E&RSC 25 June 2008
It was reported that
research had already commenced to find out
how similar investigations in other countries
were undertaken. Meetings with companies
who had previously expressed an interest in
remediating the site were due to take place
and a number of companies had stated that
they had cost effective technology to deal
with acid tar

Background
During 2008 Officers met with 3 local
companies none of which were able to propose
realistic solutions
In December 2008 Officers met with Guy
Pomphrey of DEC who gave a presentation of
his companies work on a site in Ertvelde,
Brussels. This remediation project was
featured in a CL:AIRE bulletin on acid tar
lagoons dated January 2008
