15.30 Case Study: Effective Site Characterisation to Support Risk Assessment and Provide Proportionate Remediation Scope
This presentation will provide details of an ongoing remediation scheme at a former MOD site currently being redeveloped by the Department of Education as a multiple use educational campus. The site is being redeveloped to provide shared educational and sporting facilities for up to 4,000 students and represents Northern Ireland’s most significant educational infrastructure investment in recent years.
The presentation will include details of the following:
- Site investigation design and development of the Conceptual Site Model
- Design of the overarching remedial programme for inclusion within the Works Information for the procurement of the earthworks contract.
- Detailed technical review of the previously proposed remedial strategy, specifically with respect to a soil and groundwater hydrocarbon plume associated with a former Petrol, Oil, Lubricant (POL) Storage area.
- Supplementary site investigation design, including the collection of geological and hydrogeological data specific data relevant to the source area and along anticipated contaminant migratory pathways.
- Review of sampling techniques to achieve representative dissolved phase sample due to the potential presence of free phase.
- Low flow sampling to assess field chemistry and capacity to support contaminant degradation via natural attenuation, and use of Biotraps to assess microbial populations potentially applicable to the degradation of identified contaminants of concern.
- Detailed Hydrogeological Quantitative Risk Assessment to include parameters derived following site characterisation works.
- Refinement of Conceptual Site Model following DQRA and demonstration that contaminant concentrations in soil and groundwater did not present a potential risk to receptors and that site conditions were suitable to support the degradation of contaminants via natural attenuation; and
- Early stakeholder engagement and subsequent regulatory approval of a reduction in scope of remedial measures to comprise a programme of groundwater monitoring only (monitored natural attenuation) during construction, providing significant cost savings to the client.

15.55 Case Study: Passive drainage of deep clean groundwater as a sustainable means of reducing the spread of contaminationOn an industrial brownfield site in Northern Ireland, DuPont installed a > 500 metre long horizontal well to drain deep groundwater upgradient of a contaminated area. This allows the clean groundwater to discharge with little or no treatment and to passively contain a contamination plume otherwise reaching a receptor. The particular hydraulic conditions on site allow the groundwater to well up freely with no pumping, which makes this a lasting sustainable solution.

Nicoletta Cavaleri, Geotechnical Engineer, CH2M HILL
16.20 Case Study: A Site investigation toolbox - Practically applying a variety of techniques from low tech to high tech
There are a variety of techniques to investigate contaminated land sites. However, more often than not a standard approach of drilling and monitoring well installation is adopted. The objective of this presentation is to explore other techniques (both high tech and low tech) that can be used in conjunction with this standard approach to greatly enhance the site characterisation process.
A case study of a former industrial site in Northern Ireland will be presented. The site investigation works were designed in a staged manner, with the results of each stage informing the scope of the next. This staged approach combined with the use of some lesser frequently used techniques allowed for better targeting of areas of potential concern and ultimately a more robust site characterisation and risk assessment.
The following low tech / high tech techniques will be explored:
- Electromagnetic survey
- Cone penetration test (CPT) including Membrane Interface Probe (MIP) coupled with a Hydraulic Profiling Tool (HPT)
- Photoionization Detector (PID) and pH survey of river bank sediments
- Installation of multi-level level monitoring wells
- Installation of passive flux meters (PFM) in groundwater monitoring wells
