ABSTRACT
Geosynthetic reinforced capping of highwater content waste materials is becoming an
efficient and economic way of dealing with the confinement of the contaminants. To define the
filtration performance of sludge-geotextile systems and investigate their durability, ten sludge
lagoon test cells were constructed using of a lightweight fill, i.e. a wood chip/soil mixture over
different geotextiles. Instrumentation of the cells included piezometers, settlement plates and
surveying blocks. Various laboratory tests were performed on the field-exhumed geotextile
samples to understand their filtration performance.
The laboratory and field investigations showed that woven geotextiles could be effectively
used in filtering contaminated wastewater treatment sludges. Considering the constructability,
woven geotextiles should also be preferred due to their higher strength. Laboratory observations
performed on the exhumed samples can provide valuable information about the performance of
the geotextile.
INTRODUCTION
Considerable evidence has been provided by the recent studies (Grefe 1989, Zeman 1994)
