Figure 6

Groundwater trace element concentration over a 20-day period. Note that trace concentrations are mostly inversely proportional to local rainfall, becoming more dilute with increased precipitation. Error bars are ± σ (standard deviation) of the ‘N’ replicate measurements used for the daily average concentration (see Fig. 5). Note that on certain days, concentrations of Ca and Mn elements dropped below the LOQ (filled Yellow) or the LOD (filled Red). Li was not detected.
