The former Pianoforte factory site is located to the south of the village of Roade in Northamptonshire. The site was closed in 2010. The site at closure covered over 11 hectares, consisting of a range of offices, warehouses and workshops.
The site is being developed for residential purposes.
Within part of the site was the former Anodising and Plating Shop. A number of investigative trial pits were excavated in the vicinity of the former Anodising and Plating Shop Area which showed that the underlying soils were impacted with heavy metal and cyanide contamination, derived from former plating activities. The prime
contaminant of concern was identified to be hexavalent chromium (Cr VI). Hexavalent chromium typically exists in an anionic form and is consequently very soluble and mobile within groundwater.
The remediation works comprised of three distinct stages:
Stage 1 – Treatment of the residual surface contamination on the plating shop floor and walls
Stage 2 – Installation of a permeable reactive barrier system to address contaminated groundwater potentially migrating from the former Plating Shop Area and
Stage 3 – Treatment of the source contamination in the Former Plating Shop Area (predominantly contaminated soils).
