U - indicates that the anayte was analyzed for but not detected. Detection limit is numeric
value shown.
Q - indicates elevated reporting limit due to high anayte level.
All units are in mg/L unless noted otherwise.
NA indicates not available.
Bolded values=MCL exceeded, italicized values=reporting limit greater than MCL.
B - Estimated result. Result is less than the reporting limit.
a) MCL source: Table 1 Human Health Standards, Regulation 41.
b) MCL source: Table 2 Secondary Drinking Water Standards, Regulation 41.
c) MCL source: Table 3 Agricultural Standards for Groundwater, Regulation 41.
d) MCL for nitrate is 10.0 mg/L as N
e) MCL for nitrite is 1.0 mg/L as N
J - Method blank contamination. The associated method blank contains the target
anatyle at a reportable level.
