Verde have a team of hydrogeologists who are experienced in analysing, controlling and protecting groundwater.
Hydrogeological assessments would typically be required for facilities in two instances:
This is followed by a determination of the appropriate tier of hydrogeological assessment required:
Preliminary Site Assessment (low risk sites)
A Tier 1 assessment comprises an assessment of past monitoring data, past hydrogeological assessments and publicly available data (e.g. EPA, GSI databases).
Detailed Quantitative Risk Assessment (moderate risk sites)
A Tier 2 assessment involves the above, in addition to further monitoring and a comparison of monitoring results with Generic Assessment Criteria (e.g. Groundwater limits stipulated as per the Groundwater Regulations, 2010).
Detailed Quantitative Risk Assessment (high risk sites)
A Tier 3 Assessment involves the above, in addition to a comparison of monitoring results with site specific criteria, calculated in accordance with EPA Guidance on the subject (e.g. using the UK CLEA Model). Typically a Tier 3 assessment would require an in-situ intrusive investigation and a 3rd party contractor would typically be procured to carry out such works.
Upon completion of the hydrogeological assessment we can determine whether a client complies with the Groundwater Regulations of 2010 / the Water Framework Directive ‘Prevent or limit’ Objective. A hydrogeological assessment report will be the final product provided to the client.
