Remediation works of hydrocarbon contamination at Waterford

Remediation works by E-Clay stabilisation of hydrocarbon contaminated soils and groundwater at Anne Street Waterford.

 

Site Overview

The site was being developed as a three storey apartment block.
Historical of the site resulted in widespread soil hydrocarbon contamination across the site. Elevated levels of Total Petroleum Hydrocarbons (TPH) were identified within the made ground and perched groundwater.
As construction had already commenced the main contractor required a rapid remediation technique in order to minimise disruption and maintain project viability.

Objective

The strategy for the Anne Street site was designed to address the source contamination onsite and indirectly the pathway contamination issues, with the intention of protecting Human Health and the identified groundwater receptors.

Methodology

Following an option appraisal of available remediation techniques, stabilisation with E-Clay was found to meet all the site constraints.
The remediation strategy involved the treatment of over 800m³ of contaminated soils.

Validation

A number of representative samples were leach tested and assessed against the agreed remediation criteria.
A Validation Report was prepared on completion.
