A combination of increases in population and increased frequency of low rainfall periods in Southern
England have led to concerns that predicted levels of customer demand will exceed current water
supplies. Water companies are undertaking investigations to identify water resource schemes that
address this supply-demand deficit.

Water quality baseline appraisal and model scenario testing is a requirement for the environmental
impact assessment of strategic and emergency water resource planning. In some data-rich catchments,
existing water quality datasets have sufficient temporal, spatial and determinand detail. However, in
many catchments, additional investigative monitoring is required. This can include the collection of
sediment deposition, automatic and storm event data.

This paper provides an overview of water quality work completed for these water resource schemes and
examines implications of the Water Framework Directive 2000/60/EC for future water quality monitoring.
Case studies will be used to illustrate the range of monitoring and modelling being undertaken in order to
inform on future water resource management schemes.
