Fig. 8. Cross-sections showing variations in NO3–N concentrations in water from piezometers and deep lysimeters along three transects (W2, W1, W1rip) as measured in June 2001. Lysimeters are indicated by filled circles located above the water table, whereas piezometers are located below the water table. Installations not sampled for nitrate are indicated by a crossed symbol. Piezometer-nest identifiers are shown along the land surface. Refer to Fig. 1 and Table 2 for piezometer-nest and cross-section locations and identifiers.
