Remediation of contaminated groundwater at a site developed by Henley Homes in Bow.
The site is a 0.75 acre development for residential housing. The site was formerly used as a glass bottle factory, timber storage yard, an engineering firm, a furniture manufacturer and a printing and ink works. Historical use has resulted in soil and groundwater contamination across the site.
The remediation strategy was designed to address pathway contamination issues, with the intention of protecting groundwater receptors. The remedial operation involves the installation groundwater barrier, comprising both passive (low permeability) and active sections (E-Clay permeable reactive barrier).
The objective being to treat contaminated groundwater as it migrates off-site towards the adjacent River Lea.
