All monitoring wells were analyzed twice for copper and chromium and
at least once for lead and cadmium. Only trace amounts of these
metals were detected and there did not appear to be any significant
difference between upgradient and downgradient wells. Except for one
low detect in well LR-2, iron was not detected in any well. Zinc was
sampled at each well, but the results were erratic and no discernable
trends were noted.

The pH of the ground water in the wells was consistently above 7 and
did not vary significantly between wells.

A few other parameters, including Total Dissolved Solids (TDS) and
hardness, were slightly more elevated in well LR-4 when compared to
concentrations in other on site wells.

The pesticide analyses resulted in two low level detects. Atrazine
was detected at 0.13 micrograms per liter (ug/L) in upgradient well
LR-l and at 0.52 ug/L in piezometer LR-4P. No other pesticide
compounds were detected.

Site B

As at Site A, nitrate+nitrite as N was detected in all wells at each
sampling event. A downgradient monitoring well, WC-2, consistently
had the highest nitrate levels during every sampling round with
levels ranging from 5.63 mg/L to a high of 20 mg/L with a mean
concentration of 8.2 mg/L. In contrast, the upgradient monitoring
well, WC-3, had levels ranging from 0.865 to 3.7 mg/L with a mean
concentration of 2 mg/L. The lowest concentrations of nitrate were
found in piezometer WC-2P with concentrations that hovered around the
level of detection (0.007 mg/L). The ES for nitrates (10 mg/L) was
exceeded only once during the study at well WC-2 (Figure 2).

*Again, ammonia concentrations were generally low through out the
site. However, the ammonia levels in downgradient well WC-2 were
significantly higher than the concentrations in other wells with one
reading as high as 3.5 mg/L. Ammonia levels in the upgradient well
WC-3 never exceeded 0.032 mg/L.

The sulfate levels were generally lowest in piezometer WC-2P, but the
sulfate levels in the monitoring wells did not differ significantly
between wells. Sulfate levels ranged between 16 and 41 mg/L, with
the highest sulfate reading actually occurring at the upgradient
well, WC-3.
As at Site A, the chloride levels were significantly higher in the
immediately downgradient well, WC-2, when compared to concentrations
in the upgradient well.  Chloride levels in WC-2 ranged from 15 to 38
mag/L, in contrast to the levels in upgradient well WG-3 which had
chloride concentrations ranging from below the detection limit of 1
mg/L to 8.3 mg/L. All other wells had low level chloride detects
that never exceeded 14 mg/L.
