Environmental Permits for landfill sites include a condition requiring operators to undertake a review of the hydrogeological risk assessment (HRA) that was submitted with the original application. A report, detailing the outcome of the review, must be submitted to the Environment Agency between 9 and 6 months before every 4th anniversary of the date of permit issue.

If you need assistance in undertaking the required HRA review, and submitting a report to satisfy regulatory requirements, ESI has the skills and experience to help.

ESI is an environmental consultancy with a very strong background in soil and groundwater science, and as such has wide and varied experience in undertaking HRAs and HRA reviews for waste disposal sites, including hazardous, non-hazardous and inert landfills.

We have a range of tools we can use as appropriate, and significant experience which allows us to quickly and accurately assess the level of work required under an HRA review, thus enabling operators to fulfil regulatory requirements whilst keeping cost low.

The complexity of an HRA review will depend upon the nature of the site (inert, non-hazardous or hazardous) and the specific site setting (e.g. sub-water table, proximity to sensitive receptors).
