MONITORING NETWORKS AND METHODS The riverbed piezometers formed a series of 18 lateral profiles, comprising 2-5 piezometers, so that variations in the water quality and head across the channel could be studied. Five multilevel piezometers were installed to examine changes vertically through the riverbed across the groundwater-surface water interface. Groundwater quality data were also obtained by sampling a series of shallow piezometers (5-20m) adjacent to the riverbanks and across the northern section of the Tame Valley. This was supplemented by data on the deeper groundwater from the sampling of industrial abstraction wells (Shepherd, 2002). As a comparison with the urban water quality study, a background survey was undertaken in the natural undeveloped area (6 km 2 ) of Sutton Park to the north of Birmingham. Water samples were collected from springs, surface waters, 12 specifically installed riverbed piezometers and 4 shallow piezometers (Figure 4.3). Inorganic sample analyses were for a full suite of cations and anions, plus the measurement of field parameters, including dissolved oxygen, pH, Eh, conductivity and alkalinity. Organic analyses were for a full suite of volatile organic compounds including the chlorinated solvents and, for a few samples, vinyl chloride. During the course of the research a total of 324 water samples were collected and analysed (Table 4.1). Temporal variability in water quality was assessed by repeated sampling over the three-year period. Sample Type Number of samples analysed Surface Water 128 Riverbed Piezometers 139 Shallow Groundwater 43 Abstraction Wells 14 Table 4.1 The number and type of samples collected during the research. 61
