Dear all,
Just a reminder that the joint CIWEM/NWBRF evening talk on the 29th
September, at the Upper Lecture Theatre, Peter Jost Centre, Liverpool John
Moores University still has places available and is open to all.
Guest speakers - Hugh Masters-Williams and Martin Westwood (Jacobs)
.
The former Avenue Coking Works at Wingerworth near Chesterfield is one of
the most contaminated sites in Europe, and is thought to be the UK's biggest
and most complex remediation project. The plant opened in 1956, and at the
time was regarded as state of the art. As well as producing millions of tonnes
of smokeless solid fuel through the carbonisation of coal, the plant
processed by-products such as benzole, tar and sulphuric acid. It also
produced town gas, which was supplied for domestic use in Chesterfield,
and generated electricity for its own use, with the surplus fed into the
national grid. Following its closure in 1992, the works lay disused until East
Midlands Development Agency (emda) commenced the task of dismantling
the plant structures and cleaning the site in 1999.
The facility included a waste tip and settlement lagoons for the disposal of
hazardous solid and liquid wastes. Disposal in the lagoons was based on the
'attenuate and disperse' principle, which was an accepted technique at the
time. Contamination from the site, particularly the waste tip and lagoons, is
known to have polluted the River Rother that runs through the north of the
site. The former plant also contaminated the underlying soils through leaks
and spills from the numerous tanks, pipelines and sumps. Huge amounts of
hydrocarbons, asbestos, cyanide and arsenic still contaminate the 98 ha site,
the size of around 200 football pitches. (CEEQUAL)
The presentation will discuss the impacts on controlled waters and the
remediation techniques used.
