<br />1 Median values at stations with the same letter or number are not significantly different at the alpha = 0.05 level. Tukey's test was run on two station
<br />groups; group one: 07103747, 07104000, and 07104905; group 2: 07104905, 07103700, 07105500, 07105530, and 07105905.
<br />2 The median value is 0.1, the detection limit.
