Hydrogeological Assessments | Verde - Complete Environmental Solutions Hydrogeology – Verde – Complete Environmental Solutions

Hydrogeology

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:

1

Facilities that have had technical amendments to their licence (IPC/IED/Waste) requiring that they assess their impacts on groundwater and compliance with the Groundwater Regulations, 2010. Such licensees must demonstrate compliance with the regulations before the 22nd of December 2015.

2

Facilities that have discharges to ground. The first step is to describe the receiving environment and develop a Conceptual Site Model detailing pollution sources, pollution pathways and sensitive receptors.

This is then followed by a determination of the appropriate tier of hydrogeological assessment required:

Tier 1

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).

Tier 2

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).

Tier 3

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.
