construction and monitoring. Firstly, an assessment is made of QA procedures during liner construction
through the detailed evaluation of two case studies. Construction QA procedures on-site are compared to
available guidelines. The research illustrates the requirement for standardised, regulated QA procedures
on landfill sites in order to provide a recognised framework for construction control. The Moisture Condition
Value Test (MCV) is evaluated for use as a method of monitoring the placement of compacted clay landfill
liners. London Clay and Mercia Mudstone, collected from the QA case study sites, are tested in terms of
their suitability as engineered clay liners. Although, London Clay is the most acceptable it is this material
which exhibits the poorest results in the MCV testing. This is due to seepage from the apparatus at high
moisture contents. The research highlights the problems with the interpretation of the protocol for the
testing and the differences between the Scottish and English Road Research Laboratory guidelines (Green
& Hawkins, 1987). Thirdly, two airborne remote sensing techniques (ATM and CASI) are appraised as
methods of monitoring landfill gas, or possibly leachate migration, from two case study landfill sites in
South West England. Vegetation stress can be linked to landfill gas migration (Flower et al., 1981) and this
stress can be detected as a deviation from normal spectral reflectances in vegetation (Honer et a!., 1983a).
Anomalies are identified on-site through remote sensing but they cannot be directly attributed to the
landfills. This research emphasises the effects of contamination from other sources. It also requires the
use of a simultaneous ground survey to collate data from boreholes with measurements of soil and
vegetation types. Essentially, the QA case studies and the remote sensing show potential for future use
and suggestions are made in this thesis for further research. The MCV technique provides a method for
assessing the controlling parameters of compaction. With further development of aspects outlined in this
investigation there is the potential for specified use of these techniques In landfill engineering and
monitoring
