variability in the location of leachate pools also made it somewhat
difficult to keep the sampling points totally consistent.

                           Sampling Results

For comparison purposes, all ground water and leachate quality data
was compared to the ground water quality standards established by the
State of Wisconsin under NR 140 of the Wisconsin Administrative Code.
These ground water standards are based on a list of Enforcement
Standard (ES) contaminant levels that are equivalent to the U. S.
Environmental Protection Agency's Maximum Contaminant Levels (MCLs).

                             Ground Water

The five rounds of ground water samples collected from monitoring
wells at Site A and Site B were analyzed for a variety of parameters
including metals, inorganics and nutrients. In addition to these
parameters, each well at both sites was sampled once in June of 1993
for the presence of pesticide compounds. Each sample was analyzed
for the following commonly used pesticides: 2,4-D, diazinon,
malathion, chlorpyrifos, dacthal, captan, alachlor, atrazine,
cyanazine, methoxychlor, dicamba, chlorodane, and aldrin.

Site A

Nitrate+Nitrite as N was detected in every well and at each sampling
event, but downgradient well LR-4 frequently had the highest reported
levels of this compound. The highest reported nitrate level at this
site was 18.3 milligrams per liter (mg/L)-which was recorded at well
LR-4. At LR-l, the upgradient well, nitrate levels varied between
2.93 mg/L and 5.9 mg/L. The WDNR's Enforcement Standard (ES) level
of 10 mg/L was exceeded 3 times in well LR-4 and once at piezometer
LR-4P (Figure 2).

Ammonia levels were generally low in all wells with concentrations
ranging from below the detection limit (0.005 mg/L) to 0.11 mg/L in
well LR-3.

Sulfate was detected at consistently elevated levels in downgradient
well LR-4, ranging from a low of 120mg/L to a high of 340 mg/L. The
ES for sulfate in ground water (250 mg/L) was exceeded at LR-4 on two
separate sampling rounds.   In contrast, the upgradient well, LR-l,
had reported sulfate levels of between 28 and 46 mg/L. Well LR-2 had
levels similar to well LR-l and wells LR-3 and piezometer LR-4P had
slightly elevated sulfate levels.
Chloride levels were significantly elevated in all sidegradient and
downgradient wells in comparison with upgradient well LR-l.    Chloride
values in LR-l ranged from between 6.9 and 13 mg/L, but ranged from
between 22 and 170 mg/L in the side and downgradient wells.
Monitoring well LR-3 appeared to be the most impacted well with
respect to chloride.
