Management of Contaminated Land and Groundwater 

The EPA’s publication “Guidance on the Management of Contaminated Land and Groundwater at EPA Licensed Sites” and associated Reporting Templates provide assistance and information for individuals and organisations engaged in the management of contaminated land and groundwater at EPA licensed sites. 

The risk-based approach in this guidance is considered best practice for the assessment and remediation of contaminated land and groundwater at EPA licensed sites. This consistent approach ensures that the standard of works undertaken is adequate, that issues are understood and dealt with appropriately and that both operators and the EPA work towards achieve the aim of closing out the issues on contaminated sites in an efficient manner. 

The risk assessment methodology follows a staged approach, designed to ensure that key elements are addressed in succession and only as needed. The three main stages are: 

STAGE 1: Site Characterisation & Assessment 

STAGE 2: Corrective Action Feasibility & Design 

STAGE 3: Corrective Action Implementation & Aftercare. 

A critical element of the methodology that underpins the entire process is the establishment and use of a Conceptual Site Model (CSM) for the land and groundwater environment. 

This Guidance is a live document and will be updated periodically to reflect changes in legislation, technical guidance and industry best practice.
