construction/development or activities at a site, then in many cases risk assessment may be the next option, and/or remediation.iEnvi provides experts who have done it all before. We want the “A” team involved to provide you with the best opportunity to be guides successfully. Our global collaboration model with universities and other firms means you will always get the best solutions and the best experience injected into your remediation project.A human health and ecological risk assessment (HHERA) is a quantitative calculation of contamination concentration thresholds and risks to identify human health or ecological receptors. This involves detailed analysis of the amount of time, and specific types of receptors, and detailed calculations on the decay or contaminant concentrations through soil and other pathways to a receptors.Often a HHERA will result in a reduced cost of remediation, or may avoid the need for remediation altogether.However, if remediation is required, then a process should be followed that is compliant, skilled and minimises commercial uncertainty. We aim to provide information that can be used for financial planning, approval in board meetings, and financing. To do this, we estimate time frames and potential cost ranges early in the process, based on significant experience of our relevant experts.We remediate soil, groundwater, soil vapour and water – which means we find the most technically and economically successful strategy and technology, and implementation process to benefit the requirements of each project.
A remediation action plan (RAP) should be developed first, to assess remediation strategies that may best be suitable for the site, budget, timeframe and type of contamination; and be compliant and technically successful. From each shortlisted remediation strategy, a set of remediation technologies should be assessed against criteria for the project, and initial pilot trials and/or laboratory bench scale testing may be completed to test which is the most effective technology, or the calibration of the technology, prior to full scale remediation.iEnvi employs a variety of experienced experts in risk assessment and remediation, and also partners with universities and other firms to ensure the best and most experienced team for each contamination problem is selected for remediation to be completed successfully for you.
